I have been intrigued by the Sand Flee and while I understand their purpose to a small degree, I am curious about actual users opinion on the usefulness of the tool. It is not a tool that I feel an urge to spend money on, however, I happen to have a 3" dia by 46" long aluminum drum with a rubber coating, bearings at each end, and a gear attached to one end. The piece was from a large scale plotter that was thrown away by my engineering firm. I kept it thinking I would use it for an out feed table roller or something, but now I am considering using it to make a sand-flee type sander.
Any input?
