Ball Screw Removal

[smarbaga]

hello:
I have 3 ball screws on shafts ( of different Diamaters ), with ball nuts.
I would like to cut the shafts to lengths and turn the ends to accept bearings.
? . how do i remove the nuts ( and replace them ) without disturbing the bearings.
* or should i leave the nuts on the shafts and try to secure them while i spin the shafts in a lathe at thousands of rpm's.

thank you .. in advance for your help .

When I got my "NOOK" brand ball nut, it came with a small cardboard tube with an OD a little under the leadscrew's small diameter. It was kept in place with a plastic tie-band. All I had to do was slide the shaft inside the cardboard tube then start turning the leadscrew! The same worked in reverse when I needed to modify the leadscrew!

Find a piece of pipe, or tubing that has a good outer diameter !

so i would but a round peice of pipe, plastic or anything close to the small screw dia. up against the end of the of the shaft and unscrew the nut onto this round peice , then maybe black tape the nut onto it untill ready to re-insert .

thanks for that tip.
i will start with a clean junk free work area, perhaps with an old sheet down incase i go crazy and my balls fall out
