hello membership. new to the forum. and have some question. as most newbies do. just recently, i was laid off. and got bored. so i was surfing on you tube. and stumbled upon home made smokers! being the tattooed trailer trash i am. i found the whole concept of smoking meat, shall we say intriguing! granted , i have heard of the concept. just never outta a old fridge or propane tank let alone filing cabinet! yes, i have come across the drum grill even saw a trash can grill. enough with the small talk. so here are my Q's 1) i'm wondering what is the best source of delivering heat? wood,electric or gas and of course charcoal? 2) being this will be my first smoker. does the membership think a 4 draw file cabinet, would be a good candidate for a starter smoker. i have access to one. and the varies parts need to customize to my liken an needs. thanks for any input or help.
