Looking for a stout, quality set of rubber mandrels, for sanding tubes. This is for using in my drill press, to sand radiuses in .060-.080 sheet stock. Was hoping to find something better than the el-cheapo 1/4" shank ones that are only an inch or two long. Thank you

I use the ones on my oscillating sander with a bolt, some washers and stop nuts.
Check with any of the woodworking shops for the rubber bodies and the sanding cylinders.

I have one for my Shopsmith that is 2 1/4" Dia. by 3" tall and has a 5/8" hole and setscrew to mount on the spindle shaft of the Shopsmith.
The problem with this may be finding aluminum oxide sleeves that size. The paper Shopsmith sells for it is garnet.
One of my abrasives catalogs notes a Sears 2 1/4 x 3 inch drum but they do not sell the paper, just the drum with a 1/4 inch shaft.
Rockler at www.rockler.com (http://www.rockler.com) sells 3" x 3" drums that are made to mount on standard motor shafts 1/2" and 5/8" as well as a sleeveless drum that has a 1/2" shank in 2 x 3 and 3 x 3.

These ae called "drum sanders". You can buy them in sizes from 1/2" up to 12". www.leevalley.com (http://www.leevalley.com) has several different quality levels on theirs (Good to Spiffy).

I ended up finding the individual 3" rubber drums, at Sears. A trip to the hardware store for some bolts, nuts, washers, and I'm set. Made for a nice stout set of 1", 1.5", and 2" drums, in a 3" length. All total, with a few sanding drums each, cost $40.
