so after being on this site for awhile and looking through posts and posting a decent amount myself and talking about building a low budget brake drum coal/charcol forge here is what i have so far, i got the drum from the scrap bin at the auto parts store before they canned me, the pipe i found spelunking in my dads old and very very tired garage, its 2.5 inch diameter pipe which is perfect because that was the size of the hub hole on the drum, the plate welded to the drum is 1/4 steel, i stick welded the wheel stud holes to the backing plate and then stick welded the pipe to the plate, which was probably the hardest part so far( i miss the tig welder i used when i was taking classes) reading through the threads i ran across several that were discussing wooden forges so that is what i decided to make since i have plenty of lumber laying around, i cut four pieces of 2x5.5" and sanded them down then stained what i intend to be the outside and beings as i am in washington and it isnt exactly optimal staining conditions the wood is sitting in the garage to cure then i will assemble it. now comes to my questions, would it be a good idea to stain the entire thing then coat it in polyurethane to protect it against the weather or would that be a rather large fire hazard? im going to fill the main box of the forge with sand so i will get good spacing from the wood that way, as far as a blower i havent decided yet what i will use. Ideas and criticisim are both welcomed gratefully, oh and i almost forgot, would it be a good idea to line the forge with refractory cement to shrink the area the charcol is going to sit in? i was thinking of an upside down funnel style. thank you everyone for your time.
