|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.
Put an Old Table Saw to Use
A table saw can also be converted to a disk sander, this will give you the added advantage of being able to tilt the disk and make use of the miter gauge and slots in the table. Many people make use of their old table saws as dedicated disk sanders.
