I have a air filled drum sander I got from industrial abrasives and they no longer sell them. it is 2in diameter. I've searched online and can not find the same one anywhere. Grizzly sells one that has a handle on one end and the other goes in a drill that may work in a drill press the same but not sure about the handle.
Any one have a source they would like to share
Thanks
Terry
Woodworker Supply has a few sizes of air filled, sanders can't remember the sizes etc off hand. Check out their website, might be what you are looking for,
