That works. But I don't own a v-mic in order to do it right. Is there
another 'standard strategy' for measuring odd-number-flutes' diameter?

I've been going through all my old texts, and they all show a v-micrometer
as the preferred method. I was hoping for some old 'shop lore' method.

I've owned a V mic since I was an apprentice back in 1993 but Uncle Loud is still too cheap to buy one? Are you ****ing kidding me?

Uncle Loud continues to show he would step over a dollar to get to a penny.
