Andrew asks, "I know its a silly question but is there a recommended length for the handle on a 3lb cross peen hammer? The one I use has a short handle, the one I just picked up has a long handle, both work fine but I find myself holding the new one half way down the handle."
It is NOT a silly question.
People that "push" the hammer use a short handle. People that swing a fast finger tip balanced hammer use a long handle. Novices using too big a hammer for their strength and skill level choke up on the handle. If you are using a power hammer or doing relatively small work you don't need a 3lb (or 4lb) hammer. 2 to 2-1/2 is better.
Pushing the hammer will end up giving you a bad elbow problem and cut your smithing carreer short. Some folks manage to do it a long time but it is problematic for most of us and tendonitus is likely. Practice hammering with the hammer balanced between thumb and forefinger. Use velocity, not brute force. When your arm gets tired quit before you hurt yourself. I recomend starting with a small hammer (18-24oz) and working up.
There are a lot of very good smiths that have developed the strength to push a heavy hammer using short strokes. Some full time smiths can get away with this but they are rare. This is a subject that many have a distinct opinion on and the arguments can be endless. However, physics says a small fast hammer can perform the same work as a large slow hammer.
My personal technique varies between swinging when I am fresh and pushing when I am tired (when I should quit). I also use a loose sliding technique where I let the hammer almost leave my hand at the top of the stroke to grab it at the very end for speed and then change position near the bottom of the stroke preparing for the next swing (result of too many years using an axe). This is tricky and I would have to hunt up a lighter hammer since I have spent way too many hours at the keyboard recently!
I also like to use common "factory" hammers as they are easy to replace. However, I think I am going to start making my own straight peen hammers with a smooth ovoid peen. Just an idea I wnat to try. . .

Guru, Do you know of anyone who is selling scrolling forks? Several welders have told me that they bought theirs through a catalogue but they can't remember the name of the company.
Bill -- applecross1 at msn.com Monday, 08/17/98 00:42:06 GMT
Scrolling Fork (Bill): I looked in the Centaur and King Supply catalogs and didn't find anything. Centaur may have carried them (or DO and they aren't in the current catalog). They have everything else!
I always made my own. Since I scroll hot I make them out of mild steel. For cold scrolling I would use material from an old wrecking bar (3/4 hex SAE 5160). Cut, bend and weld a second "finger" on. Some of my mild steel ones have had the handle end drawn out with a ball end. Tapering them makes them lighter for the length AND adds length for leverage. The fingers should be no longer than needed for strength (about 1-1/2" Max). The welded on finger should be upset to produce a robust joint. I arc weld mine but they could be forge welded as well.

David B. asked in the prior archive, "I have found a good supply of L7 steel and l'm not sure what the best method of heat treating it is? I understand it has Nickel in it. Any ideas would be of great help."
L7 heat treatment is not listed in my ASM Metals book but L6 is. These alloys are listed as Low-alloy special-purpose steels. And L7 is listed as a steel no longer in use.
L6 is heated slowly and hardened at 1450-1550F. Oil quenched and tempered in the range of 350 to 500F.
L7 is listed as a very high carbon steel with a full 1% Carbon. .4% Mo, 1.40% Cr and .35%Mn. As a super high carbon steel it probably needs to be hardened at the higher end of the scale or a little more. Say closer to 1575F.
This very high carbon content means that the steel must be handled carefully and can be tempered to a wide range of hardneses.
Sorry it took me a while to get around to this. My ASM Metals Reference Book was burried in the van. . .

Hi i got your site by Rick he send me here ... and he says that you can answer to me question better than he ...
I'm totally news in blacksmitting ... but if that can help you to make your mind ... i've built my own forge with a brake drum !!! dont laught that work well ... but i need to know what kind of combustible i had to keep a warm fire and also what kind of metal i can use to forge a sword ... cause i'm a medieval maniac ... and i know is more than one type of metal to forge a sword so name me two or tree who is good too ...
tanks ... and i wait to your response
Jonathan Boulay -- xsoldier at globetrotter.qc.ca Monday, 08/17/98 04:28:05 GMT
Jonathan, Brake drum forges are a good place to start but you may need something bigger (or at least longer) for making swords. Bituminous or "soft" coal is what you burn in most forges. Ask for stoker or "nut" coal. I'm not sure if they call the sizes the same in Canada but that is lumps of coal from 13mm to 50mm. Some places sell it as "blacksmithing" or "metalurgical" coal.
For practice you should forge your first sword(s) from mild steel (SAE 1018 - 1020). It is easy to work and is suitable for SCA style mock battle. It will not hold an edge very well but that is why it is practice material. You will need lots of forging practice before you make a good looking sword.
Old automobile springs can be hardened and tempered into a fine sword. You can use leaf (flat) or coil (round) spring steel. Thin leaf springs from a small car like an MG make great knives, chisels and swords.
Classic medieval swords are made from several types of steel forge welded together. A low or medium carbon steel (SAE 1034 or 4140) for the center and a high carbon steel (SAE 1080) for the edge. You will need a LOT of practice forge welding before attemping this style blade.
THEN, There is the fancy Damascus (laminated pattern welded steel) blade. These are made with a fancy center section and a finer grained higher carbon edge. This is the highest of the art and may take years to achieve.
If your sword is mostly for looks and play, Aluminium can be sawed and filed to shape. It will easily take a mirror finish. A LOT of the swords you see in the movies are aluminium. Good alloys are 2024 or 6061T6.
You may want to read up on blacksmithing and then bladesmithing. I reccomend Jack Andrew's NEW Edge of the Anvil and Jim Hrisoulas' The Complete Bladesmith to start. Both are available from Centaur Forge. Ask for a catalog when you order the books and tell them I sent you.

Guru: That L7 looks a lot like 52100. Don't know the effect of the Mo. on the AC3, but if neglible, then the austenizing temp will effect the MS and MF temps.
grandpa -- darylmeier at usa.net Monday, 08/17/98 05:29:52 GMT
David (more L7): The AC3 is the transformation point or where steel becomes nonmagnetic austenite and hardenable. Ms and Mf are where martensite starts and finishes forming (hard steel).
52100 does look like L7 with out the Mo and is hardened at 1415F, much lower than the 1575F I stated. I was guessing at the higher temp based on the Tempil chart that shows an upward spike for steels with more than .85% carbon. In any case you want the point where the steel becomes nonmagnetic.
NOW, the ASM Heat Treater's Guide says 1550 to 1700F for L2 (L7 being a grade of L2 with high carbon). It also reccomends normalizing after forging and before hardening. After the quench it should not be allowed to cool below 140F and be tempered immediately.

Concerning Texas coal again.....the coal scuttle had Nick Brumder listed twice as a source of coal in Texas. I talked to Nick and he doesn't sell coal nor does he know where to get it. I have found two sources...in Conroe and in Azle, but both sell the PA stuff...would like to find better. Should I get a big truck and go to Tenn.
Ken Seabourn -- forge at bluebon.net Monday, 08/17/98 15:31:30 GMT
Coal varries from mine to mine and even seam to seam but PA coal is some of the best in the world. Thanks, I'll get the Coal Scuttle straightened out.
-- guru Monday, 08/17/98 18:22:07 GMT
As the guru says, PA coal is some of the best in the world. But what I use comes from W. Va. It's got a fair amount of sulphur in it, bus so does the PA coal. The coal at the ABANA conference in Ashevill this year came from the same supplier I get mine from.
Jim Wilson -- pawpaw at netunlimited.net Monday, 08/17/98 18:36:23 GMT
I get some great coal from The Coal Yard, that you all have listed under" Indiana" in the Coal Shuttle...W.Va coal.
Dave Curtis -- DCurtis176 at aol.com Tuesday, 08/18/98 01:35:40 GMT
In regards to my question on tempering steel. l'm sorry to say that l make a mistake when l sent that. lt is in fact L-6 steel. l'm glad you had me covered on both though. l'm currently using it to forge a wonderful Damascus steel with a great contrast between layers. l do believe that this is the nickel in it. Last nite l forged a blade of over 200 layers 22" long with 12 full twist in it. After surface grinding it and etching it l was speachless. On another note l've done Cable knives for friends and such but finding good cable sometimes is a problem. l had someone give me some 1" cable but is was rather rusty. l cut it into 10" pieces and then submerged it in Muratic Acid for 20 min. lt came out totally clean and ready to forge. Anyone having trouble getting cable might try this. Oh, make sure your cable is all steel and doesn't have a rope or plastic core in it!!.

I have been slobbering all over the idea of a powerhammer ever since I got to use one at a workshop. But I have a question. I am a sometime/partime knife and tool maker. Would a treadle hammer do me as well as a powered hammer? While I can't really justify buying a powerhammer (unless one of those deals-of-a-lifetime happens my way) I could probably build a treadle or a JYH (with a little help from my friends), so, in the considered opinion of the local community, which would be better for my purposes?
Thanks for all the help mid 70's and cloudy in Seattle
Geoff Keyes -- timour at conceptsnet.com Tuesday, 08/18/98 19:56:52 GMT
Treadle or power? (Geoff):
There is no substitute for power! A treadle hammer free's your hands somewhat but the POWER comes from you. It should be fairly easy to add Grant Sarver's JYH#2 mechanism to a treadle though. This pulls the helve down by momentarily engaging a piece of V-belt in a motor pulley. The design secret is, you need a spring between the belt and the helv so that you don't stall the motor with a suddenly applied load. Grant used bungy cords but a heavy screen door spring would work. A lever with a needle bearing roller was used to press the belt into the pulley. The pulley wants to be as small as possible and the motor could be anywhere from 1/3HP up.
As you can see I've got a connetion. It is somewhat tenous though. Some IO port conflict that doesn't seen to remain constant! DOn't ya' LOVE IT! :)
-- guru Tuesday, 08/18/98 21:49:15 GMT
Geoff: JYH is good too! I just thought I'd mention you can have both in one machine for flexability.
OBTW- DO NOT USE LEAD FILLED TREADLE RAMS. There is absolutely NO excuse for using lead. Steel is heavy, cheap easily cut drilled and welded and does not pose an envirmental risk. The whole LEAD WEIGHT mentality is DUMB! The Nuclear guys are just as dumb about it and keep using lead when they DO NOT NEED TO. Steel is just as good a radiation shielding too given an equal mass! Get the lead out!
-- guru Tuesday, 08/18/98 21:56:37 GMT
Grandpa, to answer your question about the twist. l've never had a blade twist during heat treating. l understand you make Damascus, might l share with you and others a trick that works very nice to do twist work. l got an old powervise from a friend of mine. You know they use them to thread pipe. Make sure your piece is very hot and then insert your piece and hold the end with a pipe wrench and hold on when you hit the switch.
David B -- Outrage806 at aol.com Tuesday, 08/18/98 22:40:02 GMT
David, grandpa (Daryl Meier) not only makes Damascus he's really IS a legend in the field. His production of the "George Bush Bowey" presentation knife proved that certain blades that were considered almost mythical could actually be made (the blade had the American Flag with ALL the stars and stripes and "USA" repeated 13 times (I think)). It had been over 170 years since Degrande-Gurgey produced a similar feat in 1817. Daryl was a member of the "Damascus Steel Reesearch Team" with Jim Wallace and Robert Griffith in the early 70's at the Southern Illinois University at Carbondale. To say that grandpa "makes Damascus" is quite an understatement.
I expect he asked about twisting because the different materials in the laminate shrink differently when hardened. The tension tends to cause blades to twist either durring hardening or tempering unless the forces are very carefully balanced.
Power twisting is good, however I recomend that the work be clamped while twisting. Holding on to a wrench attached to a machine that produces thousands of foot pounds of torque is very dangerous! If you try a piece too big or let it get cold you will be in big trouble. The machine should also be wired with a "dead man" switch so that when you let go it stops.

-- guru Wednesday, 08/19/98 00:10:26 GMT
!YEAH! I just love this lead filled hammer stuff. If it's so great for forging why don't they use a lead filled hand hammer? The ancient Greeks made their plumbobs from lead because they thought it hung straighter!!! Their name for lead was plumbum that's why it's chemical symbol is Pb, hence plumbob and plumber, not to mention plumb stupid!
GRANT -- NAKEDANVIL at USA.NET Wednesday, 08/19/98 00:20:11 GMT
I gave my opinion on the power vs treadle hammer over on the Junkyard, so let me just re-iterate here that I agree with the guru and with Grant.
As far as lead goes, I've got several hundred pounds to make into fishing weights, if anybody wants them. But it ain't a hammer, no rebound! Hammers made with lead or lead shot filling are called "dead blow" hammers for a reason.
Jim Wilson -- pawpaw at netunlimited.net Wednesday, 08/19/98 01:33:55 GMT
Scrolling Forks. Get an old grader blade from local highway dept. , constuction co. , or scrapyard. cut out wanted shape of forks with torch and leave enough on end to draw out for handle. clean up around forks with grinder and file. flatten handle a little to give more control and strength. with normal use, hot or cold, it will outlast you. Smokey.
Smokey Wednesday, 08/19/98 03:01:51 GMT
GURU: You expected exactly right about my question to David. In a twisted laminated bar the expansion/contraction/transformation forces are running diagonally across the bar and in the OPPOSIT direction on the other side!!! Impossible to harden without twisting.
grandpa -- darylmeier at usa.net Wednesday, 08/19/98 04:59:30 GMT
I recently aquired a forge and hand cranked blower from my local junkyard and was wondering if anyone has any information on it. The blower has listed on it CANEDY OTTO MFG CO CHICAGO HIGHTS. It may have been used for railroad work(just a guess) any info would be appriciated greatly. Of course the best part is I picked up both the forge(little or no repair needed) and Blower for just 15$!!! They didn't know what they had!!

Jock: the anvil of my power hammer is hollow, (remember its only a prototype at the moment) i wanted to deaden the ring/reverb when the hammer hit it.. Rather than fill it with LEAD how about sand :) or oil? just a thought... the next unit will be solid!. hmmm theres an idea, hollow hammer, low transportation weight, when you get to the destination fill the sucker with oil or water. and away you go, when finished just purge the liquid and you have a light habber again...

Still looking for good coal in Texas...but this time I do have a tech question. I have an old 25 lb little giant, broke the spring first time I used it...replaced the spring and installed a quard. Tried to adjust it but it still does the hula occasionally. My question is...would installing a shock absorber in there somewhere take some of the convulsions out of it?? Thanks
Ken -- forge at bluebon.net Thursday, 08/20/98 02:55:21 GMT
What'sa "quard"??? Does it do the hula when you're forging hot iron, or just when you run it without any work in it? This is a serious question, I've seen people dry fire a hammer and condemn it because it dances, yet the hammer actually works fine with hot steel in it!
GRANT -- NAKEDANVIL at USA.NET Thursday, 08/20/98 03:33:31 GMT
Grandpa, While l have read your input on this page l have never looked at your E mail address. Had l looked and seen your name l would have known you, "Grandpa" just didn't turn the light on. l've seen your work and have seen pictures of the blade with the flags. l respect your work and admire it. But are you saying that all twisted blades twist? Granted, l've had my share of heat treating suprises. But on blades of 8" or less l have had no problem. l've made pieces up to 24" but haven't treated because l didn't have a forge large enough to take them to temp. l do however do something to my steel during forging which no one else has told me they do or have l read of anyone doing what l do.
One other thing for the Guru, you spoke of a way to start and run 3 phase motors with a bank of capacitors? is there any way you can send me a drawing of this setup? or if anyone has a drawing of just how a 3 phase convertor works send it to me. My father built electrical panels for 30 yr in a steel mill but he needs a drawing to understand "just what their doing in that box". Seems that ever electrican l talk to says the same thing, "l know you can do it, just don't know how" Can anyone help?

I've been asked to braze a brass fitting for an old car at Ft. Edmonton. Is there a proper way to do this? I'm assuming the brazing rod melts at a lower temp than the brass, I wouldn't want the whole thing to turn into a puddle. ;-)
Doug Hall -- dhall at compusmart.ab.ca Thursday, 08/20/98 14:56:32 GMT
Guard..excuse the typo. And for other beginners (in blacksmithing) such as myself, the springs in little giants do break. And no, I do not "dry fire" a hammer....
Ken -- forge at bluebon.net Thursday, 08/20/98 17:45:01 GMT
Wasn't trying to be mean, couldn't figure out what your typo meant to say. Also I like to look for the simple answer first. If you believe you have the proper spring then you may need to adjust it tighter, after each adjustment you should lower the ram so the dies are about 1" apart. Guides should be free but not sloppy. Good luck!
GRANT -- NAKEDANVIL at USA.NET Friday, 08/21/98 01:53:40 GMT
IN SEMI REVERSE ORDER:
LITTLE GIANT HULA: Sometimes it can be adjusted out by playing with the stroke. Grandpa's comment about "dry firing" the hammer can be related to improper stroke (work height) adjustment. The spring preload can also sometimes be a cause. The spring should be tightened until the toggles are nearly horizontal. My opinion has always been that LG over rated their hammers and ran them too fast. Those setup to run slower than OEM specs tend to hula less. I've also found the hula to be related to variable friction. Keeping the guides well lubricated helps but changing lubricants can sometimes cause trouble by causing more friction (typical of heavy grease or sometimes new grease OR grease cooling off). Oil generally works better on the guides than grease. Most LG users eventually get a feel for their machine and it stops doing the hula. This is likely "touch" on the clutch or forcing the machine to run slower. My study of the JYH shock linkage indicates it adding a damper in the LG linkage would probably make the problem worse. The JYH shock linkage does a similar (less destructive) thing at high speed and stops when run slower.
BRASS: Brasses melt pretty close to the same temperature. You can weld most cast brass with an oxyactylene torch using brazing rod as a filler (all close to same melting point). Its a little tricky due to the high thermal conductivity of the part but it can be done. A safer way to make a repair on a brass part that you may not want to actually melt the base metal is to silver solder it. Commom silver solders come close to matching brass in color but will be brighter with time as the brass oxidizes faster and darker than the silver/copper alloy.
ANDREW! HAPPY BIRTHDAY OLD MAN!
Lead is a good sound dampener but it STILL enviromentaly bad! In hollow vehical drive shafts that but a close fitting cardboard tube inside to stop ringing. Dry sand would would work. The Old BLue and BIG Blue hammers have places to fill the frame with sand to prevent ring and add cheap mass. Oil would be messy and possibly dangerous. Water might be a rust problem.

GRANT: Thanks for the adjustment tips!
3PH INVERTER: I have that info but currently have limited graphics capability from this location. A three phase motor can be used without capacitors by starting it with a manual starter (pull cord or small motor). The 3PH motor "inverter" is brought up to some minimum rotational speed and then the power turned on. The "inverter" is wired to single phase 220 and smaller 3PH motors wired to the three legs of the "inverter". Capacitor types are wired the same except that capictors are installed between one of the single phase legs and the "generated" leg. These start when power is applied but sizing the capacitors is a trick. Several years ago Fred Holder ran a series on motor/inverters. Maybe we could talk him into letting us rerun it on the net!
TWISTED "DAMASCUS": Except for recognizing the why of grandpa's comment on the twisted blade warping problem I have no experiance in the field and will defer to those of you that do!
-- guru Friday, 08/21/98 03:03:08 GMT
David B : Yes, all single bars of laminated damascus, when twisted will twist passing through the transformation temperature. This occurs when cooling from forging temp., when annealing, and when hardening. AAAAAH warm days and cool nights in the heartland!

I am new to blacksmithing and have just been given a very old anvil. I am trying to find out what a 1849 William Foster 118lbs anvil is made of. I want to repair the horn which is missing. I'm not even sure if the anvil is worth repairing.
Thanks for the help.
Mark Stevens -- alflower at scott.net Friday, 08/21/98 03:24:37 GMT
For whatever its worth to the guy that asked the question. I just finished brazing some cast bronze finials to some scrolled 3/8 "mild steel and it's a bear because just as the rod gets hot enough the base starts melting away. I found that it helped to put a little extra flux between the two pieces and on the surface and start applying the heat to the rod just as the extra flux "glosses off" and play the heat on the rod. Also hope the coustomer doesn't bump the finials to hard:).

Hey Jock what's the best way to forge arrow heads the type with four edges or should I weld them together and hammer finish them.Got any suggestions, let me know. Hey Grant I finally got to see some of your work. Looks really great.
Ya all take care Rick
Rick -- rickyc at Friday, 08/21/98 06:57:52 GMT
Mark, I think That William Foster anvil was made in Wales. Jim Wilson will probably have something to say about it since he has one. They are very good anvils. I'm told lots of anvils were "destroyed" during the American civil war by notching the horns and breaking them off! No fault of the anvil. . . Do not have confirmation on this story.
Body should be wrought iron. Can be welded like steel except the impurities in wrought tend to do funny things and sometimes it acts like foam metal when arc welding and undercuts very bad.
WELDING THAT BRASS: Like I said "tricky". I use a lot of torch movement once the bass metal is hot enough. Melt a little rod in and wave off the torch while the puddle cools just to freezing and then weld a little more and wave off again. Takes concentration and mhaving your face in the work. Forgot to mention the borax flux which is a bitch to remove afterwards. Silver solder flux is worse though.
Arrow Head? Four sides? Not sure what shape you are speaking of Rick.

IF that William Foster anvil was made in Wales, it's PROBABLY a good anvil. I don't know that I'd try repairing, or replacing the horn, though. Might just grind the area where it was flat and use it without a horn. Jock can tell you more about how to repair it than I can. The body is probably cast iron, but no way to tell at this distance for sure. I say If, because mine is a Griffiths anvil, not a Foster. The deciding factor (for me) in determining whether to repair or not would be ring. If the anvil has a nice ring, I'd look seriously at repairing it. If not, I wouldn't bother.
Steel is cooking, what else? :) Just finished a small order for a decorator, got another order from the same source. If you're trying to make some "razor blade" arrow heads, cut the half shape from small mangle iron and weld the halves together. Then hammer finish and sharpen.
Have a safe trip, and take LOTS of pictures!

Jock, was looking at your 20 ton press with dieset for punching 3" candle drip pans from 16ga steel. I have a lady who would like some copper drip pans about 2 1/2-3" for a lamp I made for her. Is 20tons necessary to punch copper flashing which is what Id probably use. I have a regular 12 ton hydralic press but no dies so guess I'm stuck with the old reliable tin snips but only need 3.If I want to put together a press for "production" work, how massive does a press need to be to punch copper vs sheet meatal? Any ideas appreciated bruce

Cutting RR Track with a power hacksaw is not a problem. Just line up the cut and start the saw. I've cut a lot, have several 1/2" paper weights laying on the desk as I type. I don't anneal, normalize, or anything else, I just cut it.
The swage block? Depends on how bad you want it. Considering the condition as you describe, I wouldn't give more than $20 - $25 US for it.

Grandpa..Just finished welding, twisting and drawing out a piece about 10" long, made from worn out hack saw blades and metal banding material. I made about 4 twists per inch. After reading about the *twisting* during the heat treatment and quinching, I'm wonderin how much trouble I will have keeping it straight. I have only made ladder patterns before this first twisted one....worried about the outcome..can you give me some info on how to deal with the stress I have created in the material...When I finished, I brought it to a low red heat and it is in the ashes until morning..wont this relieve some of the stress?

Anybody have any direct experience with the Henrob torch? I'd much appreciate hearing about it, especially as to cutting stainless, brass, aluminum, welding, brazing same. I have called their 800 number, received their brochure, seen their website, find them lacking in the sort of specific info one finds in other welding equipment manufacturers' catalogs such as Lincoln, Miller, Harris, etc. All they state directly is that it will cut one inch mild plate. I'm interested, but for $320 plus change, I want some facts. All replies strictly confidential and off the record, word of honor. Many thanks.
John Neary -- jneary at roadrunner.com Sunday, 08/23/98 04:47:27 GMT
Randall: If it's twisted in the morning-- straighten it( I use a vise and crescent wrench). If it's twisted after hardening, temper it at 50 degrees f lower than normal. Then clamp between two straight plates, and shim if nesessary till it's straight. Then temper at the regular temperature. If still twisted, repeat clamping and tempering untill straight. There are several factors involved in the twisting phenomenon. Difference in the mechanical properties of the steels used being the most important. Twisting will vary from very slight to extreem. Good Luck.

Grandpa..Thanks for the info. I checked it this morning and found it to be straight..whew,,,relief.And I over estimated the amount of twists. It is more like 2.5 to 3 per inch, and only about 8.5" long. I suppose ther is still the possibility of warping during the heat treat, but your advise will help me get through that..thanks for sharing your vast knowledge.

Punching Copper(Bruce): Copper flashing will punch easily at 12 tons in the diameters mentioned. I could do the calcs for you but its late and I just got back from PA. Just don't try to run 16ga steel in the same dies! You can order dies from Roper-Whitney but even though they will make them AFTER you order them and you tell them they are for blanking, there is a good chance you will get a punch with "shear" built in (like electrical K.O. punches). The last three sets I ordered can that way and I had to grind off 1/4"! If you need help on making the dies we could get into that later. OR you could have me punch the blanks for you. My dies are 2-1/2" round.
Cutting R-R rail (dimag): If the top of the rail looks heavily used work hardening can be a problem. Otherwise a first class blade kept oiled with kerosene or cutting oil should last for dozens of cuts. Run the saw on its lowest speed (if variable) for stainless, alloys and high carbon steels. I've found the high priced welded HSS/with soft back blades to be more cost effective for sawing than plain carbon steel blades.
$WAGE BLOCK: Just came back from PA where I saw blocks for $100 to $350. It all depends on how bad you want or need one. Small new ones
start at $85 + shipping.
Henrob Torch (John): I'm still kicking myself for not siting through a session with them at Asheville but hope to see them soon. Yes, I agree that the information available is a little thin. I believe the cutting of non-ferrous materials is for light sheet stock. I CAN testify that it is GREAT for cutting steel. It produces a very fine kerf and can be used for very intricate cutting.
Blacksmithing Schools (Randy): Try the ABANA site (see the links page) for schools. If you don't find one close by try the ABANA chapters list and contact the closest chapter. Many of the chapters hold semminars, demonstrations or classes. If these fail I can but you in touch with a fellow in Oklahoma City that may be able to help you.
Thanks for the Phase Converter info Greg!

How does someone who knows absolutely nothing about blacksmithing get started? Are there courses available and, if so, how could I find out about them?
Lisa Osse -- losse at ch2m.com Tuesday, 08/25/98 00:32:29 GMT
Getting Started (Lisa): Today you have a lot of options for getting started in blacksmithing. Try the ABANA (Artist Blacksmiths Association of North America) web site for membership and schools information. There are numerous blacksmithing schools and ABANA can also help you find local blacksmiths through their local chapters. Many of the chapters also hold workshops and demonstrations. Although ABANA is a U.S. organization they have chapters in other countries and their counter parts too.
There are several chapter conferences coming up soon. In September there are at least three that I know of. The Alabama Forge Council (see link from the anvilfire NEWS), Mid Atlantic Blacksmiths on 9/12-9/13 in Dover, DE and the Quadstate Round-Up in Ohio the following weekend (I think). The first two are significant gatherings of blacksmithing talent. You could learn more at either of these events in a few days than in years of self study. If you are serious about learning blacksmithing, either of these would be worth taking a few days and attending either or both.
I have an article posted under 21st Century called Getting Started that may give you a starting place or two.
AND there are many books on the subject that can be very helpful. I mention a few in my getting started article. Alex Bealer's Art of Blacksmithing is a classic on traditional tools and methods. Jack Andrew's NEW Edge of the Anvil is one of the best all purpose books including both how-to and technical reference material. There is a review of his book on our Book Shelf page. Even if you go to a blacksmithing school(s) you should have these as references. If you order either of these books from Centaur Forge, ask for their catalog. It is a blacksmithing education in itself and they sell other books on the subject including many on specific specialties.
Besides the schools listed by ABANA many college art departments have metal scultpure classes that may include many of the skills I recomend in my getting started article. Some have anvils, forges and heavy machinery available. Start local and ask pointed questions before signing up.
Let me know if you need more specific direction. You've made a good start by finding anvilfire and the community of blacksmiths on the Internet.

SOME NOTES FROM BILL PIEH, Centaur Forge
First off, I like the Canedy-Otto equipment better than Champion and Buffalo. This is especially true of the hand-crank blowers. If one were to examine all three brands you will note more precision in design and worksmanship on the C-O blowers and their gearboxes. Unlike the competition, the C-O units will hold oil and the pinion (impeller) shafts are not located in the crud sumps in the bottom of the gearboxes where all the dried glop and broken gear teeth
wind up in the buffalo and champion units.
As for 3-phase converters, I do not like static phase converters and prefer the rotary phase generators. The static phase converters are just a box of relays and capacitors that fool a motor into thinking it is starting on 3-phase until it gets going and then the relays kick out and the motor is only running on single phase with very poor efficiency. One must remember that a 3 phase motor has three sets of windings that is powered from three hot wires. ONCE ONE HOT WIRE IS TAKEN OUT, all the power is going through one of the 3 windings. This is hard on the motor and very inefficient. A rotary phase generator generates true 3-phase power and the better designed commercially made units (such as the Arco) are about 95% efficient.
I'm not sure about Bill's comment about the static inverters but I know the rotary type are pretty good. I have a 10HP Arco unit and have studied its operation pretty close. Although they DO produce pretty good three phase power you have to pay attention to which circuit you put magnetic contactors in. When a second motor is started on the circuit a contactor (coil or solid state circuit) wired to the generated leg will drop out due to the voltage drop. The bigger units also tend to vibrate and can be VERY noisy. I got mine because the shop that had it couldn't stand the noise! It is currently not installed but I plan on putting it in an outdoor shed to keep the noise out of the shop!
-- guru Tuesday, 08/25/98 02:44:52 GMT
Grandpa has an ARCO 10 hp rotary unit, and it is noisy! They are good units but do not make exactly 3ph power. One leg is high, and the phase angle is not quite the same as line voltage. Still perhaps the best choice for those of use that live in the boonies. Hot days and cool nights in the heartland.

Copyrights are for printed matter ONLY! Guess it's been extended to include software too, but not iron work. You can get a DESIGN PATENT for a unique design, but design patents are very hard to enforce. Your best protection is a well executed design at a reasonable price.

COPYRIGHT: Wrong Grant! Sculpture and works of art can be copyrighted. The Library of Congress handles copyright matters. However, unless your work is VERY distinctive and would have to be copied by making a mold of it you are probably wasting your time. If I can look at it and make a similar item without making an exact copy your copyright is not worth much. AND in the end ALL patents and copyrights are only worth what you can afford to persue in court. However, IF you have a registered copyright, the infringer is automaticaly libel for your legal fees. Your local library is a good place to start. The LOC also has forms on-line.

POWER HAMMER DIES (T.J.): The right material is largely dependant on the use. General purpose dies can be made from medium and high carbon steels. H-13 is one of the best steels as it is an air hardening hot work steel. However, it is expensive and not the easiest steel to work. H-13 is available in a pre-heat-treated condition that is just barely machinable but hard enough for dies. The trade name is Viscount 44 by Latrobe Steel. SAE 4140 or 4150 is a commonly available medium carbon steel that has been sucessfully used for hammer dies. RR-rail and axels are often made of 4140-50 I'm sure Grant and some others will have some suggestions and comments on this question.
Although it is commonly done in industry, I don't recommend build up repair on dies of unknown material. However, you can do wonders by grinding them. If you want them to be really spiffy have them ground on a surface grinder and then dress by hand if need be. Most power hammers have a lot of room for adjustment and can compensate for relatively big changes in the dies.
On the practical side. I have personaly used and also seen others use mild steel for medium production specialty dies (up to multiple thousands of parts). Mild steel dies can be used for making tenons, tapers, balls and top rail among other things. They are easy to make, do not require heat treatment and last a long time as long as you are careful to forge hot steel in them.

Can anyone out there identify an anvil of cast steel w/ cast-on face, American pattern with no markings other than a roughly 1.5-2" dia. raised "W" on one side (part of casting). Rings like a church bell - unbelievably clear and deep, carries a good while. I haven't weighed it yet but it looks to go + or - 240#. Also, old leg vise of wrought (grain obvious in leg) with small six pointed star containing the words "Iron City" on one side. On a different note, I've been doing lots of work with iron for the last few years but it's so darned expensive(new English). How can I tell if old rr track is iron - i.e., are there any dating guidelines? Or, if I give in and move to 1010 or 1020, are there any truly nasty fluxes that can be used that will essentially allow me to scarf weld like I do with iron (no flux, or sometimes borax) without worrying about scale buildup over many heats? Boy, if I throw any more questions out there I'm going to knock someone over. Any help most appreciated.
Eric Kettenburg -- theland1 at epix.net Thursday, 08/27/98 04:16:03 GMT
Reading over the copyright law is very interesting. Covers more things than I ever thought! Actually does appear to cover the design of forged articles. Not USEFUL items though! You must separate the useful part from the art. Useful comes under patent law. Courts regularly use the "reasonable man" theory in matters as subjective as design. Small variation can't be used to circumvent the law, in other words, if it walks like a duck and quacks like a duck, it's probably a duck.
GRANT -- NAKEDANVIL at USA.NET Thursday, 08/27/98 05:25:33 GMT
Pretty rare nowadays to find iron rail. It was the demand for STEEL for rails that created the steel industry and that was over 100 years ago. After welding real iron for years you will find anything else to be little better than a good paste job.
GRANT -- NAKEDANVIL at USA.NET Thursday, 08/27/98 05:35:06 GMT
Thanks so much for helping out, Grant. So: the logical next question would be, if I stick with iron, where the heck can I get it other than the RWI Co. Seems like he's got the market cornered! I've used old bridge iron, but it was pretty *#$ at & to work with - I guess the rust typically penetrates into the grain and eats up the slag. Working with that stuff seems akin to pulling absessed teeth with a pair of hot tongs. Are there any good books out there that are useful for old anvil, vise etc. identification?

TRIANGLES (musical or dinner bells - dimag):
Although small musical triangles SEEM to make a sweet clear tone all triangles make a dissonant tone (many overlaping frequencies not necessarily in sync).
Hard triangles work better than soft but I found all I needed to do was quench the mild HR bar immediately after bending. Hard corners seem to do the trick and 20-30 point carbon steel is good enough.
Shape and proportion makes a HUGE difference in triangles. I always made a tuning fork variety (three bends, open ends facing each other). After making a triangle from 1" wrought iron that was a complete failure I made a short study of the subject. I experimented with a LOT of proportions. In the end I found a 30" length of 1/2" HR made my "Best Ringer Ever". Bends were at center and 5" from the ends with about 1/2" betw. the ends. If you make this one I'd appreciate credit for the pattern!
-- guru Thursday, 08/27/98 22:20:52 GMT
In your response about powerhammer dies,you talked about using 4140 or 4150, should this be heat treated or not?
Mark Damman -- ddamman at mail.k12.ks.us Friday, 08/28/98 01:15:29 GMT
SAE 4140/50: All general purpose tool steel dies should be heat treated. 4140 can be oil or water quenched but oil quench is safer (less likely to crack or distort). The pre-heat treated H-13 (Viscount) is an exception. It is designed to be used as-is.
FORGE WELDING MILD STEEL: All the forge welding I've seen and done was with borax except the one occasion I saw red clay used. I HAVE seen mild steel forged without flux. The requires exception coal and skill. Jim Hsirosoulas recomends borax with 10% flourite for laminated steel work. This IS the nasty stuff you summised existed. Wrought iron has the advantage of being able to be worked at slightly higher temperature without burning but scaling problems in mild steel are a fuel/air mixture problem.

STARTER EQUIPMENT (Wes): Its great that you are getting out and doing it!. Just keep going the direction you are going and you will do just fine. Don't listen to those that say you need a special this that or the other. I DO recomend you pick up some reading material such as Jack Andrew's NEW Edge of the Anvil (See my review on the bookshelf page).
Look under Plans for directions on building a brake drum forge. It may be more convienient than what you are currently using. That leaf blower probably produces too much air. A forge fire only needs a gentle breeze to bring it up to a white heat. Too much air causes a lot of scale (that grey flakey stuff) and burns the steel.
On the 21st Century page, look under anvils. There is an article on a cheap anvil substitute. Almost ANYTHING heavy and made of steel or cast iron will do for starters. Cast iron will chip and eventualy crumble but is commonly available as engine blocks and heads. The older the better (heavier). Some people use a short length of rail road rail but this is often harder to get than one would think AND is very springy. If you find a piece or rail, bolt it down to an old engine head and bolt both to a stump (wood block) or stand. The rail will give the hardness and durability and the head will provide the mass. Stuff like "I" beam looks like it would be a good anvil but most is too springy. An anvil needs to have compact mass.
Almost any kind of hammer other than a carpenters claw hammer is suitable for smithing. Don't start too big. For your age 2lbs should be about the max. Many smiths like a ball pien or "engineers" hammer. Regular smithing hammers are available at most hardware stores.
For tongs, channel lock pliers work great and so do ViseGrips (they were invented by a blacksmith!). Regular tongs are better because their length gives you more leverage AND distance from the hot iron. I have a fairly easy method of making tongs posted under 21st Century. These should be made from mild steel. Your first pair may take you a day or two! However, it is good practice. An experianced smith can make a pair of tongs in less than an hour and Peter Ross (the head blacksmith at Williamsburg, VA) can make a set in 10-15 minutes!
MATERIAL: Most of us start with scrap and rapidly move on to buying our steel from metal suppliers. Old fashioned "wrought iron" is only available at high prices and used very little. Almost ALL general smithing done today is done using steel. "Mild steel" is low in carbon and is what most decorative work is produced in. Technically it is called SAE 1018 or SAE 1020. Structural steel (that used in buildings) is called A-36 and is nearly the same thing. Long pieces are hard to find as "scrap" but you might ask a welding or machine shop if they will sell you some. Hardware and hobby stores sell short lengths (about three foot) but you pay for the convinence. 1/4" and 3/8" square are good sizes to start with. 1/2" square and round is what most smiths make fireplace tools and such from.
SCRAP STEEL: Like automotive springs, axels and shock absorber struts are generaly high carbon steel and are good for making tools such as hammers, punches, chisles and anvil "set" tools. A good friend of mine makes all his hammers from truck axels and many of his hot work chisles form McFersson strut rods.
Check out the Centaur Forge page for what blacksmithing tools look like (it is currently under construction with additions weekly). Order Jack Andrews' book from them and ask for a catalog. Although they sell a lot of farriers tools they also have almost every blacksmith tool available and lots of other hard to find books.
Let me know if you need more help!
-- guru Saturday, 08/29/98 14:24:14 GMT
GASOLINE ENGINE POWERED HAMMER (Doug): Its been done before and works pretty well. You need an engine that has a govenor in good working condition so it runs at relatively steady speed and doesn't over-rev when the load is taken off. Most of these engines produce their peak HP at about 2000-2500 RPM. Check with the manufacturer and then use belting to reduce the speed accordingly.
If you have a good govenor then you may wish to connect the throttle to the hammer's clutch treadle so that the motor revs up just as you start to engage the hammer. Use a light spring for the connection.
Consider mounting the engine out doors and running the hammer on a line shaft. This will keep your shop quieter and move the toxic exhaust fumes outdoors. You can also run other machinery from the same line shafting!
If you are looking at the EC-JYH shock absorber hammer please note the following. A 40# ram probably needs only one shock. I increased the dual shock model to 65# and I think it needs a little more. 120-140 RPM (SPM) is all the shock linkage can stand. Otherwise the ram "floats". The tubular "dust cover" should be removed from the shock OR a shock without a cover used. The covers are not well supported and do not like the side shock. They will eventualy crack and fall off. Also note that this hammer has a completely different character from other hammers. It starts and ends with closed dies and hits with roughly the same impact each time. It doesn't hit as hard as the ram weight indicates but does have excelent control.

ONLY 4 DAYS LEFT!
It HAS been a HOT dry one for most of us. Where it hasn't been dry its been flooded. Hope things get back to "normal" soon!
MOST COMMON INCORRECT CONTEST ANSWER - Tree stump, made by God.
SECOND MOST COMMON INCORRECT ANSWER - The Bickern or Stake anvil.
The stump is supporting the blacksmiths anvil therefore it IS a piece of his equipment. The Bickern is a truely wonderful antique most likely made in England in the 1700's (manufacturer unknown) and imported to the U.S. Like anvils, they were used by many crafts, not just by blacksmiths. However, when in a blacksmith shop it WAS a blacksmiths tool and WERE very common a few centuries ago . . .
The answer to the contest is. . . difficult! But it is NOT a trick question! You still have time to enter.

Mac Brown -- macbrown at tcel.com Sunday, 08/30/98 23:09:17 GMT
Looks to me like "most" blacksmiths use any thing that will harden when quenched, some even use steel that doesn't meet that meager test!
Next best is probably steel from springs known as "spring steel". What do ya think the mills make durring the other three seasons? Choise is probably S-1 tool steel, this being the closest thing to a "one for all" tool steel for blacksmiths.
GRANT -- NAKEDANVIL at USA.NET Monday, 08/31/98 01:10:29 GMT
S1 TOOL STEEL (Mac): The steel Grant recomended, S1, is a shock resistant (S) tool steel. It is oil hardened at 1650-1750 F and tempered at 400 to 1200 F depending on the hardness wanted. Before quenching it should be heated slowly and held at temp for 15-45 minutes. Double tempering is recomended for all tools seeing hard usage.
As Grant mentioned, modern smiths use what ever is handy. The fact is that for certain hot work even mild steel can be used. However, for durability some type of high carbon steel should be used. The advantage of the alloy steels is that they can be more resistant to heat (not loose their temper) than plain carbon steels. They are also generaly stronger.
For hot punches a heat resistant (H) steel is recomended. H-13 and H-21 are recomended. Air quench is recommended for these steels although some are oil quenched. A salt bath can also be used for a quench with less severity than oil and it can also be used for tempering.
There is a "best" steel for almost every application. But having hundreds of steels in a small shop is too expensive and complicated a system to maintain, so we compromise. We find steels we like, are obtainable and we learn to use them. Then we apply them to a wide range of applications. My personal favorite is whatever is lying around in the shop or left over from a job!
