    Given that all I need is the get this thing rolling from stationary, it wont need to be "ON" for more than 1 or 2 seconds, so the chance of burnout in that time would be unlikely, would it not?
    As the start cap on an SP motor designed with an auxiliary cap is usually energised for less than a second I would start by trying something like a quick tap.

    Hi Mal, Guys,

    .
    My bad ! I've always understood that a single phase motor with a capacitor permanently in series with one winding and no method of disconnecting it to be a start capacitor. Since its sole purpose is as you say to determine the phase shift between it and the run winding.

    A side benefit is that the motor is easily reversible !

    I have a multitool with a 200mm contact wheel it is very low to start so I just spin it then switch it on yes I know it is not correct but it has been working this way for at least 20 years
