So as a necessity to my in progress Ped Kentucky rifle project, I needed to build a pin drilling jig that could accurately and repeatedly drill holes for the new pins. I did this before on my drill press with my pistol build but it was much easier to hold in place than what this long rifle will...
So as a continuation of my previous post above, I have made an improved jig that requires less parts, is easier to make and more durable. It is especially easier on the smaller 1/16” drill bit. I snapped 2 bits trying to drill through the nylon bolts of the old design. This tool will also give you a wider working area than the previous version. Essentially all you need is a c-clamp and a few hand tools.
Cut off the swivel head
Cut the remaining shaft so that @ 1/8” sticks out each side
Peen the ends of the shaft so that it swages until it DOESNT ROTATE, if you swage it to much you risk cracking the casting.
File a flat on the opposite fixed pad so the drill bit will not want to “wander”
Make alignment marks on the side and top to aid with drill bit alignment
Center punch for hole
Drill hole, go slow, clear chips and oil regularly. Go into other side about 3/8”, making certain drill bit DIDN’T wander off center
Cutoff about 1/2” piece off end of long drill bit or equivalent 1/16” pin stock
Sharpen to point and glue in place
Enjoy your new pin drilling jig!!!
