Jig holds panels on edge

Clamping any long, narrow object on edge requires a door buck or other specialized equipment that most home woodworkers just don't own.

You can clamp large objects vertically with these two right-angle jigs. Glue and screw together these jigs from ³⁄₄ " plywood. Place threaded inserts in your workbench at regular intervals, and fasten each jig to the workbench with a thumbscrew and washer. Just secure your workpiece to the front of the jigs with C-clamps, and you'll be ready to work.
