Many thanks for your time... :-) I'll look into that post as well. Lately, I've been dealing with CNC software upgrades and their impact on my production of stuff.. But I'm done and back at the rounder "sine" wave problem since it applies to 3/4 of the project..

I've started to investigate metal forming programs as well.. It's sort of a rubber sheet and magnet problem..

But thanks again...and happy holidays..
