Here is a quick video of showing how I can use MoI to get some of the shrink and stretch data needed.
I cut the video off because I was looking to get great results and went down a rabbit hole. But I realized I was just grabbing data that was "too simplified" for when I am converting flat to circular. If I was great at this math, I could probably get pretty exacting data. In the past, I would ask Michael for help and he always came through, but I was basically making him teach me geometry (Not fair)
There are a few guys in here that may want to play along to try to achieve. But with that said, even the results I can get by "Faking it", are within .04 inches! If I was bending and welding, I could fix that with a hammer or a grinder. The nuclear sub guys would laugh me out of the shop!
