Duk, I watched several videos before choosing the design. I liked the T design because it is simpler than passing the tube thru the container where you have to find a way to prevent chips/shavings from entering the smoke tube - not so in the T design.
Basically any container will do. I was going to use a coffee can until I spotted the liqueur tin at a friend`s shop. It cost me a couple of bags of sandwich ham. The black pipe fittings are 3/4" - 5 to 6" for the outlet and 3 to 4" for the inlet, 2" for entry to the tin, plus a T. I used electric box lock nuts which, to my surprise, have pipe threads to connect the short nipple to the box lid.
I had some 1/4" brake line that I used for the air supply. It begins with a 1/4" brass barbed connector with the barbs ground off and epoxied in place. The plastic line connects the aquarium pump to the air intake. I centered the brake line in the 3/4" nipple with a drilled out wood dowel about 3" long. The brake line was epoxied into the dowel which was epoxied into the nipple. The air tube ends about an inch past the T and creates the venturi.
The 3 pipe fittings and plastic air supply line are all loose fit for ease of disassembly and cleaning.
I drilled 3 (only needed 2) 3/8" holes about 1/2" above the tin bottom. I made a sheet metal baffle that angles towards the air inlet holes so the shavings are falling toward the burning shavings.
I have a lot of cherry that I use for the shavings. I haven`t found an easy way to make chips out of it although I`m thinking about cutting it into thin strips, ganging them up and cutting them into chunks on the chop saw.
I still have to put it thru burn tests to see how long the burn will last and also to try adding some chips to the shavings.
Long story for a fairly simple project.
