ACCURA 8" X 9" Pneumatic Pump Sleeve/Bag Sander Great for Contours

I was looking for a pneumatic drum sander like this one, they aren't readily available. I purchased it and set it up as a attachment to my 6 inch belt sander, my sander did not have a disc. Some might say it was a major retrofit because I extended the drive shaft of the belt sander and added some bearing pillow blocks for support, If I had to do it again I would have bought the 6 inch in stead of the 8 because it would have matched up better. The set up required the purchase of; a 3/4 inch drive shaft, a shaft coupler, 2- 1 x 3/4 bushings, and 2- 3/4 pillow blocks`
