Hi,

When I started Buffing my lathe projects on a small buffing wheel, I really liked the finish but it was taking too long so I am going to mount a Beall Buffing system on a Bench buffer, for better results, but I am torn between two models becaues of the motor speed: do I go with the 1725 or 3450 version. I was looking at the Jet Jsb-10 Buffing And Sanding Machine W/Stand. I was thinking that I needed a faster speed because when I used my Small lathe mounted buffer the top speed was 2500 rpm. Now when I read up on the Jet Buffer/Sander I read that the the sanding drum was only rated to work at max rpm of 1800. So I would like to know what other people would do. The reason I singled out the jet was that I there is a similar unit at work (8" Grinder and it is nice and heavy), the stand looks like I could add some weight to the bottom to keep it sturdy, and I have about $200.00 In Amazon.com Gift Certificates (Fed Ex Reward points add up quick). Currently the 1725Rpm model is $375 and the 3450 rpm model is $450

Thanks,

Greg

Speed is not the objective when buffing. Speed=heat.
Ideally, you want around the 1750 rpm mark, but this depends on the wheel size. The larger the wheel, the higher the rpm.
When buffing, the type of wheel and compound are what determine how long it takes and the outcome of the final finish. Use very light pressure on the wheel and let it and the compound do their job.
Buffing is just like sanding, start coarse and go down through the finer grits of compound.
There is a cut stroke and a color stroke. Use those in combination with crosshatching and the result will show.

The Beall system reccomends the 1725 motor speed in the literature that comes with it. Just picked one up this weekend but haven't got it out of the box yet other than to look at the instructions.

I agree, actually is wasn't speed more than it being too small and because it was attached to the outside of the headstock I was limited on space and If my piece slipped it would hit the tapered threaded shaft that the buffing wheel was on, I would nick it and have to start all over.

Thank you JD and Plastyk for the info, guess I should have read the package, if only I can find what box in the attic I buried it in.
