Hu and Rekd, Thanks for the responses.
Gave me a little food for thought. I hadn't considered using the G83 Peck Drilling cycle, seems like a good candidate.
What is L, W, X in these cycles?
Hu, I know you as the BOBCAD guru for the BC forum. I use BOBCAD V18. If I can't get one of these canned cycles to work could I commision you to write me a script to handle it??
