I found myself needing a smoker and, being
frugal, I decided to make one.
I used an empty disposable propane tank for the outer body. I wrenched off the threads and it created a hole that was perfect for a piece of 1/2" copper. I secured that with a conduit nut from the inside.
Making the bellows had me perplexed until I came up with the idea of cutting all the pages out of a small hardcover book and using the hard covers and the binding as a hinge. Of course, no project is complete without duct tape.
I put some trim stock inside to make it spring back after being compressed. For the airway, I used a piece of brass cut from a spent rifle cartridge.
Inside the propane canister is a soup can with a bunch of holes in it. The propane canister has a false bottom in it so that REALLY helps with the heat.
I just used some leather to act as a hinge for the top of the smoker. That's the only drawback, I wish it had a tighter seal. It doesn't hurt anything the way it is (it just adds a little smoke for the flyers!) I think that I can make a slit in the outer main portion of the propane canister and taper it in a little. That would make the top fit right over the main body.
I hope you like it - or at least find it interesting! :)
