Well, I got the mill outfitted with a VFD today. I used a 2 hp motor, 145T frame, 1750 rpm. The motor bolted right up after I enlarged the holes in the base by 1/16”. The shaft is 7/8” where the old motor was 19 mm, so for now I picked up a single 3 1/2” pulley from tractor supply. I don’t have a boring bar large enough to bore out the original step pulley. I was able to reuse the belts that are like new so that is good.
It is scary quiet running. I’m deaf in one ear and can’t hear out of the other so it’s hard to tell if it’s running. While I was at it I put felt between the belt lid and the top frame so the lid doesn’t rattle now either. I plan to stop by Fry’s tomorrow and pick up a red and green LED to put in the run station to show green for running and red for not, can’t hurt to have the visual. I don’t like the run station but it’s what I have for now.
The control is very basic. Forward, reverse, stop, and jog forward and reverse. I have a MachTach for it that will mount under the DRO. The speed pot will be in the box with the MachTach. I used a Delta VFD with a brake resistor.
I hope to put the tach together by the end of the upcoming weekend.
It has come together very well, I’m happy with it.
