After experimenting a lot I’ve come up with a sanding disk that works pretty well. I don’t know why someone didn’t come up with these before. The disks themselves are 3/8” in diameter. They’re made out of foam with 3M sandpaper laminated on with an adhesive backing. And they fit onto a custom mandrel.

This sanding device is made to be operated at a slow speed. The recommended operation speed is 1000-1500 RPM’s. A hand held screwdriver on high is a good example of the speed that is recommended.

They work good for fast removal in flat spaces and can be maneuvered around contours and into cracks. I make these with my CNC machine.

Here’s a video of the disk in action. It shows me sanding red oak using a 120 grit sanding disk:

I made some and am selling them on ebay but the link will expire one day: http://www.ebay.com/itm/181518996877...84.m1555.l2649
