Guys... If for some reason you wanted to cut a 2" seamless tube axle in two and allow both halfs to rotate using a center joint, what would be a good joint to use? I'm talking only about 1 inch +/- of total rotation from one extreme to the other. I'm more interested in something from a donor than something custom built at a machine shop etc. It would have to be strong and durable...and not ugly. The joint would have to be of tight enough tolerance to prevent sagging or looseness that could result in noise and chatter. BTW...to be clear...I'm NOT talking about setting up an axle as a swing axle. Thats easy, but not what I want. I'm talking rotation like you find in a steering column for lack of a better description.
