There are those on the forum who can probably explain the particulars. I would say the air supply is part of it, size of the fire bowl, and somehow the angle of air delivery. Sorry I can't be more descriptive.

I have been using a bottom blast fire pot that I inherited for seven or eight months. I am using charcoal and looking at the jabod types. When I saw the Mark III I knew that was it. Four hours at the forge and and only one coal bucket of charcoal, where I had been going through a bucket an hour. Thanks Charles and everyone else for posting pictures and ideas.

Thomas Powers, thanks for the nudge about the stand. I knew it was too short. It's a lot more rigid now.

Thomas, when I find the right anvil height for me I will build vertical or find a good stump. Charcold, you are correct. It weighs in at 155#.

Pretty sure they are casting defects. They aren't uniform enough to be drilled and different depths. I drilled and tapped a couple of the bigger ones and screwed a bolt in, cut it off and smoothed as best I could. I decided that was more work than it was worth. My main curiosity is about the way it is marked. Hadn't seen that on any of the images. Always the arm and hammer proud, sometimes II&BCo as well.

Anybody familiar with this marking? No arm and hammer, no II&BCo. I picked it up at auction a couple of years ago for $100. I just find an edge or surface to work on. Sad how abused it was.

Sorry for the confusion. I probably should have started a new discussion. I appreciate the responses and info.

No sir, I am not trying to be hard headed. This is what I found on the Hudson tool steel sight, S7 Shock-Resisting Tool Steel is an air or oil hardening tool steel that is characterized by very high impact toughness. That is why I asked. If it's not suitable I will move on. Thanks

I misunderstood, it is S7. 16"x7"x7" or 16"x8"x8". I am trying to get more information, price and hardness.

There isn't much high tech around here so if it's not annealed I will leave it be. Thanks for the responses.

I have an opportunity to pick up some chunks of A7 tool steel drops. I have looked on line and can't find the information on how brittle it is. So my question is how would this steel work as an improvised anvil? I know this is the place to ask. Thanks

I like that better. Cheaper and more controlled. Thanks

My shop is not heated, so my question is, has anyone used a magnetic block heater on their anvil?

I got it up and running. It is small but easily enlarged as needed. I have an unlimited supply of Osage orange, mulberry, honey locust, etc so I am using charcoal. The bar oil did the trick and quieter.

I hadn't thought of bar oil, that I have. Thanks

I am in South Central Kansas. Yes, a Buffalo 200 blower came with it. The blower is functional but won't hold oil.

Another picture.

I am new to the board even though I have been reading for awhile. I have an old Buffalo Forge fire pot that I have been unable to find an image of online. Most that I see the fire pot and tuyere are bolted together. Mine is two halves vertically with clinker breaker and ash drop. I don't know if this was a bad design and was discontinued. The photo I have isn't very good but it is all I have for now. It was my Grandfather's and probably hasn't been fired in 60 or 70 years. Any information would be much appreciated. Laynne
