My original question is at the end of this summary.
I received the following two responses:
** Response one **
I do the same thing you do with the surface controlling the tool axis normal to the part. The other option I use is to create an axis thru the center of the part and the beginning of the trajectory when defining axis control. This also works. What I find works easiest using the turn/mill is to use 4x surface milling using surface isolines and just pick the surfaces from the model. It's quick, easy and you don't have to create any trajectory curves, or define axis control....
** Response two **
Are you sure it was trajectory? It possibly could have been Surface sequence in 2001 that you were using. Surface seq allow pivot axis and pivot curves.
** My comments **
After reading these, I went back to the help literature. Sure enough, the portions dealing with 'pivot curve' axis control stated that it is available during surfacing sequences. I had used the 'search' function and overlooked the fact that it took me into the surfacing section and not the trajectory section.
Here is the kicker: Once we had the program ready we realized that the new machine we were programming this for did not have the G107 (Cylindrical Interpolation) option turned on. It was an oversight on the purchase agreement. We had to do quite a bit of code massaging to do the part with a simple C axis.
Once again, thanks for your help.
