Thread: Idea for a buffer

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.

I picked up my stuff on the cheap from Harbor Freight just to use on my own tiny collection. I got their router speed control device and it works fine. It might shorten the lifespan of the motor but I'm not worried about it.

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.

I have a Delta Variable speed buffer/grinder. I use the lowest RPM's for razor work, (buffing) and higher RPM's for Grinder/Sharpening type work. The variable speed is invaluable to me, and the quick release mechanisms on the wheels.

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.

This is the one I've got. Here's a link to where I bought it

As usualy. You have again better choice behind the pond.
