    Oh - and notice the bungi cord on the half nut lever. After a few direction changes - The half nut opens up.

    Yes - I am looking for a 12 ft ball screw - but the price has to be right...

    That makes perfect sense, except there is no hard shoulder opposite the threads to preload the bearings unless one bearing is up against the ball threads.

I made a bearing block that has a section that keeps angular contact bearings apart. The nut pre-loads the bearings. (going to use jam nuts.) the opposite end - we just have a bearing to keep it from flopping around..
