After a lot of looking threw the smf forum i decided to try build my own. I didn't need a real big smoker and i got lucky and came across a 80 gal air compressor tank that was out of service. My plan is to make it a RF type smoker on a small trailer.I found a trailer but i think it will be way to wimpy,i plan on two inches of insulation around the fire box as it can get kinda cold up here in the winter ,that when i will have the most time to do some smoking.I have read a lot about gas in the firebox and under the plate what are your thoughts on this ? Here are some pics. Drawing for my door Door hinges made out of 3/16 Door is 1/4 the cir of the tank,decided to go off dead top center ? not sure if that's right ,but it's done. The first few cuts i was vary nervous, I did not want to make any mistakes !!!
