2.5 mil is 0.0025". What I mean is that I can just barely slip a 2 mil feeler gauge under the rod in various spots. Not much of a bend angle. I was only wondering just how critical all this was. If "fixing the bend" is acceptable, then I think that I will live with what I have. Don't know how any one is going to "unbend" a rod any straighter than what I have. Thanks.
