I threw together a thickness sander today....... it worked! Well sort of, I was 1/16 off over a 11 1/2 inch board. Which was spectacular considering I only used a tape measure to get my sizes and I only used junk I had laying around, like 2" PVC for the sanding drum, plywood from on old table, and a 10 yr old 1/3 hp drill press motor. It was great! And man it made a mess in the shop! dust everywhere! I did It as a test just to see how hard it would be, its simple! So now I'm saving the bucks to build a "real one" I figure an Aluminum drum and table, maybe a 3/4 or 1 hp motor. And definetly a dust collector! Parts at the extreme most 150 bucks for a 16 incher. of course I already have the dust collector parts, pulleys and sanding belts. I just have to figure out a "perfect" height adjustment mechanism..... any ideas?
