Two Piece Truss Tubes

I'm doing an 8" "travel scope" and thought it might be good to have the poles telescope or separate into 2 pieces. After pricing monopods for telescoping poles, I decided to try 2 piece tubes using some cutoffs I had laying around from a previous scope project. The picture should tell the story for the most part. The side with the bolt has 2 tube inserts and a washer that all help to keep the bolt fairly straight in the tube. The larger fender washer is used in between the tubes when assembling to give the tube ends something to rest flat against. My total lengths are only going to be about 30" so I think this will work. Assembled and tightened, the 4' test poles (2' on either side of the joint) are pretty solid. At 30", there should be very little flex. I hope. Anyone else using something like this?

Bill, I have not used the design you mention for joining poles, but I think it is a nice design. Maybe adding epoxy to the nut/inserts might help to make sure they don't come apart, although tightening them down may be sufficient.
