Damn, I have been using these types of bars from the 6 inch to the 36 and beyond, and not one time in the thousands and thousands of strokes, did it ever occur to me to check to see if they are flat, I guess if I could see a twist in it, I might think about it, but 1/32 over a distance? What freakin model are you building where a 1/32 matters over a given distance?
