So here's the gear we assembled to accomplish the mission.
Here's a drill press made from a drill press kit where you strap your hand drill to it. It did the job, but if you have a "real" drill press you will have an easier time. This one only had a 2" throw, and we were drilling through 3.5" inch posts, so we had to finish the holes with the hand-held. Not fun when drilling 28 holes.
