Note/For visual effects not all of the safety devices have been installed or utilized on the OJJ, regarding the individual presentations. Be diligent when operating woodworking machinery, use push sticks when appropriate and wear safety glasses.(I reserve the right to be wrong. Should you prove me wrong, I reserve the right to change my mind.) The Original Jimmy Jig's innovative design can be adapted to any existing table saw, large, small, old, new and any style bench-top model.The Jimmy Jig is a table saw extension support platform which handles plywood to 4ft. on centre of cut, a one man operation. Addresses the table saw's short comings, in particular the dangers of kick-back with the innovative up-front safety devices. Doubles as a router table by attaching the router in the aperture, a crosscut sled can be another addition. The Jig is light weight, removable, portable, ideally suited for small workshops and on site construction and finishing work. Eliminating the need for permanently mounted out feed and side mounted support tables.
