    Datum Surfaces on Stocks

    G'day there, but of a basic question, but after doing one repair on a stock which required drilling through the stock I found it hard to find something use to ensure the drill went straight through the stock. Essentially with the drill press and the curved sides of the stock it was all guess work. I know I could use some of the surfaces inside the stock to gauge if it were perfectly upright partially but not entirely, and even then the surfaces in there are tiny and hard to use, and even the it was impossible to keep the stock in one place. In the end I went by eye and it worked, but I don't want that.

    Being an inexperienced person with no real workshop time means this is probably a dumb question for the veterans on here, but any help is appreciated.

    Make a dimple (center punch mark) where you want the drill to come out and where you want it to go in. Make a taper / pin and mount it to your drill press table. Move it around until you get the tip of the drill bit perfectly centered on the taper when you run the drill press quill down. Lock the taper in place - I made one from all-thread rod, and use a nut with washer above and below the center hole in the drill press table. Set stock with punch mark on the taper - start drilling on the second punch mark. Go about 1/2 way. Flip stock over and place your drilled hole on the taper. Drill into the second punch mark. The holes will meet. You will have entrance and exit holes exactly where you made the punch marks.
