Bridgeport ballscrew backlash

I have a Bridgeport (was a Boss 5) that y'all helped me rebuild with
gecko drivers last fall. Thanks for all your help, its running
great even making a little money. I has about .002 backlash in the
ballscrews, both X and Y, and I was wondering if anybody know a good
place to have them rebuilt, or to buy replacements. It's not a
major issue, since my software (DeskCNC, which is a great program by
the way) compensates for it. But I have broken a few cutters when
the direction changes suddenly in a program. I've been told there
could be a way to adjust them, but nobody I know seems to know how.

Thanks in advance
Nate
