Re: Bridgeport retrofit servo questions

Thanks Les. Not sure yet if I am going with the Geckos or Rutex servo
drives yet...If I stick to the original plan of 75v, then I should be
good either way. If run 1:1, then it's best if run only to 75v anyway
by your speed calculations.

I noticed that the belts on the BP are pretty wide...what does the
HTD style offer? Is it trapezoidal or round toothed?
