I spent the last month working in my spare time to complete a midsized smokehouse. I'ts made from plywood, 2x4's and other assorted materials. I got the idea to use floor vents to vent it after seeing them in another build on this site(thanks) I tried to power it with a 1500 watt 2 burner hot plate and had a terrable time trying to get the temps I wanted. The body of the burner had speacial tamper resistant screws so I could not bypass the temp controls and using a 12/3 extension did not help so I scrapped that idea and decided to go propane.The only 10/3 cords I could find were 50 or 100', way to much length and cost to justify. I purchased a cast iron camp stove that produces 15,000 btu's from Cabelas, attached a 11" w.c. hose and filled the bulk tank for my gas grill. I test ran it yesterday and got heat up to 230* in five minutes Today I set it up to do a rack of ribs for another test run and it was 10* here. With a drip pan in place and the rack set on the top I kept it at 200* for 2 hours while they smoked. I removed the drip pan and foiled them for 2 more hours and ran the temps at an almost constant 250* It ran a bit high at first but the vents gave me pretty good control of the heat. The last hour they whent in without the foil above the drip pan to finish. The ribs turned out almost as good as they do when I make them on my pit so for a first try on a homemade cabinet smoker I was pretty pround of myself. I plan to use this set up more for jerkey, summer & smoked sausages so the higher heats are not neccesary. 140-180 is all I need for that stuff, On occasion I get asked to do a couple of butts or multiple racks of ribs for get togethers and it would be nice to have a bigger rig to work with, now I have it Here are some pics of the smoker, I have some of the build in proccess but need to find them. All said and done I am quite pleased but do have a few modifications to make, first and foremost will be to add cementboard to the bottom 24" (another idea taken from a fellow member) Second I will look to place the drip pan a bit higher from the heat source. and I may re do the door and make it more like that of a kitchen cabinet door. There are other thing to tweek a bit but I will wait till summer for that since that is the time it will be used most, may as well wait for those condition before making to many mods. Anyway sorry to get to long winded about it hope you enjoy the pics and approve of the build, later all -M.M.
