problem

I hope this question is not too simple for any of you. but I am have trouble with modeling a ring in 5 axis like the video on you tube. my tool paths are not to the center line and the paths are not touching the surface of the ring . any ideas ? I am sure it is some thing very simple that I am overlooking. the help menu seems to not have every thing in it ie. I was trying to look up the instructions for drive surfaces, is there some place to go to look all this up?

i hope this link will work
