    I'm looking to replace my Eastwood 10" 1 HP dual speed buffer with a Baldor (my Eastwood has broken two times already). I've got a bunch of new 10" wheels that I bought right before it broke most recently (of course), and I'd rather not have them go to waste. Baldors are beasts, but I'm wondering if it's possible to run 10" wheels on a Baldor made for 8" wheels at 1800 RPM with 1 HP, as they're cheaper than their 10" options, and there's sometimes more 8" buffing wheel options than 10". I know centrifugal force quadruples as you increase diameter, making things less safe, but I'm wondering how much that influences a small 2 inch jump running at just 1800 RPM. Any insights?

    I would probably just do it. I am guessing the best answer will be from the manufacturer.

    I've done the reverse of what you're asking and had no issues. As long as it fits on the mandrel properly and you're not buffing under heavy load (doubt it) you should be fine. Might have some issues applying compound if you like to do that on spin-up of your wheels, but once underway I can't really see it being a huge issue.

    You should be OK as long as there is enough clearance between the bench and the shaft to accommodate the larger wheel. The Baldor had more then enough motor to run the 10" buffs. Have fun and be safe.

    I've got 2 - 8" Baldor buffers running 10" wheels @ 1800 RPM and they work great. Plenty of torque to rip a knife out of your hands. ;)

    I misspoke!!!

    I actually have 6" buffers (not 8"!!!) running 8" wheels.
