My screws have metal inserts like your plastic ones.
I have two nuts locked against each other for anti backlash, each nut has I
think 5 single turn races.
I left the metal inserts in, inserted the screw into the nut just at the
bottom and loaded the ball track by track while gradually winding the screw
in.

Aaah hah,
Just noticed something else about the plastic inserts - they're
definetely not "squirted in there", they seem to be little cross-over
bits which cause the balls to be recirculated back!
I'm guessing the only way to repack this is going to be to fill the nut
with grease, carefully load in the balls, then wind it on.. and hope.
Looks like it's going to be one of those REALLY tough ones...
Regards,
Abby

How well does your CNC retrofitted desktop mill performs?
