Wouldn't you be better off threading the body for standard shafts? You're
going to ruin the shafts anyway, they're expendable. I think there are two
standard threads. Stainless isn't dense enough, use tungsten or depleted
uranium.

I'd like to try and turn some single-piece darts on my lathe using some SS
rod. The turning should not be a problem but I need to know how to cut
the 4 grooves in the flight(plastic "wings") end. Any ideas?
