Here is a quick update. I was able to do some roll thruster test drills on an old 1/96 scale CM. I found a technique that seemed to work to give me that low angle drilled out hole. I drilled out the thrusters on the Dragon CM and it seemed to work just fine.
I think they turned out pretty well. I’ll keep that in mind for the next CM build. On to the Service Module in the next update.
