Doug,
I have cheated with hinges for two reasons, customer wanted them
yesterday, or didn't want to spring for a fully hand-crafted pair.
Most hardware stores sell hinges designed to be welded in place, they are
made with no screw holes. If you can find the size you are after, they
cut the fabrication time well over half. Texture the hinge leaves to
match your embellishment, re-shape or cut down to match the angle, and
gas or electric weld the embellishment to the leaf, drill new screw
holes to your customer's specs. Forming the barrell is, at least for
me, the most time consuming, and therefore expensive, part of a hinge
project. Peen the head of the factory pin a little, and burn off all
the plating. Finish with linseed oil, or something that will cover both
metals equally. The hinge material is usually different than your mild
steel embellishment, and will take some finishes differently, resulting
in a definate demarkation line between the two metals. Also, remember to
blend the weld line completely. To those who make hinges routinely, this
will sound like a lot more work than just making the barrell yourself
anyway, but I haven't acquired the skill yet, and it seems easier for
me. At any rate, it's an alternative, particularly if you have a big
order for hinges that require a lot of careful cutting and filing of the
barrells. We did two jobs of 30 pairs for a contractor. Totally hand
forged ones sent the guy into a fit, so we stopped and refigured. He
couldn't tell the difference between our finished (fabricated) and our
finished hand-forged. It took half the time, and we charged him 3/4,
everybody was happy.

I am not sure what you mean by this, are you talking about the hinge pin
that goes thru the rolled "barrel". Also what size stock are you making
these out of?
Here is what I can tell you. lets say you are makinmg a pair of hinges out
of 1/4 inch by 2 inch. First forge your decorative end to it's finished
state, next is really the hinge part, bevel the flat side if your hinge end
the same distance as the material thickness, in this case 1/4 inch, you do
this so after it is reolled you are not trying to cram a perpindicular end
into a circular rolled edge. Start rolling or curving your barrel over the
off side of your anvil so the bevel side of your stock will end up on the
outside of the barrel. Do this at a nice yellow hrat with many light
blows. When your barrel is about 2/4 of the way formed and starting with a
new yellow heat drive a drift the size of your finished hinge pin into your
partially formed barrel. finish forging with the drift in place. If you
have a swage block you can clean your barrel, (with the drift in), in the
appropriate swage in your block. the hinge would be upside down at this
time and you would be striking the back side of the barrel wherer it meets
the strap. If you don't have a swage block you maay have a top swage of
appropriate size and you can do the same process only your hinge would be
lying on your anvil with the finished side showing and you would be placing
your swage on the front of the barrel. Do not quench your hinge, after
normalizing drive your drift thru again cold and then try your finished
pin. If it is still to tight you can drill your barrel out the same size
as you pin stock. When drilling place your hinge so the turning of the
drill does not pull the barrel tighter and bind on your drill bit, when
you place your hinge for drilling look at it then tuen it over and look
again, you'll see what I mean.
> How in the world do you make the tail and strap, hinge parallel?
I am also not sure of your terminology here. Do you mean both ends of you
hinge ending up on the same plain? I guess it is mostly a matter of
keeping things true throughout the entire process. It sounds like you
might not be using enough heat anf forcing distortions along the length.
>am I expecting too much out of hand forged? I am desiring the same close
>fit that store bought ones have. This should be obtainable I would think.
>Or maybe, I am just trying to make a silk purse out of a sows ear. This
>being the analogy to my talents, not the capability.
No, you are not expecting to much out of hand forged, Do you remember the
first time you tried to parallel park? I bet it was a lot easier after 25
times and after 500 it was a natural process. Hinges are easier than
parallel parking, but the first few are still a challenge.
>I need help, advice or better yet, come on over and do these blasted
>things for me. er, just
>kidding...
You can take my advise for what it's worth, hopefully someone else will
also jump in here with more opinions, I am sure there are other ways and
tricks. But if you are still frustrated come on over and I'll show you
what I know, every Wednesday night is open forge.

MISCELLANEOUS TOOLS AND SOURCES:
As a follow up on my earlier post regarding plastic magnifing lens that can
be added to any glasses. They arrived and work as billed. Went out an
bought a new pair of safety glasses, washed the glasses and the new plastic
lens in warm soapy water. Postioned the lens on the safety glasses and blot
dry. Voila! There is a bit of distortion, but it isn't objectionable and
probably due to the curve in the glasses. The lens can be repositioned and
removed easily.
They have a web site www.neoptix.com where you can get more information and
order the product. This would be handy for use with welding goggles,
sunglasses, scuba masks as well as safety glasses.
Thought you old timers might find it useful.

I don't believe that there is enough metal to make a good hawk.
I buy virtually every (low priced) hammer that I find at garage sales. I
grind the pein end to make handled gravers. You can make them sharp similar
to walking chisels or dull similar to top fullers. I heat the metal and
then, using the pein-graver, mark borders, edges, or single or multiple
scored lines on the metal. Usually this is done on metal bars before
twisting. For example, by putting a single line down the middle of the bar
on all four sides, and then twisting, the bar looks like four smaller bars
were put together and then twisted.
By shaping the head, you can make one side much longer than the other. The
long side would guide down the edge of the metal and the shorter edge
actually makes the groove an even and consistant distance from the edge.
I have a variety of edges for varying effects.

***************
The anvil tool I mentioned is a helper for "drop the tongs" welds,
where a small piece is being welded to a longer one, like if you had made
the jaws to a pair of tongs, and were welding them to the reins instead
of drawing. Made of rebar, it is forged to fit your pritchell hole for
an inch, then bent to a right angle. Insert it into your pritchell,
measure to the far edge of your anvil, bend down 45 degrees, then another 45
the other way, so the top of the bar is now flush with your anvil face.
About three inches more and bend so the tail of the bar comes almost
parallel with your anvil side, and raises a little as it extends toward
your horn. Be sure to have the roughest part of the rebar up, keep the
inevetable seam on the sides. The support allows you to clamp the
smaller part in tongs with a ring. In use, the smaller element in the
weld is placed on the support, scarf up, and the rein part is pressed on
it, scarf down. You'll save the second or two most
important in welding, and you don't have to take a chance on
mis-positioning the two parts at a time when speed is of greatest
importance.

I made one out of that little thingamajig thet sits in the pilot flame and
has two wires connecting it to the valve. I hooked it up to an analog
voltmeter (0-3V) and made a new scale using a friend's real pyrometer.
Works real nice for brass and Al

Also, try www.dejanews.com and search for pyrometer. You won't beleve how

`Another idea for the steel balls, is to get in touch with a local
scale company.( one that services large truck and RR track scales). In the
process of converting some of the older mechanical scales to electronic
loadcells they usually throw-away the "balls and ballplates" and the knife
bearings. The balls(really just big ball bearings) and the knife bearings
are 52100 steel. The knife bearings are rectangular in shape with one long
side that comes to an edge.
The bearings can range from a few inches long (round for balls) to
several feet long and 4-5" thick (from a 1million lb RR trackscale). I
understand that the knifemakers love 52100. I used a piece for a cold
hardie, just welded on a stub and used it as is. These balls along with
their matching plates just might work for what you want.

A few days ago we discussed bending jigs. One small homemade one that I've
seen photos of was in the book called "Shop Savvy". That book, when I
searched at amazon.com showed to be out of print, though it's in my city
library. So I did a few drawings of this simple jig, put it on a web site
with description at, http://www.flash.net/~dwwilson/bjg/bjg.html
This is not a mini Hossfield. It's for small, hand bending of lighter
metal. Cost may be $5 depending on salvage finds. You can bend scrolls, "S"
hooks, etc., with it.

Ron,
MSC is one of the largest industrial supply houses in the country. They expect
you to have a business name before they send you a catalog, however you can
give them almost any name. When you get your catalog, you have an account set
up. No paperwork at all. The catalog is HUGE. This year's was about 3200 pages
hardbound. They sell a wide range of products. In most cases they offer a range
of quality/price. For example, drill bits range from low price imports to high
price, top of the line American-made bits - High speed steel, cobalt, TiN
coated and others.
Give them a call. Their shipping map says that Idaho should have two day
shipping. They try for fast turnaround times 24 hours usually.

plans for a shear. Capacity: " 1/4 x 4", 5/8 square or round, and 3/8 x
1-1/2". It looks fairly straight forward to build with a drill press and a
welder. Francis states he has been using his for 50 years.
Hope this helps

el doesn't seem to be in the
new catalogs) but it works like a dream. A friend asked for advice on
buying a hammer drill. I said, "Don't bother, you want one rated as a
rotary hammer for use in granite. Here try mine." so he went out to his
pickup and came back with a piece of granite he had been trying to drill,
put it into the post vice, set the drill pulled the trigger and then said,
"Jeez, the bit must be slipping back into the chuck." And then stepped
back speechless, he had drilled a 2 1/2" hole and didn't even realise he
had been drilling.
Before I bought the Rotary hammer, I went to drill 3/8 by 3" holes in 120
granite blocks for use as bases for an edition of awards. I drilled for 15
minutes on one with my old Milwaukee and still wasn't done. I figured if I
was going to get done before doomsday I had better find a better way.
I went to Fastenrite in St.Paul and asked my friend Tom for advice.
He asked me how many holes I had to drill, and then offered to loan me the
drill to use. 20 seconds per hole.
I bought it.

FIREBRICKS AND REFRACTORIES FOR FORGES: (See Also Volume #1)
I just bought 10 sq feet of a refractory felt called "Cerachrome" aerospace
insulation manufactured by Johns-Mansfield for $3.00 per sq.foot. Its rated
to 2600°F continuous duty, and higher for transient service. The spec sheet
says its unaffected by chemicals except hydrofloric and phosphoric acid and
strong alkalies. I dont remember the distributor (he was at the Blade
Symposium) but the address of the mfr is:
Johns-Mansfield Aerospace Dept.
Ken-Caryl Ranch
Denver, CO 80217
303-979-1000
You might can call them and get the name of a local distributor.

Hi all:
I played hooky from work today, due to an equipment failure and found a
company that carries one hell of a selection of refractories and
insulation.
It's the, "E.J. Bartells Co." They have offices in: Anchorage, Billings,
Mt, Denver, Co, Eugene, Or, Kennewick, Wa, Medford, Or, Portland, Or,
Renton, Wa, Salt Lake City, Ut and Spokane, Wa.
I picked up some 1" 8lb Kaowool for $0.60/sq,ft and a ramable refractory
with a working temp of 3,100f that's chemically resistant, especially to
caustics for $20.25/50lbs (1/3 cu ft). Hot borax? HAH! <grin>
The ramable is supposed to fire to a rigid but non-chipping/cracking
finish, it's supposed to be almost as tough as concrete at heat and very
abrasion resistant.
This stuff isn't even close to their high end refractories either, they
were out of the 3,300f castable I would rather have used but they had a
good supply of 4,300f firebrick, all the Kaowool products and lot's
more.
Just thought you'd like to know. <grin>

There is a product the I use for lining the forge called Super-G.
It is a refractory clay available in 100 # box from A.P.Green for
around $ 35.00. It has been replaced by a new but similar product
but I do not have the number/name of the new one.
To use the clay, break off a chunk, place it on your forge and with
a hammer pound it down until it is layered about 3/4" to 1-1/2"
thick. I recommend not lining the firepot but so the rest of the
forge.
After the forge is covered build a fire on the new clay using
charcol briquetts. Spread the fire over all the new clay and let
the charcol burn until exhausted. It is now ready to use.
One word of caution. Keep the forge out of the rain. Rain or
constant soaking will cause the refractory to disolve and break
down. Mine has been used for about 5 years now.
Hope it helps.

To all of you out there who have tried to use theforge
archives, I have compiled a few notes that may help you
get there from wherever you are. The instructions from the
forge itself are not exactly clear and then are written
for those who are UNIX versed, so I thought maybe a little
"Archives for Beginners" would help us all out a bit.
Theforge archives can be accessed by any subscriber to the
forge. Since theforge is a public archive, you don't need
to use a password for simple searches. This simplifies the
command line that you need to send.
There are really only five commands you can send to the
archive as a user:
index --> gets a list of all the files in theforge archive.
The list is not very creative, but is easy to understand:
There is one file for each month's worth of e-mails
and the names of the files are in this form:
log9612 --> e-mails from December, 1996
log9703 --> e-mails from March, 1997
log9511 --> e-mails from November, 1995
(see the pattern?)
These files are often quite large (between 1 and 2 megabytes)
and contain all the e-mails for that month that went
through the forge.
get -->actually gets a selected file from the archive and
delivers it to you in pieces of about 70kb via e-mail.
the 1.8 megabyte file comes in about 25 separate e-mails!
search --> searches the selected archive file or all files for
lines in the file that contain the selected search
pattern. It then echoes back to you, via e-mail, a list
of the lines it found and the file that it found them in.
Unfortunately, it only sends back the single line, which
often does not give much insight into the content of the
entry itself.
fax --> like 'get', it gets a particular file and sends it
to you on a fax rather than on e-mail. (I have never personally
tried this!)
view --> like 'get' but in interactive mode, just catenates the
file on the screen. ( I haven't tried this myself either!)
The commands are USED in the following manner:
You send an e-mail to 'listproc@wugate.wustl.edu' NOTICE that this
is NOT the same place that you send mail to the forge!!! That is
'theforge@wugate.wustl.edu'. If you send these archive commands to
theforge, you will get a pleasant nastygram informing you of your
mistake.
Also, the text of the command is put in the BODY of the e-mail,
NOT in the subject entry. You can put anything you want into
the subject slot, maybe just a reminder of what you are trying
to accomplish.
INDEX
to get an index listing, which is not very glamorous
afterall, simply enter this line only
index theforge
in the BODY of your e-mail.
You will soon get back a list from the forge of all the
files that you can download or search in the form
described above (like I said it is not very glamorous!)
SEARCH
If you want to search for a particular topic, you can
enter the following command in the body of the e-mail:
search theforge "pattern"
Substitute the string you want to search for for pattern.
Now here is the tricky part, if you do not know UNIX very
well or not at all:
there are several "operators" that can help
define the pattern you are searching for:
'&' - "logical and" - this allows you to search
for more than 1 pattern at the same time:
search theforge "books & clay"
searches for any LINE that contains both the word
'books' AND the word 'clay', but not necessarily
beside each other in the line.
'|' - logical or - this allows you to search
for lines that contain one or the other or both
of the entries:
search theforge "books | clay"
searches for any line that contains either books
OR clay or BOTH.
'~' - negation - allows you to exclude any line
containing that pattern: Unfortunately, I have never
been able to get the negation operator to work
properly. Perhaps if there is someone out there
that has, I can add it in here with an example.
Every time I have tried this operator, I get an
illegal message message.
('SURE', you say, 'Clear as mud' . . . Well, just
experiment a bit, what the heck!)
Anyway, you will get an e-mail back from the forge with a list
of all the 'found' lines and the file in which they are found.
Unfortunately, it only works for individual lines, which may
not give you much information. Ultimately, you will have to
download the file or 'view' it to find the answers. It DOES
help to locate significant threads that may have surfaced
in the past months.
GET
To get the file containing all the entries from the month
of May, 1997, simply enter the following line
alone in the body of your e-mail to listproc:
get theforge log9705
You will get back a series of e-mails containing the broken
up file. You may want to piece it back together.
Unfortunately, the files do not get delivered in any
particular order, so if you want to recombine them in
order, you need to search each one for the proper order
before recombining.
The nice thing about the way the files are stored on the forge
is that individuals files represent a time-block group (1 month)
rather than a topic. Once you have downloaded a particular
month, it will not be changed in the future. Eventually, you
can get the entire archive on your own disk as a reference!
This 'archives for dummies' is not an exhaustive treatment of
the archives access by users, but a tutorial in the basics and
how to get started. More detailed info can be found by sending
help
OR help archive
in the body of an e-mail to listproc (remember this is not the
same place you send the forge listings).
You will get back an e-mail with lots of good stuff about the
archive, but written for UNIX savvy users and somewhat
lacking in clarity for the uninitiated!
If I have misrepresented anything, please forgive me, given
the number of repeat questions and the references to the
archives, it seemed a prudent thing to offer a concise
tutorial to the process. If you have tried something else
that works, I will gladly add it to this file and republish!

Thanks to everybody for the info. I've been searching the net for hours,
which I rarely do, and I've learned a lot. For anyone interested, read on,
all others, move on (you've been warned)...
Now, I'm no expert, but here's what I've gathered:
Stainless steel, when ground, heated, etc, can leave iron molecules exposed
on the surface, which can begin the process of corrosion. This corrosion can
accelerate, causing serious problems in the long run.
A way to treat this problem is through stainless steel "passivation." This is
typically done in heated baths using a mixture of approximately 30% Nitric
acid and water. The problem I encountered was a lack of nitric baths in this
area large enough to dip the pieces I am producing. Nitric acid takes a while
to achieve the desired effect, so spraying the solution on was not a viable
option, as it would evaporate before fully passivating the surface.
I've just found a product (on the 'net) that the producers claim is being
used by some people as a spray-on solution. It is called CitriSurf
(1-847-854-2800), the man on the phone was very helpful. He told me this
product is a citric-based acid that works the same as nitric acid, only much
faster, thus making it possible to spray this solution on the piece. Another
benefit is that this product is much more environmentally friendly, and much
less toxic. Usual precautions of gloves, respirator, goggles, etc, are still
required.
This product was developed for use in baths as an alternative to the nitric
solution, but is much more viable as a spray-on treatment than the nitric due
to it's faster working time (about 10 minutes). It's available in 5 gal. and
55 gal. quantities, I'm getting the 5 gal. quantity, it's about $110, but
it's in concentrate form, and will make about 70 gallons. (that ought to last
me awhile!)
Once I use it, I'll report back about how it went. I guess the real test make
take a few years, so we'll see...
Usual note on this kind of letter: I have NO affiliation with this company in
any way, I won't even get a beer for telling people about it. :(

steve,
i've never used miracle grow for descaling but have used muriatic acid.
i have a rubber garbage can behind my shop about 3/4 full. it is mixed
about 1 part musiatic acid, (from the gallon containers available at any
hardware store) to about 5 parts water. pieces that will fit i just
suspend in the tub. if to big i paint the solution on, let sit about 20
minutes then rinse, and neutralixe with baking soda. i don't use this for
forged iron, just to get mill scale off plate steel prior to a rust or

Dan,
I've had good results from soaking forge welded pieces in phosphoric acid

If you want to see good atmospheric "junk", take a look at the Sandia Forge
(plans available from ABANA) that Robb Gunter helped design. I've seen a
lot of gas forges over the last couple of years and this past weekend I saw
my first Sandia Forge (built by Guild of Metalsmiths in MN). I was really
impressed with it's design and efficiency. Robb Gunter was using this
forge. It ran routinely at 5# pressure and he jumped the pressure to 12#
for welding. The pre-heat for the air heats the air to about 900 degrees.
That is not only a lot of recovered heat, it significantly improves the
efficiency of the forge.
The Sandia Forge is an atmospheric forge and calling it "junk" shows a lack
of knowledge of this forge. Some of the atmospherics may well be "junk",
but this one certainly isn't. After seeing it work, I'll take it and pass
on the forced air forges.
I don't know Hans Peot, but do know of him. He may be a gifted smith and
knowledgeable about a lot of things, but he is a bit off track on this.
At least that is what I think.

How about using lathe tool blanks. Any good tool supply shold have them,
our local welding supply even carries them. I buy mine ad a discount
industrial tool place for about $1.50 each, and they also have them in
1/8". If you need longer than about 2.5", you could weld the tool blank
to something else for the handle end. I have some gravers that I made
from used chain saw files.
Just my thoughts as my brain thaws out from the -20 degree trip into work
today.
Otto Bacon
**************
Ron, I would try an old file first. The carbon content in old files is
very high, and certainly much cheaper than buying some specialty alloy
off someone's shelf. There is a nasty rumor that new files are case
hardened mild steel with the teeth cut into the case only. So, I would
find a really old file at the flea market or someone's junk pile. Forge
close to final shape, and carefully grind and file to final shape, harden
and temper to staw for wood, softer for metal. Rule I remember is, the
harder the material to be cut, the softer the temper color.
Bob
***************
To All,
Drill rod is typically 1.2-1.3% C depending on the manufacturer. I think that
Cartech has a web page and they should list their tool steels and
compositions.
Files are red short to a fault. They will also fall apart if they get a
little too hot. I don't think there will be a problem in a gas forge but in a
coal forge just pay attention to what you are doing.
The plain high carbon tool steels do decarburize but not as badly as you
might think. Just leave enough stock for removal after forging.

Ron...Oil hardening tool & die steel (O-1 in this case) is (quoting from
the machinists handbook) "A low alloy tool steel with low tendency to
warpage. Used for cutting tools in applications where high heat is not
produced, such as taps and threading dies, press dies for blanking,
trimming, and forming dies in short to medium runs.
Any choice of steels is always a compromise proposition. You are
balancing hardness, toughness, ease of machining, resistance to warpage
during heat treat, cost, etc.
O-1 is a relatively inexpensive tool steel with properties that should
meet your criteria. There are better choices out there, but may not be
readily available inexpensively.
Enjoy the hunt.

*****************
Ron,
I have made gravers and chisels for carving metal from both O1 and
W1 tool steel they are both about .1% carbon. They work well for this
purpous. Ron you were wanting a higher carbon content but I think that you
will find that the higher carbon content will make the tools too brittle
and they will break in use. Even with the O1 and W1 steels I temper the
tool after hardening to a pale straw yellow this will reduce the tendency
to shatter in use. If you realy need harder tools then you need colbalt
alloy tool steel or other alloy steel . These are very hard to heat treat
without special equipment if you want to get the advertised hardness of
these special alloys. So I would start with O1 and W1 both of which are
sold as drill rod by most tool and machinery supply houses (Reid, Rutland,
McMaster-Carr).

Try a place called Metal Supermarkets. Their ad claims that they can
get whatever you want. I figured I would try them out.
I called in the morning asking for a 3' piece of rectangular S7,
1/2"x1". Not a huge order! That afternoon, they called me back with a
price of $31.32 plus shipping. I ended up buying a 12' piece of it for
$93. This works out to $4.42/pound, which is not a bad price for
rectangular S7.
Please note that these prices include a 15% discount for first time

I don't know the carbon content, but they certainly do make good engraving

While I've never tried it, what I saw worked great. And, the price is right.

I've just done what you're hesitant to do over the years..Actually I've
been turned onto old equipment that's just out in a field or scrap heaps that
are on old homesteads. Seems most of such stuff doesn't ever find its way
to the scrap yards unless the farm has been bought by a non-farmer/rancher
who just wants to clean up. Keep your eyes peeled on back roads. One
warning is that the conveyor steel rods are almost always still intact and
thus are linked together and are very heavy to move unless you take the
time to "unlink" them or have a cutting torch to cut them into managable
sections to move. Good luck

W1 tool steel can have up to that amount or more, but is usually in the
.80/.90 range. If you check W1 or "water hardening" DRILL ROD, you find that
the carbon is much higher, around the 1.05 to 1.25 range. Ask for mill

and retemper it. When I called the forklift manufacturer, they said that the
tang was made out of 1045.

I would suspect that if the stainless and was used in the food
processing industry it is probably a "mild" stainless and is not
hardenable. There are stainless steels that harden and are a favourite
of todays knife makers. Namely ATS34 and 440C. these are usually air
hardened. I really don't think that a stainless would make good punches
and chisles.
You would be better off trying old struts from the auto industry. These
are often an "S" ( shock resistant )type steel and harden into some
dandy punches and chisels.
Stainless also doesn't fare too well in a coal forge as it soaks up the
sulfer gases produced thereby ruining the steel.
I have forged some ATS34, not into punches but rather into a hook. Just
had to try. It is "Red Hard" ( doesn't move too well even into orange
) It also retains a lot of stiffness and is difficult to shape. Be
carefull not to get it too hot or it does "red short"...

<< This would be directed more to Steve Rollert. Myself a novice in knife
making, I read all sorts of articles by master knifesmiths who make thier
wares from exotic materials such as D2, A2, L6, AST34, etc, etc, & and so on.
My experience as a diemaker ( actually die maintenance ) has shown me that
most of these materials are expensive, difficult to heat-treat properly, and
once sharpened do have an extremely good edge. However, once chipped or worn,
is very hard to hone back to a sharp edge. They would be OK for a
presentation piece or show piece. But I would think that if you were going to
make a good utility/hunting knife, you would want a good tough material such
as 1065,1080,1095, 5160 and the like.
I also need to find some of these knife making classes in my area.
Presently, I don't have the time to take off of work to attend some of them.
I suppose I'll have to break down and buy a few good knife making books. And
I appreciate the hint on the hint on making the cutler hammers from a rail
spike hammer. Now my only problem will be to find one of those.

With the proper heat treat and temper the "exotic" steels as you put it will
hold up very well under normal use. If you chip an edge, you are abusing the
knife, period. You are right that it will be difficult to resharpen these
materials, but the amazing increase in cutting ability is well worth it. The
other tool steels you mention also make good knives, no question about that.
One of the main considerations when choosing the steel to make a knife out
of is what the knife will be used for, and what type of person will be using it.
If you don't already have it, "The Complete Bladesmith" by Jim Hrisoulas
should be required reading material for all budding knifemakers IMHO.

***************
Many leaf springs are 5160, some are 1060-1080 hi carbon steel. All of these
are considered low allow steels and can be annealed by heating to a uniform
dull red color and packing in vermiculite or wood ashes or powdered lime and
letting it slowly cool down overnight.
Heat treat by quenching from a red to red-orange color in oil (30 wt motor oil
will work). For these steels you can verify you are at the right temperature
by checking the hot steel with a magnet, when the magnet won't stick anymore
you are hot enough. Then temper in an oven at 350-450 degrees for 20-30
minutes three times with an air cool in between each temper session. The
higher the temper temperature the softer the tool will be.
Use a file to check the hardness, after the initial quench and before tempering
the file should skate accross the surface of the steel without biting in.
After tempering it should just barely bite in. How hard you leave it after
tempering depends on how it will be used.

Experts of the list...
And compared to me the rest of you are just that. Want to start out
today by thanking everyone for being such a great group of people,
I've learned more lately then I can ever hope to keep in my limited
little mind (especially whilst trying to pass College Physics).
Anyway, my question (seems I have only questions and never advice.
The guy who is getting some scrap steel from a spring place for me
brought me a phamplet that they handed out during one of their
mandatory classes. It lists the steel that they use. Some of the
steel types I have never seen before so I thought that I would ask you
guys and see what you had to say. Here is the list
SUP 6 - mainly contains silicon, which raises the elastic limit; and
manganese, which improves hardenability
SUP7
7 - contains more silicon than SUP6. Silicon raises the elastic
limit and helps the spring risist permanent set. Care must be taken
with its use because it makes the spring more susceptible to
decarbonization.
SUP 9A (5160M) - Manganese and chrome are added to increase
hardenability so that it can be used for items which are thicker than
the ones using SUP6 and SUP7.
SUP 10 - Chrome and vanadium steel improves hardenability and
toughness for springs which will undergo great stress
SUP 11A - boron has been introdued to provide better hardenability
than that of SUP9A. It can be used with thicker springs than those
made with SUP9A.
SUP 12V (SRS-60) - Chrome and vanadium have been added to SUP6,
prividing great resistance to permanent set throught refining of
crystal grains.
SUP7 OTW - Materials with components of SUP7 are preheated (tempering
and cooled (quenching). (This doesn't makes sense to me, the order
that is, and I am assuming that the terms are are not right, switched
or I don't know what I am talking about. The phamplet goes on to talk
about the structures involved in heat treating, gives temperature
versus time charts which show grain structure, etc. so I am baffled by
this.)
ND 250S - Hass a lesser amount of carbon than other spring steels.
Nickel, molybdenum and vanadium have been added to it, making it
harder than previous springs. It can be used under high stress
conditions.
The list of things that they are used for is as follows:
SUP6 - Leaf Springs
SUP7 - Coil Springs
SUP9A (5160M) - leaf, coil radius rods, torsion bars, solid
stabilizers
SUP10 - Leaf Springs
SUP11A - Leaf Springs
SUP12V (SRS-60) - Coil Springs, Torsion bars
SUP7 OTW-D - Cold formed coil springs
S45C - Induction hardened torsion bars
S48C - Sold stabilizers
ND25OS - Coil springs
They also list ASB25N which is a seam welded pipe containing boron to
improve hardenability for water quenching. This hollow stock is used
for stabilizers.
I know what 5160 is and I am assuming that 5160M is for the manganese,
am I right? If nothing else this kinds gives a really clear picture
of what kind of stock modern springs (including many foreign cards to
include Honda and Nissan as this company is making springs for lots of
cars) are made out of. Hope that this isn't repetative and if anyone
can clue me in on what this SUP stands for and what types of steels
these are I'd appreciate it.
Thanks,

I visited a metalworkers shop yesterday and was shown a fine looking
treadle hammer. It has excellent craftmanship, finish, and balance with a
leaf spring system. A fine tuning wheel adjust it. This hammer is 125 lb.
and cost $1000. So I called the guy, Cliff Yeary, that builds them and I
hope to have a picture soon. He is building another design that he says is
much improved! The new one is 130 lb. and cost $1200. He is trying to get
his hand drawn plans and operating manual on a computer. Cliff said that
hammer construction turnaround is about three days now. Possibly will sell
the plans, and he mentioned making some tooling such as dies, swage block,
etc., also. With his permission, I'm posting his name, address (no email

The Sheppard hammer uses a "rocker arm" type mechanism and the ram moves
vertically; the Spencer-style hammer uses a "swing arm" type mechanism
and the ram moves in an arc. In my experience, the Sheppard hammer has
less "snap" and more force of impact is transmitted back to your foot
via the direct linkage of the design. The only other disadvantage of
the Sheppard hammer is the more limited clearance between the ram and
the anvil; however, I haven't found that to be a problem in my work.
The Sheppard hammer is more compact, and the vertical path of the ram
negates the need for adjustment for different size stock or workpieces.
I've had a Sheppard (Tick Creek Forge) hammer for two years and been
very pleased with it. The only improvement I could suggest is use of a
solid anvil post rather than the tube-filled-with-concrete anvil post
which mine has.

Always the heretic, I'd like to weigh in on treadle hammer anvils....
I have built a few treadle hammers. I use two currently, one in the shop
and one demonstrating. Both have hollow columns. I have never found the
lack of weight to be the slightest issue. I have found that regardless of
weight, having used just about every type around in demos that I have flown
to (no treadle hammer fits the overhead luggage compartment), that they do
need to be bolted down. I have also found a distinct advantage to the (4")
square tube (1/4" wall) column left empty....you can drift through a slit
hole. I have cut an opening in the side and put an angled piece of plate
about 10" below the bottom plate. This allows a drift to pass through and
out of the tube column into a bucket of water. In 10 years of almost
daily use there has been no deformation of the tube wall. In as many years
of demonstrating on other types I have not noticed a disadvantage in the
lack of 'anvil' weight.
I also have the original ABANA plan springs on all of the ones I have
built. They are 8 smaller-wire type springs that are very easy to extend
on the downstroke and they give a quick return. An advantage of this
approach is the rapidity of stroke, for layout and fast multiple passes as
well as the fact that less effort is needed to extend those springs in
general to make a blow. All the spring does is return the head to the
upright position so a stiff, heavy spring can make the work more tiring
and the hammer less responsive as you work to overcome the heavier
spring(s). The light action of the hammers I use can be illustrated by the
fact that I can do layout chisel cuts, incising and repousse' just flexing
my ankle. A full stomp moves the head very fast, thus imparting a lot of
energy through the tooling into the stock for splitting and fullering. The
head weight is about 85lb.
The springs lifting head of the treadle hammer should allow it to float
just enough to raise it into the starting position, any more 'lift' is
simply more to overcome on the leg operated down stroke. The head should
be at a balance where the spring overcomes the head-weight and no more.
Head weight and velocity (overcoming the springs lift) of that head gives
the hammer its heavy swat.

The hammer does good heavy blows but remarkably can do som very fine light
work as well.
>If you think of any thing else about the hammer I would love to hear >it.
The springs at the back have a hose around them to cut down on the noise.
The back vertical tube is filled full of sand, the front one the anvil
rests on is sand about half way & then concrete. The anvil comes with it's
own ...I guess hardy hole..which has a tapped screw into the side so the
tool won't slip. It comes with an optional 1" thick round plate that slips
into the hole to do work on....whcih also has an ofset hardy hole for
helper tools.
The head slides inside a another square tube, about 5-6", which also has
the sides tapped for a screw fitting in which a silicon bushing sits (3
sides) which helps the head move smoothly without any problems. The unit
itself weighs about 550 lbs & has a fairly small foot print. they were
using them on top of 3/4" ply over the dirt so they are very stable when
using them.
Hope that helps....

I purchased one of Richard Sheppard's Tick Creek Forge treadle hammers
from the first batch he made. I've been very pleased with it. The
major advantage is the the vertical motion of the ram, which negates any
adjustment for work piece/tooling size. It is a very compact design
and, in my opinion, well made. The disadvantage of the vertical motion
ram is the fixed and limited clearance between ram and anvil, which is
about 11 inches on my model; tooling height needs to be kept to a
minimum to allow for maximum travel of the ram. Also, the rocker-arm
type linkage between treadle and ram seems to transmit more impact shock
back to the operator's foot/leg, but this has not proven to be of
consequence in my experience. In addition, I feel the Sheppard hammer
has less "snap" to the blows than the Spencer-type/swing arm hammer;
however, with an 80+ lb ram, the hammer delivers sufficient force for
most purposes.

Lately I've been using it for "step over" forgings. I've just finished
ironing a house with step overs being a part of the theme, they were used
on fireplace doors, mirror and picture frames, and some trim work. I made
a top and bottom form and used the Big Lick for the forging. It worked
great. I also am amazed how often I am going to it for a quick "flatter
run" across a piece of iron to level it up. I have a flatter that lives
just next to the Big Lick. This use may be more important to me than
others as my 260 lb Peter Wright has about a 3/32 nd saddle in it.
I also use it for top working iron, you know that kind of work that is
somewhat akin to leatherworking, I have about 3 coffee cans full of
different top tools for surface work.
This is just a small sampling of what it can do, and these are all examples
of procedures I would not or could not do under a power hammer. I am
looking forward to seeing a video of Clay Spencer demonstrating on the uses
of a treadle hammer. I am sure it will enlighten me further. I ordered
the tape from:
http://www.artisticiron.com
An outlet for Blacksmith products & video tapes. I have not received tyhem yet.

Dear Ron;
Sorry I have not gotten back to you sooner. I have been very busy,
but also have had some computer problems!!!!
As for the hammer, I am not currently planning any trips out west.
I may be in the midwest (Missouri), at the next conferance there.
Otherwise, I am not sure. If you want a hammer, we might be able to arrange
something with a carrier going your direction that would not be so
expensive. I'll keep checking and maybe so can you.
As to tools. I am currently making a 12 piece set, (6 sets of 2
each), which sells for 149.95 plus shipping. I accept Master Card and Visa.
Was great hearing from you and hope all is well with you and yours.

HYDRAULIC PRESSES: (See Volume #1 also)
I finally finished the hydraulic press that I started back in January. It
has 15" platens with a post guided die set for holding coining and other
types of dies. I built all of the innards first so as to make absolutely
sure that there would be plenty of daylight available. It has a 50 ton
cylinder with a 6" stroke and an electric pump system.
Taking advice from AM I used the 7018 rod and probably have over 60 linear
inches of weld on each corner of the press.
I love it. Now I just have to figure out what color to paint it and build a
steel table to hold this monster.
Thank you Lee, Frosty, Valerie and everyone else who helped me with this
project.

To all those interested:
The basic rule of thumb is: 1hp= 1gal-min@1500psi
This rule applies to electric motors.
other rules that follow from this one are:
1 electric motor hp= 1 1/2 hydraulic motor hp
1 gasoline engine hp= 2/3 hydraulic motor hp
1 hydraulic motor hp= 1 2/3 gasoline engine hp
1 hydraulic motor hp= 2/3 electric motor hp
1 electric motor hp= 2 1/2 gasoline engine hp
and I'll bet you thought a hp was a hp ...........hah! but from
this you should be able to figure your needs. The other thing to figure is
the cubic inches in a gallon
I think the 38lb/ft I beam is a good idea for a 24 ton ram.That
is alot of power. You could easily bend 2" schedule 40...........(cold!) so
think what you could do hot!.........next step is to think about lifting it.
Hydraulics are great! Ralph

Used machinery dealers in the north east, Rhode Island (a hot-bed of fly
presses) and Mass. for example, often have them. Look for triple-lead
screw type presses, they have more travel vertically per rotation of the
screw so they are faster in cycle for hot work. A yellow page search of
larger cities up there would probably produce leads.
One approach that served Tal Harris, Pres NC ABANA, was to look in the
Thomas Register at companies which were both in the press using industry
and were old. Many he called had old presses still around but unused since
hydraulics came along.

Greetings,
I use a fly press for various tasks in architectural scale forge work. The
fly-press is best analogized as a mechanical version of a hydraulic press.
The ones I have take 1" round shank tooling in the end of the ram. This
allows chisels and drifts to be made for slit-and-drift operations.
Slitting a 3/4" thick bar is a one heat operation with the larger one.
Drifting holes for 1" bars is also a one heat event.
The next job calls for English Half-penny snub end scrolls. The press is
being tooled to isolate the material for the snub-end and start the taper
of the scroll in one operation. The snub end will still be hand forged on
a snub end tool, but the blank with taper will save at least 2 weeks of
prep-forging.
Bends, both curved into swages and square into V-blocks can be done with ease.
Straightening forged bars, using a flat faced plate on the end of the ram,
is very quick work. I hand reforge every inch of every bar before a rail
is started, so there is a lot of straightening. 5/8" X 2" or 3/4" X 1
1/4" bars are no problem. And it goes fast.
Offset bends are a breeze, the tooling is simple. One thing I like about a
fly press is that you can feel the effect as it happens since you are
actuating the thrust by hand. There is less (almost no) chance of applying
too much pressure. The cycle time is also much faster than a hydraulic
press.
All manners of set tool work can be done on the fly press.

Ron, could you post a picture of this, please? I have a mental picture
of what's going on, but figure it's not quite right.
I second your notion of making your own bits. Some years ago I used to
teach jewelry making. (Patience please, there really is some
blacksmithing coming up here.)
Jewelers do a lot of pierced work. That is, drill a little hole, thread
the jeweler's saw blade through, saw an interior shape, remove the blade
and repeat until the piece is sawn to shape. A jeweler's saw is tiny.
Shapes are small. This means a small drill (say a #60 or so). 20 years
ago, a #60 drill cost about 80 cents, buying one at a time.
Students tend to break LOTS of these bits. For a while, I simply told
them to supply their own, figuring that they'd be more careful. Finally
I realized that most of them were simply learning fine motor control in
their hands and fingers, and were physically incapable of the control
necessary to work at that scale. I added a demonstration to my teaching
cirriculum -- making tiny drills. Here's about how it goes:
Required components:
Sewing needle
Alcohol lamp
3-in-one oil
Pliers
File
Jeweler's bench block (polished steel)
Jeweler's hammer (chasing hammer OK, I prefer rivetting hammer)
1. Light the acohol lamp. Have the bench block next to the lamp.
2. Holding the needle by the eye in the pliers, heat the tip to red
hot in the flame of the lamp.
3. Forge it flat on the bench block. (if you can't do this in one
heat, you're moving too slow between heating and hammering.)
4. Let the needle air cool.
5. File the flattened tip of needle to the diameter of the hole and
shape the tip to a spade bit shape. Angle of filing creates the
relief for the cutting edges.
6. Prepare a quenching container (I often used a soft drink bottle cap)
and put some 3-in-one oil in it.
7. Heat the point to red hot and quench in oil before it loses color.
8. Come right out of the oil and hold it in the alcohol lamp flame just
long enough to ignite the oil. Pull it back and let the oil burn
itself out. This draws the temper to just about the right point.
This little demo was really an eye opener to a lot of students. The
look on their faces when they could see two little curls of metal coming
off the point of their drill was amizing.

Hello All,
The neat thing about these triangular holes is that if you use calipers or
a telescope gage to measure them with, they will measure the correct
dimension all the way around. This is one reason why in addition to a good
finish, precise holes are usually reamed or bored on a lathe. Any two
fluted drill which is used to drill a hole without a pilot hole will do
this to a certain degree. The higher the tool pressure the greater the
effect. If you are looking for cheap reamers for round holes try a D-bit
reamer. You make them yourself from drill rod. There is a book called the
Machinist's Bedside Reader written by Guy Lautard which is full of good
stuff like D-bit reamers and other types of neat tooling ideas. How about
using milk as a tapping lube for copper? It's in there!

ANVILS AND ANVIL REPAIR: (See also Volume #1)
From: Matt Balent/HCS/CSC on 02/06/97 07:23 AM
I used 'super missile' rod from Arco after a 400 degree pre-heat.
Make sure you use some sort of heat sink on the surface or you
could lose temper.
Been using the anvil for over a year now with no problems.

**************
I recently repaired some fairly serious damage on mine by preheating to
400 degrees and welding with a hard facing rod ( 6700 from UTP.) I
wouldn't skip the pre-heat, I think you could get some cracks without it.
Mine seems to be working well.

Subject: Re: Repairing anvils
I have gone to the trouble of repairing several anvils by welding on new
plates. It does not take as much time as you might think, but several things
make life easier.
Although I've used truck springs for the plate with success, I also had one
fail miserably. Maybe it was work or weld stressed or maybe it was
overheated before quenched, but it cracked horribly and had to be rewelded.
Conversely, I've had several work out well.
The only time I would recommend this process is to restore extensive damage
on large anvils that are worth the time. The basic procedure is to gouge off
the remnants of the old plate and "V" the top of the anvil to provide a root
for the welding. Drill/cut the hardie and pritchel holes in the new plate
with drill/torch/die grinder to match existing holes. Make sure the plate is
stress relieved before welding. Tack it squarely in place and preheat to
about 300-400 F. Weld from the center out and fill the entire root until
there is a protruding bead that can be ground flush without leaving traces of
the weld (undercuts, puddles, etc.) I either use a MIG or an E6011 rod and
don't clean the welds - I just weld right over each pass (you can't do this
with rods that leave heavy slag). Although I can't prove it, I think now
would be a good time to bring the anvil to critical temp and let it normalize
in the atmosphere, but I have hardened several without taking this extra
step. However, the cracking incident has made me wary.
The forge I made to heat anvils is a piece of plate, 3'x3'x1/4", set on 3
legs (I'm lazy) with a slot cut in the plate about 1/2" wide and as long as
the anvil face. There is a long piece of square tubing welded to the bottom
of the plate as a tuyere. The fuel is coal and the air can be a manual or
electric blower. I make a collar encircling the anvil's waist with 1-1/4"
pipe arms sticking out to allow manipulation and so a piece of 1" pipe will
slip fit. Two men can handle a 300 lb anvil in this manner without too much
trouble. Personally, I use a tractor with gin pole to pick it up with the
3-point or you could also use a hoist. You must also provide some method of
supporting the anvil while it heats - I make two simple "A"frames, welded to
the plate which hold the pipe so the anvil is about 2-3" above the slot. The
fire is started first and when it is going over the full length of the slot,
the anvil is put in place. Pack lots of damp coal around and keep the blast
low to medium, making sure the fire does not burn hollow under the anvil.
The heel will heat up first because it is thinner, but you can usually heat
a 250 lb anvil to critical temp in about an hour. At this point, you can
either quench in a large water container (like a cattle trough) or you can
pour a continuous, heavy stream of water on the anvil face. I fill several
55-gallon open-top drums with water, say a fervent prayer and start pouring
FAST to drop the critical temp quickly. Be wary of the steam! After the
water is gone, I play a garden hose on it to finish the cooling. If it
hasn't cracked, it can now be finish ground. I don't temper and I can't say
whether it is necessary. My main "battle" anvil is a 250 lb Peter Wright
that I repaired this way and it has lasted under regular, heavy use for 10
years.
Caveats:
1. If you use scrap for the plate, do thorough testing before welding it on
- it's probably safer to buy W1 in the right size.
2. Stress relieve!
3. Don't overheat the face - not much heat is needed to get to critical
temp. Better to have a slightly softer face than a glass-hard surface which
chips.
4. Be careful!!! - this is a BIG, HOT, HEAVY piece of steel.
Work time for me to replate an average anvil is 12-16 hours - you might be
faster or slower depending on skill and initiative. I have also done
build-up work with rods - I use Certanium, but Stoody and Palco are good,
too. Don't use standard low-hydrogen rods for build-up.
A couple of years ago, I wrote a summary of this method with sketches in the
Anvil's Ring. If anybody wants further detail, you can E-mail me with
questions/comments.

Steve,
I sold Certanium rods for about 6 months (the source of my ever dwindling
supply) and the tech guys told me that low hydrogen rod does NOTHING for
carbon steel. Their reasoning was that any time you weld on carbon steel,
you get carbon embrittlement due to the dissolution of the carbon into the
weld pool. For example, say you were welding a piece of 1095 plate with
low-hy rod. You would probably get spots in the weld deposit that were .5%
and others that are over 1% creating an imbalanced structure. The party line
at Certanium was that the specialty rods are supposed to create a ductile and
homogenous weld zone. Their demo was to weld two pieces of a file
edge-to-edge without preheat, then clamp one end in a vise and beat the file
first one way and then the other. Usually, the top piece would bend 90
degrees to one side and then BACK 180 degrees. They swore that no common
rods would meet this test. All this said, I can't say with certainty that
your 9016 rods won't work. Try it and see - just make sure you pre and post
heat to minimize chilling.

OK Dave
Since you have a 250 amp MIG life will be pretty easy.
Grinding the surface with a coarse 9" right angle grinder will help true
it up, but to build up the edges and fill holes you will need to lay down
some hardface.
If you were stick welding then you would need to go through the usual
rigamarol of preheating to 400 deg F and allowing it to slow cool.
Since you have a MIG life will be much easier. Rankin makes several
hardfacing wire products that work wonderfully.
For general buildup I use Rankin BBG ( rockwell C47 ) , and for the final
surface I use Rankin DDG ( rockwell C56 ).
The wires come in .045" and .065", but the you will only be able to run
the .045" in a 250 amp MIG, since .065" wire requires about 350 amps.
The Rankin hardfacing wires are actually a dual-shield product. This means
that they are flux-core wires that are run with a gas sheild.
Dual-shield burns very hot so no preheat is necessary. To fill holes
first you need to gouge out the holes with the edge of a grinding wheel.
The idea is to grind out the cracks and any gunk that is wedged in the
holes. If the edges are cracked then grind them too.
Any surface that is to be hardfaced must be ground first to get rid of any
contaminants. If your anvil is cast or forged steel then you can also
hardface the horn.
If it is cast iron then you have to lay down a layer of nickle rod to act
as a buttering pass. Then lay down the hardface on top of that.
Having a hardfaced horn is really nice.
I rebuilt the face on an old trenton anvil last year and I went ahead and
hardfaced the horn while I was at it.
You will be running the MIG at almost full power, so be prepared for some
heavy welding.
Personally I love the Rankin wires and would never go back to stick rod.
The odd thing about the rankin wires is that you end up with a layer of
fllux that cools on top of the bead just like stick rod, but the flux self
ejects as it cools. So some light tapping and it falls off real clean.
Make sure to clean off the all flux before laying down a second pass to
prevent flux inclusions.
Lay down beads of about 3/4" width and make sure to weave as you go to
spread it out.
You will find that the anvil will get quite warm as you progress.
If as you grind off the added metal you find small pockets you missed,
just fill them in.
Be careful about hardfacing around the hardie hole since grinding it out
can be quite difficult. A handfile will cut the BBG wire, but the DDG is
way to hard.
It's like filing glass.
If you wanted a harder surface, they also make a hardfacing wire that has
Tungsten Carbide in it ( rockwell C62 ).
I usually paint my anvils with Hammerite and clean up any markings with a
hand chisel.
Best of luck

Yep. Just weld about an inch an stop and let it cool - or cool it
with a cup of water but be careful not to get your feet wet and
become a better ground than your cable is.

Yep. Works great. I fixed the wallowed out edges of my hardy hole
this way by using a piece of brass about 3/16" thick and 3/4" wide.
I used 7018 low hydrogen rods. They work harden a little but not
enough to become brittle. It will ding a little if you hit with the
edges of the hammer but holds up well enough as long as you don't do
any forging of cold iron on it.

Phil: Copper will work better and put a spacer between the plate and
the anvil, say 16ga., so that you have a bit to grind away. You won't
need any of that if you are just welding a few inches at a time. Just be
sure that you pein your weld diligently after each 1/2 rod and then go
to the other side of the anvil for the next 1/2 rod. This might be a bit
of overkill but the start of a long weld will be quite cool by the time
you burn a whole 5/32 rod. I would use Stoody 2110 since your only
building up corners and have no room for a harder cap. Just be sure to
pein it plenty before you grind it because this is essentially a buildup
rod but it will work harden to 40 - 45 Rc in two passes. Grind the edges
of your anvil first. This is a cast steel we're talking about.

I show Stoody 1105 as a buildup rod and 2110 as a hardfacing rod. I
think that the 2110 reaches something like 53 Rc (with the 40-45 Rc
being right for 1105).
Stoody 2110 sometimes has a hard time sticking to anvils. If you are
welding to a tool steel top plate, it will probably be ok. If you are
welding to the anvil body material, watch for cracking. What I've seen
happen is that a crack can form all along the edge of the bead. If
this happens, then you need a buildup rod, such as 1105 (or maybe
preheat, or more wirebrushing..).
Preheat isn't too hard to do with a weedburner. Note that the
temperature of 400F is chosen so that you do not lose any of the
hardness in the rest of the anvil. This means that you don't need to
re-harden and temper your anvil. The Stoody rod work hardens. Don't
exceed 450F if you want to not 'lose your temper'. A welding
instructor told me that you probably only need 200-300F preheat, but I
haven't tried this. Insulate the anvil when done so it cools slowly.--

This is sure a complex subject.
I've talked with two different guys on the Stoody hotline
(800)832-4123 about rebuilding anvils. I'm convinced (was convinced
before, actually) that there are no simple answers here. I'm going to
try to summarize what I've got so far.
The procedure that works depends a lot on exactly what the composition
of your anvil steel is (as has been said here previously). The only
thing I've tried is 1105 first, 2110 on top. This works on Peter
Wright anvils. It will not work on cast iron (i.e. Vulcan), may be
likely to work on wrought body anvils like PW. This is all I can speak
of from my own experience. Before you blow a bunch of money on rod,
get a sample and see how it welds on the anvil you intend to
rebuild. A couple of years ago, I paid $3.50/lb for 1105 and $5.20/lb
for 2110. They come in 10lb. packages, so it adds up fast.
2110 rod is good at bonding dissimilar steels together. It is about 20
Rc as deposited, and can work harden into the low 50's after
substantial deformation. Abrasion resistance is good, impact
resistance is excellent. The impact resistance is why it is a good top
layer. 2110 is high in Chromium (13%), and is essentially a kind of
stainless (I think). Uses include surfacing (buildup of) roll
crushers, shear blades, shovel teeth and hammers. No limit on layers.
1105 rod is an air hardening tool steel. It is 43 Rc as welded, no
hardening needed. Bonds well to carbon and low alloy steels, not
recommended for manganese steel. Moderate abrasion and impact
resistance. LIMIT 4 layers. Uses include shovel rollers and idlers,
sprockets.
1102 is similar to 1105 but harder--54-58 Rc as welded, H12 air
hardening tool steel. Relatively new rod. Abrasion resistance
excellent, impact strength good, compressive strength high. LIMIT 1/2"
(4 layers nominal). Uses include forging dies, crane wheels, hot and
cold shear blades. Good for hot wear up to 1100F.
All three rods are AC or +/-DC. I've only used DC reverse. Note that
Stoody says that none of the rods should show any cracking if put down
on an appropriate base with sufficient preheat, contrary to a previous
letter on theforge.
The first Stoody guy I talked to said that if the 2110 cracks when put
down first (which fits my experience), then the base material is
acting as if it were a cast iron (which it is not-Peter Wright). He
said that if the 1105 welds without cracking, just use 1105, don't
bother with the 2110. The second Stoody guy said the 2110 was
definitely the stuff for a top layer due to its impact resistance.
They also said that what works works. If you have experience with an
approach that works, stay with it. A lot depends on exactly what type of
steel you are welding to, and this will vary a whole bunch from one
anvil manufacturer to another.
I end up finding his recommendation of 1105 only compelling (if it
bonds well to the base material). 1105 is cheaper for one (3.50
vs. 5.20 per pound). As for needing a harder top layer, I haven't
gotten much if any deformation out of my top layer 2110, which means
that it hasn't done much hardening-- 20Rc according to Stoody. The
limitation here is that they only recommend a maximum of 4 layers of
1105.
The second Stoody guy suggested another combination that should work
is using BuildupLH first, topped off with 2110. (Note here that I am
getting different recommendations from two different guys, both at
Stoody). This will not work on cast iron.
The conclusion I come away with is that if you don't know what will
definitely work, plan on experimenting a bit with rod samples. There
are also other specialty rod companies besides Stoody (such as
Certainium). Keep reporting your results to this forum!

Here is an anvil thread from early last year.....
Subject: Re: old anvil
Vince and all other anvil lovers,
Double check your anvil, it should read Peter Wright, England,
Warranted, although the name of the company was Peter Wright and
Sons, during the later part of othe 19th and early part of the 20th
century.
If it is Henry, you probably have a unique Anvil, for there is no mention
of a Henry Wright anvil in the literature I have. Take your anvil out in the
sun, tip it, for good lighting, and have another look. If still not sure, do a rubbing.
The "130" is the weight, 1=112, 3/4 of 112 = 84 and 0=0, The anvil weights
196 lbs.
Brief history and dating of Anvils in use before the Hay-Budden in 1886.
Before 1650, made by local smiths
1650?-1850?, made by Mouse Hole Forge in Dudley, England
1850?-1886, made by Peter Wright in England, first at Dudley
1850?-1886, made by the Wilkeyson Forge in Dudley, England, following the
Peter Wright method of the six piece then a three piece anvil (more on
these next time)
1842 OR 1843, the first Anvil was made in America by Mr. Mark Fisher, and
later produced under the name of Fisher & Norris. "Eagle" brand.
In 1864 James Chase got out his first batch of two-piece American Wrought
anvils, 12 in all.
In Sweden, the Soderfore Bruke Aktiebology, founded in 1250, sold a one
solid piece anvil in 1885, sold in American as the Paragon.
Next time more about the building up process of the Mouse Hole and Peter
Wright Anvils.

Secont part of Anvils and more Anvils, but first a answer to the above.
This anvil was either forged or given a major repair job by the
Columbian Anvil & Forging Co. All their adds from 1906 to early 19
