How to align ball screw to linear rail?

[phill05]

So I can get accurate results. That method is like balancing a ball on top of another ball....



I watched the video, thanks. It shows the person indicating somewhere around the top of the ball screw and then carefully pivoting the mag base and metal plat up so he can move the Indicator up the other end of the ball screw.............I can't imagine that being good engineering practice.

But if thats the way its done, I guess I don't have other choice.
I just thought there might be a better way.

Most screws have a different finish in the vid it shows a ground flat to crests to work from most don't so if you wind the ball nut / housing to one end take a reading then wind to other end take a reading and adjust if needed,
