[QUOTE="Alex Wheeler, post: 3063384, member: 101859"] If your after stiffness then stick to straight flutes. All fluting reduces stiffness, but the spiral and cross spiral patterns reduce stiffness much more. I did a test with different blanks including carbons where I chucked them in my lathe at the same spot on the shank and hung a weight at 24". I measured the deflection. On the smaller contours the flutes are so shallow they dont have much effect on the stiffness of the barrel. So if you flute a #3 with straight flutes, you have not hurt it much for stiffness but you also have only taken 3-4 oz off. When Broughton was still in business the flutes where cut, the barrel was stress relived, then it was final lapped. I liked that process. [/QUOTE]
