I made this simple jig when I was making some cribbage boards and wanted the holes to be very accurate. The fence is fixed to the base. The piece of scrap on the right side has a hole drilled in it that I chiseled out to receive a bolt. I then used a threaded rod as my advance mechanism. The rod itself has 16 turns per inch and if my memory serves correctly the holes are spaced 3/8 inch apart (6 turns) and the groupings are 3/4 inch apart (12 turns) and the holes were 3/16 inch. The horizontal movement is adjusted by moving the entire jig from front to back. It still takes a long time to layout the design but at least you know your final product will be accurate.
