I've read this thread about building a mini reverse flow smoker out of expired steel fireman's air tanks http://www.smokingmeatforums.com/t/64702/building-a-reverse-flow-miniature
I need to build one of these but had little luck finding any of the steel air tanks. Shopping at Harbor Freight one day, my eyes spotted a suitable tank, a five gallon portable air tank, item #65594 for about $25.
Picked up some 8" flat bar and 8x8x3/16" square tube from my local steel yard today and started laying out my cut marks on the tank.
Before cutting her up
Cut off handle, bung will be rotated to be the grease drain
One of the two legs cut off, used a cut off wheel in my 4" angle grinder.
Little polishing of the old welds
1/2" water valve (just what I had on hand) for grease drain
Laying out center lines so I can make square cuts. A 3" chunk of Channel iron works great to draw lines on a round drum
Measurements, top of firebox will be about 2-1/2" below center
Little gift to myself last month, found this neat metal cutting band saw off Craigslist for $175. Going to try and get it to cut that massive 8x8 tube!
This is my first reverse flow build, if you guys see something I'm doing wrong or see a problem, please let me know, I hate cutting and having to re-weld stuff back together.
Keep tuned, more to come!!
