You got speed control? If not be veeerrry careful, or use a smaller wheel. Anything over about 1000 RPMs with a wheel that big is gonna burn vulcanite in a hurry. Found that out the hard way.

Not yet, but I'm planning to put a dial on it next weekend.
Thereafter I'll be experimenting with speeds and angles, etc., before putting anything nice under it.

Was thinking about an 1,800 rpm grinding/buffer
I know 3,600 is a no-go
I have seen 1,800 recommended for pipes, but based on this I guess not
Can you roll with an 1,800

At full power this motor runs at 1725rpm and was recommended to me by a pipe maker whose work I admire a lot. I'm going to put a dial in just for extra-delicate items.

With buffers, the real thing that matters is surface feet per minute. This has to do with the increased speed at the buffing wheel contact point due to the increased diameter of the wheel over the spindle.
The math for it is: RPM x Diameter x 0.2618 = Surface feet/min

My personal experience with stems, trying to avoid rounding off buttons and changing stem profiles, is an SF/M of about 1500 to 1750.
I ran a 6" wheel at right around 1000 RPM. If you were running an 1800, I would probably go with a 4" wheel. You could run a bigger wheel if you use an inline router speed control. It's worth noting that a router speed control/potentiometer type speed control will only work on a motor with brushes. Speed control for brushless requires a PWM controller.
