[CAD_CAM_EDM_DRO] Binding Table - How do I regrind/Lap the ways ? ?

Hi All

I have a Old Bridge Port that was used for
cutting silicon mirrors and table has been
worn in the center. They only moved the table
about 10" in the X axis for it life.

I have removed all the silicon build up on the
ways and knee.

My homebuilt CNC system can only operate on 12"
of X travel before it binds. It's a 12"X44" Table.

When I tighten the gibs the table binds at the
ends. Is there a good way to manually LAP the
table ways ??

Thanks
Mark
