Re: [CAD_CAM_EDM_DRO] My CNC Project

hey rich
neat idea for the motors and thurst bearing but I am not quite sure what you
did. I too have a "wave" washer that you talk about in my motors that keeps
the armature of the motor up against one of the bearings (the rear one).
What did you exactly do? I also agree it would of been nice to have some
support at the other end of the leadscrews on the sherline machine..but who
knows maybe then they would have to be perfectly straight? thanks
