I thought to myself, hell, I can make one of these for under ten bucks. All I need is a $8 combination set of adjustable spindles (1/2" - 2") with sanding discs (sold at the same store), and I'm set.
The spindles fit in my drill press and are recessed into a piece of wood (for convenient and accurate sanding), which is bolted to the press table. I even got crafty and built a fence to fit on the table so that I can precision sand if I want.
And the $120 I saved will buy a little Heineken to quench my thirst after a hard days work.
