If you Google "multimachine" or go to this link: Open Source Machine. There is also a Yahoo group (link on the Open Source Machine site) with files and lots of interesting things. They are focused on lathes, mills and drills, but there are lots of goodies here.

I made a cutter for round stock out of two pieces of leaf spring. I have them mounted so they swing past each other. I drilled holes the sizes of the stock I want to cut through both plates. Just insert the stock and pull on the handle to shear small rounds.
The blades are about 3"x 4" rectangles with a pivot hole in one corner The pivot is a 1/2" grade 5 bolt. There is a piece of angle iron welded to one blade so that it can be held upright in the vice and a handle welded to the other (moving) blade. Simple as can be and I can cut 1/4" hot rolled steel with it. Drill the shearing holes as close to the pivot as possible for maximum leverage. -
For those having problems, go to this page first:

This is a picture of the forge that Rob Gunter and sons used at the 2009 SaltFork Conference last october. http://picasaweb.google.com/Roy.L.Tate/SaltforkConference2009#5395250849539729714
Check the Saltfork web site for our 2010 conference! http://www.saltforkcraftsmen.org/). Click next to see more photos of the forge, or "view all" to view more coverage of the conference.

H. Is that the Sandia recuperative style forge. ...
Got any pictures/ info? -
Arftist, I'm basing it on the previous owner's advise. The flywheel says 250 RPM, so I'll find out soon. You guys might not believe it, but I don't have any electricity in my shop yet, so I haven't been able to play with it.
I'm trying to be patient. :mad: -
Welcome to IForgeIron, and I hope to see you at a Saltfork meeting! I usually go to the "North East" meetings, but we will have other meetings closer to you.
Check Saltfork Craftsmen for meetings. You should call if you want to go to a November meeting, as there may be some changes. -
I'll post some photos here when the gallery is fixed, but for now, here is an album from Picassa ... Picasa Album - Roy Tate - Kerrihard Power Hammer.
Someone at the 2009 Saltfork Conference suggested that the welds would break soon enough if I just used the hammer hard enough. I will be sure to inspect and lubricate the hammer before each working session.
Thanks for everyone's input on the Kerrihard. I'll try to post some useful information in this thread as I learn. -
I just bought a working Kerrihard mechanical hammer. It looks like an older 30 lb model. It needs a slightly smaller pulley on the motor shaft, and perhaps a few older bolts replaced. The guy painted it red before tail-gating it, and the upper die is welded in. It has an expanded metal safety cage for the spring mechanism.
Has anyone found any resources on the web for this model? Someone at the 2009 Saltfork Conference recommended that I ask Sid Suedmeier. I figured I would ask here, and educate myself some.
Does anyone have any pictures that you could post on IForgeIron? I guess I'm most interested in a picture of the upper and lower dies, and particularly some measurements of original die sizes. I tried searching the Galleries to no avail.
I will add a few photos to my gallery and add a comment with links soon. -
I will second Glenn's cautionary tale. I had an S hook ripped out of my hand and it hit my finger as it went by, breaking a small blood vessel, but thankfully nothing else. It hurt, and scared me. I thought I was treating the wire wheel with great respect, too.
I was wearing gloves, an apron, a long sleeved close-fitting shirt, and a full face shield. I was also standing slightly to the side - out of the direct "throwing path" of the wire wheel.
I've thought recently that I will avoid putting a wire wheel on a full speed bench grinder. Perhaps the "router speed control" will help.
As several have already said, it is very important that you think about the dangers to yourself and others as you work. Don't be afraid to stop working and think about better / safer ways to do something, or wait until a child has left the area. -

I enjoyed the conference again this year. It was difficult to decide whether to watch Bob or Alison. I watched a little of each of them.
I picked up a Guillotine "Smithing Magician" tool based on the Winter 2000 "Hammer's Blow".
I promised someone at the conference that I would post photos of Bob Alexander's Iris. I only have photos from Sunday.

I looked this up in Google, and found a handy PDF discussing problems that can occur with this type of burner. Yes, the guy sells burners, but he has a very detailed installation, safety systems and a troubleshooting section as well.

Notice that several reply so far mentions raking out coals and dropping them in water, and not dumping cold water on your hot fire pot. This would crack the pot sooner or later.

I hope this helps those who are experienced with tool steel and will be giving advise. -
Here's some pics of the first burning of coal in the new forge. I'm a little worried that i made my fire pot a little too deep. When working on long pieces i'll have to build up a pretty big pile of coal to get the sweet spot of the fire up to the top of the firepot. I'm still pretty in-experienced with that. I think i may have to modify my firepot, cut a couple inches off around the top making it less deep, which will also make it smaller in size unfortunately. ...
Would it be possible to clay the pot instead of chopping it up? At least then you could experiment with different depths. I do not have a formula, but I understand that the cheapest unscented cat litter is plain clay, and one recipe suggested clay, ashes and maybe more ingredients as a crude fire clay. I'm sure some of the more experienced smiths will have an opinion on this. -
I would find a local club (again ... look on the ABANA web site for clubs in your state) and attend their next meeting. When you get there, introduce yourself to the host, and let them know that you are new to the craft. In our club, Jim Carothers or another senior member will usually take some time after the demonstrations to work through a beginner demo with you. That's how I made my first "J hook".

Made of copper with wood handle,Hint blue pen and keyboard isnt the answer.
It might be a capping knife for cutting the wax cappings (top layer) off of honey bee combs. It looks like some that I have seen. -
That looks like a Saltfork Swage Block (SCABA). It should have a few letters on it ... If not, I think one of the other blacksmith clubs made a block from the same pattern.

Zinc plating (galvanizing) ... A white vinegar bath will remove it in a few hours to over night and there are no toxic / hazmat consequences.
... Perhaps if I'd subbed to the list and posted the plans a couple months ago you might've given a "T" jet a shot, maybe not. No matter.

It's good to know that white vinegar and a little time can substitute for muriatic acid. I have heard that you should provide plenty of ventilation during this process.
And ... you were not too late to share the T-Jet burner with me! I have a 358 gallon propane tank, a freon tank shell, and some 1 inch pipe. This burner is so simple that I might as well try it out. I can always buy a T-Rex shorty or a modified side-arm later, if I am dissatisfied with this burner's performance.
This burner design would be great as a blueprint. -
Am I dumb? I dont see any pictures:confused:
I usually look under the member galleries for new photos when I can not find them ...

My dad used to drive a propane truck, going to houses and filling their tanks. I told him once that I could use a propane tank, and he mentioned a 275 gallon tank on a trailer. That seemed a bit large to me, but then he remembered a smaller tank that came off of a tractor or a truck. It is a 43 gallon (358 pound) tank, with valves for liquid, vapor, bleed off, vapor return, etc. And of course, a pop-off valve just in case someone fills it too full. This tank is heavy! I could lift one end, but we used a tractor's front end loader to load it into my truck.
I still need to get the gaskets inspected, get a cap for one of the return lines, paint it, and get it filled. So, expect to see some questions about propane forges and burners soon. (I know there are several blueprints, and a million articles on the internet.)

I'm only able to work in my little shop at most once a week, and my day job is desk work. I usually work for 2 to 4 hours before I start feeling unsteady in my aim. This depends on whether I use the 1.8, 2 or 4 pound hammer most. I am sort-of ambidextrous, so I switch hands every 30 minutes or so, but I still wear out. Whenever I start feeling the "wobbles", I straighten out the piece I'm working on and throw it on the dirt floor, or switch to the light hammer and carefully finish up.
Recently, I had the chance to work as a striker with a more experienced smith, and the 16 pound sledge tired me out quickly! I would beat for a few minutes, and I was happy when the metal needed more heat. :) -
I did this very thing today! A friend and I just straightened 2 chunks of 3/4 inch car spring (possibly 4140) by heating in a large gas forge, and unrolling it using heavy tongs to hold it in position, a pair of bending forks on a 4x4 inch post, and a piece of 1 inch or larger square tubing. The tubing acted as the lever to straighten, the tongs braced and helped pull. We did final straightening on the anvil, using the step area to work more extreme kinks out, and the top plate for final tweaking.
We straightened two springs, and it seemed easier to heat 2 or 3 loops of the spring, straighten and let it cool, then straighten another section. When we tried heating the whole spring at once, it came uncoiled in a big mess, and was harder to handle. -
I ... was thinking to cut it in sections first with a hack saw or similar.
Take it from me, don't try to hack saw a 3/4 inch car or truck coil spring unless you want to use one blade per cut. Even a small coal forge with a decent blower will get a section of the spring hot enough to cut with a hardie or a chisel (using the chisel took 3 or 4 heats for me). -

Thanks for posting the picture. I have his book, and I have been reading it, but I really need to take some time and light a fire.
