The outer pipe sections could be screwed to the inner one. The inner pipe would be supported at the ends by caps with bearing holes bored in the center, and a sprocket would be screwed to one end of the pipe.

Squirrel - check out pvc pipe. There is a schedule 80 pipe who's id is the same as the od on a schedule 40. You can cut small pieces of the 80, then force them over the 40 to act as guides. I believe is was 3" or around there for the schedule 40. In this way, you don't have to even use fasteners or glue. Just the friction holds it very well.
