Hi folks, Dave here.....aka Tigman from the chopper forums.. I am a self employed fabricator who has just recently bought an old Buffalo forge with electric blower. This well used forge needs some work but I want to bring it back to life. My buddy found it in Sandwich, MA. at an old blacksmith shop that seemed to die off. So I have some questions about set up. My welding shop is 36 x 24. I planned on fabricating a new hood and piping it thru my barn wall using a type B style vent tube. (if that makes any sense) Like my mr heater uses that hangs from my ceiling. I don't want to burn the place down so any suggestions would be great. I have read a couple of posts and am seeing Q's like "did you clay the box?" Not sure what this means.. Is this simply extra protection for the thin wall sheet metal walls of the forge? And where do I get it? Also the coal dump I think it's called in my forge is cracked and I'll have to pull it apart and see if I can weld it, looks like it might leak air and mess with me.. anyway, hope to hear back from some of you folks for some guidance.... thanks in advance..... Dave
