It's pretty much inevitable that there will be a big gap in the speeds
at the point where you switch from motor-belt-above-spindle-belt to
motor-belt-below-spindle-belt on the pulleys. On my 16-speed H-F
Chinese special it's from 870 RPM to 1440 RPM. All my machines have
180VDC motors with KB Electronics speed controls, so that gap isn't a
concern for me.
