Thread: full hollow blade to polish with a buffing machine

Wouldnt cutting the power back on a buffer make it run slower? Id think it wouldnt be too hard to make one variable. Or am i wrong? Sorry. Dont mean to high jack the thread. Back to buffing angle.

Would take a variable speed motor or fry a regular one.
I do have a craftsman grinder I put buff wheels on and it maxs out at 17 what ever what ever. Slow is good and less pressure on the wheel is better. Hot is never good so use water to cool frequently.

It doesn’t really matter, smaller wheels might be safer and generate less heat, but both work and produce the same results.

I have both, a 1750 Baldor and 3450 rpm, no name and a Harbor Freight buffers. The finish is the same.

No issues buffing full hollows, on either buffer, use common sense and quench at the slightest feeling of heat. I use 4-inch wheel on both, have for years and never had any flying across the shop.

There are variable speed buffers out there, just never have used one.

Hard to beat, a $30 HF buffer.
