Expander Wheels and Bands
Now you have another option for smoothing irregular surfaces: The Expander Wheel. The Expander wheel is a rubber wheel that expends when spun by to hold abrasive bands in place, yet stays flexible enough to conform to slightly curved surfaces.
Eastwood carries all the bends you'll ever need too; everything from 80 grit grinding to 4000 grit finish work. With the right band, and they are quick and easy to change, you can ever do jobs you used to need a grind stone for.
