Hi,

I have an used Rock Rascal that I wish to use to section rocks and
minerals.

It does not currently have a motor.

From reading supply websites, it would seem that a 1/3 hp 1725 motor is
sold for it.

Is there any advantage to using a more powerful or faster motor?

Is there any advantage of using a variable speed motor?

Thanks for any advice you might have to offer.
