Spindle ballscrew bearings and encoder mount

Late July 2012

Since almost every other bearing was in lousy shape I decided to pull the ballscrew bearings out of the head and replace them, and did some cleaning up while I was in there too.

Pulled ballscrew out, decided to turn top end for a HEDS style encoder since 1/8" is a common (read: cheaper and more available) size for encoders. Shown here: a blurry photo of me indicating the screw to make sure I'm centered up on the lathe:

Shaft turned down:

Success! Encoder fits snugly!
