Mike,
Maybe I'm too simple minded, but couldn't you just "plug-and-tap" it?
Or are there other considerations beyond my imagination.

As Webb pointed out, they scratch real easy and since it's just a thin carbon fibre tube, you have to watch that clamping preassure.
I made tapered Delrin collets for the Revo shaft. I made them longer and thicker than my usual collets, to make sure I distribute that clamping preassure on as much surface area as I can.
I'm just using a 3 jaw chuck, a 6 jaw would be much better suited.
Running a 3/8-10 tap through the existing hole seems like a bad idea. Radial is .312" regular 3/8-10 is .302"
