Haha, yeah, thought I'd include that in the vid in case anyone (including myself) starts thinking I am in any way proficient at this stuff... Three escaped, but only one made it to the floor. the others got held up on the extended paper towel trap. I am reasonably certain they all found their way back in - there wasn't any space for more bbs in the nut anyway...

Ok question on the new ball screw though - Started a new thread about it:
