The beauty of using PWM to control DC motor speed is that regardless of the speed setting, the motor still sees the full voltage, so torque is not compromised.

Changing belt speeds
I didn't want to hack a hole in the side of the mill so I devised a way to change belt speeds from the front, it goes like this.
1st loosen belt, lift flap and insert right hand in hole to move belt from one groove to the other while also turning the pulley and your left hand operates the lever
that guides the belt up or down on the rear pulley.
I made a temporary pulley support bracket to test my theory while making the bits and pieces.

10mm plate
The top of the mill is alloy so i cut out and fitted 10 mm plate for the motor mounting plate to slide back and forth on and I had .0075" runout at the top of the input shaft.
I had been looking forward to checking that as when I set the shaft up to grind the spline off the top brg mounting surface was an oval shape, so .0075" wasn't to bad l guess.
I decided to fit an outer support brg for this shaft as it is hollow and I had removed a bit of its meat and it has a bit of runout, so I used a brg with a larger ID and made a bush and bored it .0075" off centre.
I installed a dowel pin either side of the input shaft and threaded holes in the cover for jacking bolts to remove the cover.
The shaft support bush and the motor mount pivot bolt are made out of EN36A

That's very impressive, really quiet even at the high speed.
