I'm the current obstacle in the road to progress. I wanted to make the throats in one peice and I can get them geometrically correct but the tool path and finish is unsatisfactory to me. Long thin undercut tools and deflection make the internal corners not pretty. The horn should be cake, the throat has been hell.

I have sent the throat that I own, the Solidworks model and my program to a friend of mine who is way smarter than me who teaches CNC at a university and has the same machine as I do with the addition of fifth axis. He is going to run one and see if he can get me a four axis tool path that will run. If not I am just going to make them two peice, which should be a snap, it's just not how I want to do it.

I have none of the drivers.
