VFD bought.
3 phase motor bought.
Switches bought.
Wired together on the kitchen table and successfully pushing air around in circles
Now I need to get it on the lathe. I just bought some replacement SPA belts (SPA1557) and these fit the lathe head pulleys and the existing single phase motor's pulleys.
But the shaft on the outgoing motor is 19mm and the shaft on the new motor is 24mm, so I need new twin pulleys for the new motor. Turns out there are as many acronyms and widgets in pulleys as there are in brain surgery...
So looking at bearingboys, I think I need one of these (three grooves - they don't seem to have a twin groove):
And then it seems that I need to sort out this "taperlock" thing... So it's a 2517, and I reckon I need a "2517-24" bush to fit the 24mm shaft?
Is that correct?
