Drum Sanding Jig
This easy-to-build jig transforms an electric drill into a stationary edge sander for inside curves on all kinds of projects. To build one, you need scrap 3/4-in. plywood, a short 2×4, a 3/8-in.-diameter U-bolt to fit around your drill and two 3/8- in. wing nuts. Housing design and chuck length vary from drill to drill, so we won’t list exact dimensions. Use the steps found here as a general guide for building a jig that fits your drill.
