Baldor buffer

[Carquest]

Looking at buying a Baldor buffer, just for hobby work. I see there is an 1800rpm version and a 3600rpm version. Which one would I want?

Thanks

Your choice is largely guided by the size of wheels you’re using and the material you're polishing. Like drilling or turning, the important measure is the speed of the tool at the working surface (usually expressed in surface feet per minute).

For aluminum polishing, something in the range of 5000 to 6000 sfpm is common; for stainless, that gets upped to perhaps 8000-9000 sfpm.

If you’re doing jewelry, for instance, you’ll usually be using small wheels in the 3” to 4” diameter range. Buffers for that work are usually around 3250rpm or so to get into the 3000 sfpm range, which is suitable for those soft metals.

If you’re using large wheels — say, in the 10" or so category — to do things like aluminum manifold polishing, a motor in the 1800rpm range is more appropriate to get the right SFPM.

It's really dependent on just what your hobby is.

The one I’m looking at uses 8 inch wheels, so the lower rpm would be better for aluminum and chrome polishing?

Or you get a used 3phase Baldor Buffer ( 3/4hp or more) and an inverter off Ebay to give you any speed you want.

Or you buy an expensive 2 speed one from tptools.
