Re: [CAD_CAM_EDM_DRO] Re: Grizzly CNC update

Hello Paul

Before you refit the bearing housings, make sure that the bottom of the bolt
holes which register with the bolthead have been machined out flat,
mine had been just drilled, which forced the housing to a set possition when
the bolts were nipped up,due to the angled seat, machining out flat will
allow them to be set to thier best possition when the ballnut is nearest to
the housing , and then they can be pinned.

Regards

Peter Smith
