*I'm trying to revive this thread. Never got any takers the first time.*
So, I've been looking all over the place for any knot resembling the two knots on pages 238 & 239 of the TBB vol.2, in hopes that I can find clearer instructions on how to tie these knots, but I haven't had much luck. I did find a knot, called a Blake's hitch, that is similar and may even work, but I've had a horrible time trying to tie it while bracing the bow.
I'd really appreciate it if somebody could post some pictures on how to tie & use these knots. I suspect that there are at least a couple of knowledgable bowyers, besides Tim Baker, who know how to do this. Badger perhaps?
