Re: [CAD_CAM_EDM_DRO] oversized bearing balls for ball nuts

Joel,

I still think at best you would need balls .002 inch oversize as the balls are on "both sides" of the screw. Hence my thinking that .147 would not even fit.....

size and backlash and he says it's "approximately 1 to 1 with this screw".
I have enough room for two nuts on my x axis but there just isn't room on
the y axis. The one nut I have is less that 1 thou backlash, I may just use
that on the y and get another nut and put two on the x. (If I can't get the
oversized balls)
