Bended ballscrews. What i can do?

[Wal]

I am asking because if i put the node in the lower spot of the thread, as i turn the ball screw and have the indicator stable, the node of the indicator will pass from the lower spot to the higher spot of the thread( as the screw turns). I don’t know if i make my self clear.
Is ti logical to put the indicator node on the ballnut that has a cylindrical outer surface so i can capture the TIR.

Would you not use a flat tip probe - like the one 2nd from the right in the pic..?

Yep them's what's needed Wal but like finding Hen's Teeth unless your prepared to splashout on expensive dial gauges and then they are expensive for a one off job.!

Edit: I retract that statement I've just found this set at Arc eurotrade (bottom of page).!!. . . http://www.arceurotrade.co.uk/Catalo...nt/Dial-Gauges
