I liked the bead sander posted by Filinvested. And I came across a old blender that I considered using but it was too small .
I had a old 1/2” shaft motor
1/2”x 2” pulley with one flat side -$6.
5” plywood circle
Velcro from a craft store $10. A yard
Found plastic bucket
Found Pyrex lid that happened to fit my bucket
I cut some foam to line the inside of the bucket and fill in the small gap between the plywood and bucket wall.
Then I mounted it on a plywood strip to hang on my wall. It seems to work pretty well so far and you can hardly hear it run. I really only bought the pulley and the Velcro special for it. I bought a assortment of hook and loop sanding disc but I have a sander that uses those so I’m not counting that. Maybe this will help someone and when I completely run some beads I’ll post in the projects.
I drilled a 1/2” hole in the bottom of the bucket and 3 holes around the bottom edge to release dust and give access to the Allen screw in the pulley.
I epoxied the plywood to the pulley and put the Peel and stick Velcro on the top.
