[QUOTE="ntsqd, post: 1720124, member: 93138"] I was curious if there was any density advantage in SS over carbon steel. Normally SS is just slightly denser than carbon steel, but in looking specifically at 416 SS and 4140 Carbon Steel the denser metal is 4140, by .002gm/in^3, so there is a difference but it has no practical impact. FWIW, by an admittedly rough CAD model, fluting (25in exposed length [i.e. less the tennon] X 1.25 cylinder, .224 Bore, 6 flutes @ Ø.375 X .25 DP) is a ~13% increase is surface area and a mass reduction of ~19% That's pretty much inline with what I recall of my previous looks are fluting. Doesn't seem worth it to me, but might be for others. [/QUOTE]
