The Family Handyman
Use this simple wood jig to turn your table saw top into a horizontal drilling station for drilling repetitive holes. Cut a strip of hardwood the same width as your miter gauge slot and screw it to the bottom of a piece of 3/4-in. plywood. Cradle your drill between pieces of 2×4 fastened to the plywood. Strap your drill (a flat-top drill works best) to the 2×4 with plumber’s hanger strap.You may need to use tapered shims to get your drill bit parallel to the saw table. Now you can slide this jig along the top with the strip below riding smoothly in the miter slot. When you drill your wood, be sure to clamp it to the top.
