Greggor.. Should be running at 1750... So a two inch pully on both the motor and arbor for you polishing disc if your using a 1750 motor.      [/quote]

it is (I believe) a 1750 motor and it is hooked up directly to wheel so it's turning the same   -   but  -  that is way too fast & it slings polish mixture  off before it has a chance to do any good.  so i thought i read   (Bobby1 ?) that polishing wheel should be  3 or 400 rpm.

so I am thinking I have 2 choices:  i: less expensive = build pulley system  with variable pulley.

                                                     2:  better  =  find variable speed electronic motor.  If I do this, I am not sure what power I need.
