Well I bought a new drum the other day,($72 dollars and some change. ouch
) and made a few changes on her. here's a few pics. the air regulation on this new one is way better than my last one.the last one I did had a 1 1/4" air intake running up the side of the drum. this one I installed a 1/2" ball valve. and used a 2" pipe for the exhust.
smoked a 5lb round eye roast, it came out dry but thats a diffrent thread, for some other time.
