I didnít see exactly what you were buffing. Is it wood, a CA finish, Acrylic, or some other finish? Buffing compounds and wheels vary depending on what you are buffing.
I also have a soft flannel wheel with nothing on it.....no compound. With the Beall 3 wheel system, each wheel is buffing while applying the compound/ wax. I use a clean wheel for my final buff to help clean off any residual wax and provide the desired sheen. Many times, I will use a wipe on coat or two of Danish Oil Finish or Tung Oil Finish on some wooden turnings and only buff with the clean wheel.
Hope this helps.

I'm guessing that's because the wheels are spinning between two points, rather than being directly attached to a shaft, where it won't flex and come out from between those two points.

Most buff motors spin at 3450rpm, there are some that go to 3600rpm, and there are some that are two-speed and variable speed. Those usually go down to around 1750rpm.

We ran 5hp buffers with 24" wheels, and if I calculated it correctly, that is almost 21,000sfpm. It's not the speed of the wheel, it's the method of buffing. The faster the wheel spins, the faster it accomplishes the task, and the faster the part needs to move across the wheel. Lingering will create heat, at any rpm/speed, and cause damage to the part. Too much pressure against the wheel causes heat.

It doesn't really matter what speed the wheels spin, the method has to match and compensate for it. Using slower speed and/or a low hp motor, the method will be different than a high hp motor and/or higher speeds.

I now use a 1/2hp buff motor with 8" wheels. I buff parts for local car guys periodically. I also buff casket hardware on occasion.
