I'd be worried about the thermite melting the cast iron off the bottom of that Fisher's face plate myself.
Yeah, I'll have to keep the pre heat to a minimum so it sucks the heat out of the weld faster. -
The steel face is awful thin. Down to about 1/8 inch. A cracked edge on 1 corner.
It's a block anvil. Lots of rebound and no ring. Typical Fisher. I hope to keep it's personality.
EDIT: Can't find a pic of the old girl. Here is a place to go, to see some of my more, refined thermite escapades.... YouTube - steelace1p1's Channel -
you should Post pics of it here so we could see how bad it is. It cant be that bad. Remember youl need to harden the whole surface afterwards because your plate will probably be normalized and way softer than the original face. Your undertaking is out of reach for alot of people i hope you get all the information you need before even thinking about it.
Those are good points!
I chose 4340 because even in it's annealed state, it's quite stiff. Heck, even at forging temps, it's quite stiff.
As for the information, I'm going on something like my 275th pound of thermite over the years. Lots of trial and almost as much error.;) An occasional success, here, and there. I do , finally, have the refractory down though. Took awhile.... -
Bennett, I hope you dont destroy the anvil! It would be a shame:(
Good luck
Thanks.
Yeah, me too. That's my favorite anvil. Going to use 4340 sheet. 1" thick.
I got the refractory down to use for the form. Should take about an 8 pound charge, to produce a 4 pound weld. I can always do 2 runs, if there isn't enough. -
I'm going to try it.
It might take 2 runs. You just need to make a form, put the anvil on it's side and pre heat the joint/face with a big rose bud. That's all.
I have a favorite Fisher that needs a new face. I'll post it if y'all want. ... when I get around to it. -

Now if you want to experiment with your own alloying look into thermite experiments done by a fellow and posted over at the bladesmith's cafe at swordforum.com. Of course you have little control on uptake in such experiments. And thermite does not play nice, any mistakes and you will be on the evening news and the FBI's "list".
That's true. I heard someone say once; "You need the right combination brains and brass when messing with large thermite charges. Too much of one and not the other, will inevitably get you in some form of trouble".
Welcome, BTW. Don't be afraid to ask the bold questions and try new stuff. -
but ya gotta know that Jerry is a member of the >5000F club
Hi ya Steve.I also read from a "Fundamentals of Metallurgy" text, something about molten Iron acting much like a solvent in dissolving other higher-melting-point-temperature elements.
Yep. You still need a lot of heat for alloying tungsten though. That's were ferro alloying chems come in handy. -
Cool links, as usual Czar:)
You don't need to reach the melting point of refractory alloys.. BUT you should try to get close. I did it, but used ferro tungsten. a little easier than using elemental tungsten. here is how I did it. YouTube - Boiling Iron -
Can do!
Grandpa was a SeaBee, (plank holder), and was stationed at Pearl when it happened. His unit was the first on the scene, and began work, even as the attack was going on. -
St paul.. I just drove thru there a couple hours ago lol.
Wow.
It's not Rodeo season, so you must have been lost. -
Well, nice to see you here. I post on Don's site as R.K. Nichols. We have conversed on Don's site.
Nice.
I like this site, although I mostly lurk here.
Lots of good stuff in the archives. The alchemy and formulas, is right up my alley, so to speak.
A little off topic, but someone said you can't throw a dirt clod in Oregon without hitting a smith.
We need a giant hammer-in here. I'd volunteer, but I only have an acre. -
J. Bennett, do you post on the Don Fogg site as "Bennett"?
Yep.
that's me. -
Rural St. Paul, closer to old Champooeg, on the east bank of the Willamette.

Howdy, and welcome.
Looks like the south is well represented here. -
Grants Pass eh?
Got any good Sasquatch stories?
Howdy from Champooeg. -
Machining is a great profession that includes a lot of self satisfaction as one of its rewards. Anything and everything (not made by God) has machinist(s) fingerprints all over it.
On the downside (and not trying to change your professional dreams), prepare yourself mentally and financially for possible employer layoffs, down sizings, plant closures, labor strikes, etc. These have been a way-of-life for me many times since the early 1970's. It seems like no employer, product line, job location, etc. is immune to any of these then or now.
In 1984 I opened my own machining job shop for a more stable form of job security. Little did I know then that personal health issues would eventually plague that income source too.
Yeah, buddy.
Try and not limit your skills to just CNC. You may like programming better, so study machining language. Know how to do complicated set ups, by hand. You may like tool design/fabrication better.
My experiences, is that the term "cnc operator", tends to be mass production, the same part, day after day.
I have a machinist degree, but I took extra classes to upgrade to engineering. Opened a lot more doors. Worked as an engineering aid, (fancy draftsman), when the economy was laying off machinists. Gave me more options. Good luck, Jerry -
I've been experimenting with homemade carburizing compound. So far, I've had a little success.
If you are just packing it, leave out the sugar.. Differentially carburizing. - Bladesmith's Forum Board -
The same store that sells Bon Ami sells 20 Mule Team Borax which is excellent flux.
Yep.
I was just wondering if the feldspar and calcium carbonate would be good together in the reduction of iron ore. Feldspar can be very aggressive, (a good thing at times). The idea as a welding flux was just extra. -
Bon Ami, the cleanser found in many kitchens. It sounds like it could be a flux/reducing agent for smelting, melting and maybe welding.
The ingredients are simple. sodium carbonate, calcium carbonate and feldspar, with a bit of organic detergent.
I was wondering if you could heat it up to burn off the soap, and use it as described??
Thoughts? -
I'm making crucibles. Don't ask. I'll let you know if it works. Thanks

Can't answer your question, but thanks for that link! Jerry

@Jerry: I don't live far from Newberg/Dundee (25 minutes). I'd be cool to see his operation. It's probably modern, but it would be useful nonetheless I'm sure.
@Niel: Robert was telling me about that. Its a bit of a long haul but it sounds interesting. We'll have to see.
I know he had guys flown Over from France. So not sure how modern. Probably 50/50 I would guess. -
There is Blade west in Portland, in September. Nice little show.
If you are studying cooperege, do you live near Newberg/Dundee? I have a friend and neighbor, who owns a winery, and I think he has a cooperege, but not sure. Got a nice flat bed of oak stave scraps a while back. Makes nice charcoal. -
Cooper,
I also live about 15 miles from Brooks.
I might make it there Sunday. Jerry
Colored nitriding at home?
in Finishes for Metal
Posted
Hello.
I'm looking for a home, surface nitriding technique, if that is possible. It's more for a durable surface coloring system, than a hardening scenario.
I know they do that for high end plumbing fixtures and such, but in a million dollar vapor deposit chamber.
Any cool ideas out there? Thanks.
