Regis, It is easy to install the Oak Park jigs to your table. Chuck up the 1/4" bit, set the 1/4" jig over the bit so the bit is roughly centered in the jig opening. Place the 1/4" set up bar next to the bit, push the jig so the set up bar is snug between the bit and fence, drill the two holes in your table. Follow the instructions that come with the jigs for complete set up. The jig can be at any angle on your table. Following this process you end up with five 1/4" holes to allow you to perform all the functions the jigs are capable of as seen in the photo below. These holes will have no effect on using your table.
