The hose clamp is what I should have used since I didn't have fittings for the ends. I got lucky and was a winner in the A-Maze-N products contest and got the 12" tube smoker, so I haven't been using my homemade cold smokers since. There was a great deal on Traeger 20lb. bags for $14, so I bought a bag of pecan. I called Traeger because I wanted to know what percentage of the flavor on the bag was in each pellet. They are just like BBQ'ers Delight 2/3rds white Oak or Alder for heat and 1/3 is the wood on the bag (fuel and flavor.) The 1lb. bags of BBQ'ers Delight is 100% the flavor on the bag. I have several of these in pecan so I'm filling my tube smoker 1/3rd. BBQ'ers Delight and 1/3rd. with the Traeger pellets for more pecan flavor. Then just shake it up to mix. The Traeger pellets are good by itself. I just have to keep a closer eye on the temp. when cold smoking cheese.Here's what I cobbled together. I had a piece of 1/8" mesh SS screen. The ends are 1 1/2" copper. One end is a cap and the other just pipe and I beveled down the end a little. I have since removed the hose clamp as it wasn't necessary. I get 4 hours and a bit with Traeger pellets.
