No, not really. I have done a job that required me to compound angle the head to drill a 8 hole bolt circle hole pattern and drill holes on a machined face on an angle and had to hold pretty tight true posistion. So the face of the shaft that required the bolt circle was angled, and I had to kick the head in both axis to a spicific calculated angle. for each hole, all 8 holes at different angles, if that makes sence. I had to use an endmill to create a flat to start the spot drill, then drill undersize, bore with a small end mill still under the finished hole size, then ream to size. All 8 holes intersected a thru the shaft center hole. So if I went to deep and hit the center hole sides It was scrap. I first did a replica piece I machined out of aluminum to proof my method out, then machined the 6 Phenolic parts. Didn't scrap one piece.
