Thanks Rich - yeah, the hula hoop.... that very stave is the reason for my tree finding excursion yesterday. I was trying to get that dang thing to cooperate and realized, its tougher than I am. I decided to save that one for a day when I have far more will
. Besides, these oak are much closer than the VM.
I finally found the picture I was looking for - its the one in TBB 1 - There are some hand drawing pages of native bows - I don't have the book here, but if I recall correctly its the right-most bow, on the left-side page. It has flipped tips and similar in dimn as you describe (if I recall correctly).
That does help, thanks Rich! and you're right, that cambium is some perdy stuff.
I'm looking forward to working on a nice straight piece of wood for a change!!
