Hey guys thanks for the generous responses. This is gunna be my first time using a forge and doing any kind of smithing, I mainly plan on using it for blades, forming and quenching. I would like to do some forge welding with it. I am leaning towards putting in a firepot made out of 1/4 mild steel plate and insulating the space between that and the tire rim. As for the floor of the forge I'm thinking of taking a 2" pipe endcap and drilling some 1/4" holes in it. The ash dump will just be a end cap screwed on the bottom. My air will either be coming from a 6hp shop vac or an inflated unit for a greenhouse, I'll take a look at the specs tonight to see if its sufficient. I can make a quick drawing tonight and I'll post it so you guys can take a final look and make some suggestions if need be. Thanks again, Johan
