|Build this disk sander with parts that are probably sitting around your shop gathering dust. All you need is a 1/4 hp or larger 1750 RPM electric motor, a v-pulley, switch, electrical cord and scraps of wood.|
Circle Sanding Jig
This is a handy jig to smooth the edges of rough cut circles if they have an axle hole in the center.
Assemble the pieces as shown, glue the top strip as well as fastening it with screws, put a screw in the end of the sliding piece for a stop, without this sawdust may get between the two parts and affect the setting.
To set the jig, clamp it to the sander table, measuring from the face of the disk to the center of the dowel pin for radius of the circle. Slide the circle in and rotate it against sanding disk.
