Best method for drilling 5 evenly spaced holes. In a circle.

Mark, with all due respect, you're making it too difficult.

It's not difficult at all Matt;
Actually this is very easy and it makes drilling the adapters a very quick process ONCE the jig is made... Make the jig using the rotary table to drill two holes and the rest of the process is simply drill and pin. I use this process all the time for making model car wheels and it sure beats having to worry about getting every tool move exactly right every time. It turns the process into a no-brainer, especially if you are doing a few pieces.
