Re: [CAD_CAM_EDM_DRO] My CNC Project

Bill,
In the Vexta Motors, there are two ball bearings preloaded with a wave washer
spring. I added additional flat washers to tighten up this and take the leadscrew
thrust. So now, the handwheel end-thrust control is not needed.
I will do some serious metal removal to test this and the coupling out soon.
I agree, Sherline could do better on the leadscrew end mounting (bearings?).
