To make the JET rotate in the correct direction requires that you open the VS controller to reverse the motor output wires.
I also added an RPM display using a simple Hall Sensor I got on Amazon, that took a while to mount in a Radio Shack style elect box with the associated wiring.

THEY GIVE AN IDEA OF HOW I HAVE A SWING ARM WITH LOCK FOR THE BELT CHANGES. ALSO, A CLAMP TO THE MOTOR SO IT CAN BE MOVED UP OR DOWN FAST AND EASY. THIS IS WELL WORTH THE TIME AND EFFORT TO BUILD FOR MY HOBBY SHOP. I CAN'T WAIT TO GET THE 3/4 HP ONE IN PLACE AND WORKING.

I had to make a minor modification of the motor mounting bracket by enlarging one hole.
Other than that no problems.
the speed ranges are much wider than spec'ed. Power seems good.
For my lathe the motor needed drilled but no big deal.
I have only changed the belt one time and that was for testing the speed range. Low was about 250 rpm to 2000 rpm, middle belt setting was about 450 rpm to 3550 rpm, and high was about 650 rpm to 4700 rpm. (only once, a big NO NO) Above 3800 rpm will over heat the bearings and create damage. I like the time savings and versatility.
