FEATURE PROJECT Index System What's unique about this drilling guide is an index system that's used to establish the spacing of the holes for the shelf pins. This system locates the holes in two directions. It sets the distance in from the edge of the workpiece. And it ensures identical spacing between each hole. To make this work, there's a simple mechanism that locks the index block on the threaded rods. LOCKING MECHANISM. The key to this mechanism is a pair of eye bolts. Each eye bolt fits in a slot in the end of the block, see drawing. The “eyes" of these bolts provide openings for the threaded rods to pass through, see detail 'a'. This way, when you tighten a nut (and washer) on the end of the bolt, it pulls tight against the rod and locks the index block in place. Before cutting the slots for the eye bolts, it's easiest to drill a shallow counterbore for a washer centered on each end, see Fig. 3a. Then just cut the centered slots so the eye bolts fit snug. There's one more slot to cut. But this time it's on the edge of the index block, see Fig. 4. The purpose of this slot is simple. It slips over an index pin (added later) that's placed in the very last hole you've drilled in the workpiece. This automatically indexes the drilling guide for the next hole. To prevent any “play," it's important to cut the slot so the index pin fits snug, see Fig. 4a. (I used a VZ-dia. bolt for the pin and snuck up on the width of the slot.) GUIDE HOLES.
