Disc Sander

1400rpm direct drive works really well and I made the basic structure with MDF, plywood would work well in it's place:

This is 6" and must admit that even with this you have to be careful not to burn the wood. I really wouldn't want to go much faster than 1400rpm. Have used this for a number of years now and it has served me well. I've put more images on my website to help with the design, but you will need to size the basic structure for the motor you have and the disc size. The motor is 300W and if you use it hard it is still possible to stall it with just a 6" disc. I've also added a link to a supplier of the sticky backed discs in the UK
