Nice-looking work.
Funny you ask that question. I just read something on that subject in one of the Lindsay Books "Tips & Tricks of Old-Time Machinists". Fun read - 5 book set for $24.
I'll look it up and give you the answer soon. The Readers Digest version of it was that the design of the grooves depends on rotation.
