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.

This is what we did here. PVC center, larger diameter PVC outer. Caps in the ends with bearings inserted.
