but once you get the concept of what you are actually doing and why, the process will get easier. It's still alot of work. I have a write up on file if you would like me to send it to you (via snail mail). I think if you googled "cam" and "degree" or "degreeing" you'll hit the jackpot on a number of step by step methods (there are different ones). Sorry, I don't have the time to try the search, but I'm sure you can find a good explanation. I'm sure AJ would be more than happy to post the step by step method we used, because he has no life :-) ....that's going to cost me. Good luck, Mark
