Hello. I have a bit of backlash on my ballscrew (0.002")and I'm thinking of just reballing it. I know I should have it regrind too but I cant afford it right now. I was thinking reballing with bigger balls. I measured my current balls and they were 0.001" smaller then 1/8" witch is I think the original value. If I change them with original value I will get rid of half of backlash, but how much bigger balls do you think I can put in without the risk of jamming? There is a little groove in the bottom of the screw thread and but else then that, the screw should only have wear to the sides and if you think about the geometry then the bigger radius ball can easily jam. Thats why I'm thinking just a little bit bigger ball and maybe when it runs for while I can reball again for bit bigger again. What you think?
