I took a 20" - 2x2 and hammered 2 nails in an X shape on each end.
I place my arrows in the x' s and draw a dot on something at the same height as the b/h point and then give it a gentle roll, placing pressure on the arrow very near the front x. If it' s not try, you' ll see it.

I could see me trying to spin a b/h tipped arrow like a top. Wouldn' t be pretty....
