[QUOTE="64FJ40, post: 1254025, member: 16057"] Like I said, I can see the overall weight argument if that's the case since the middle material adds very little overall strength in comparison to how much weight is there. For a race car, I guess I can see it. That was the part I forgot to add to my previous post - and I don't know the answer so maybe someone with metallurgy experience can comment. Is it possible that exposing the interior surface of a gun-drilled shaft may increase the actual amount of material that can be treated, assuming heat treatment has some effective depth?? So that a 10% loss in strength can be overcome? [/QUOTE]
