Tricks of the Trade continued from page 28 Drill Spheres Easily I recently installed a bench vise, but was disappointed by the skimpy plastic caps on the ends of the wooden dowel handle. I decided to upgrade them using a couple 2"-diameter wooden balls that I bought. Fitting the balls onto the dowels proved surprisingly simple with the aid of a setup that is so simple it hardly deserves to be called a jig. First, I outfitted my drill press with a Forstner bit of the same diameter as the dowel, then drilled a hole through two short lengths of scrap, offsetting the holes toward one end. I then trapped the ball between the two holes, shimming between the non-drilled ends of the scrap to orient the two pieces roughly parallel to each other while clamped to my benchtop. Now I was able to bore a hole in each ball using the same Forstner bit in a hand-held drill, guided by the holes in the scrap. The beauty of this setup is that the scrap guide pieces really don't need to be clamped parallel to each other or square to the benchtop, as the exaggerated angles in the drawing show. As long as the ball is seated firmly between the guide holes, the drill will travel through the ball's axis. For best long-grain glue strength, I made sure to bore the hole in the direction of the ball's grain.
