So when we get moved I am planning on setting up shop and had an idea. A sewing machine pedal is just a rheostat that is very convinient. Has anyone thought of using one to have ultimate control of the speed of their buffing wheels? It may work for a grinder too but I think it may leave the grind a bit uneven since the cutting would be drastically different.
I think you need to look at the electrical requirements as well as the type of motor.Quote:

I wouldn't suggest that on a high quality buffer without speaking with an electrician about it.
I'm make the thing from scratch I think... Maybe even use a sewing machine motor.
I have thought about using the sewing machine rheostat. However wattage on it is not enough for my buffer.
Not sure, but I don't think a sewing machine motor has the guts for buffing. But it is always worth an experiment.:)Quote:

I bought a foot switch for use in a dental lab -- it's heavy-duty, and can handle the amperage associated with the use. It cost a bit more (~$40, IIRC), but it's certainly proved to be worth it -- both in terms of RPM control and safety.
