I wanted a way to sand outside corners smoothly and quickly. Looking through one of Danny Proulx’s books I came across his plans for this DIY version. Went scrounging at my local machine repair shop for a used motor with the right RPM and found one for a bargain price. Everything else is 3/4” plywood put together with pocket screws. There is a dust collection port under the motor and I wired it to a simple ON/OFF light switch.

The hardest part was fiddling with the actual plywood disc and the cheap pulley to get it perpendicular to the motor shaft. If you had access to machined pulleys they would make a better choice. You also want to use the flattest piece of ply for the disc.

On the piece of plywood is a adhesive backed piece of hook and loop. And then you just slap on a felt backed circle of sandpaper and voila!

I started gathering parts this week to build me one these. Congrats on yours! I was snooping around for ideas and dims.

I’m going to try a “Quick-Disconnect Bushing” from McMaster-Carr in lieu of the pulley, McMaster P/N 6086K197. Don’t know if it’ll work or not, but it only costs $12.25 so not out much if it goes bust.

Simple yet awesome. I’ve got a couple of extra motors laying around that I was trying to figure out what to do with them… here is my answer. Very nicely done.
