More...!

It measured 83#@43" – and it had still a lot of more life remaining.

Here is 45" draw.

Hamish:
Lol!

Looks like maple and cherry is a good combo.

BowEd:
Interesting experiment.Those are every day Howard Hill poundage shooting draw weights.
Your bow looks afterwards like a sinewed D/R  to 6.5" red cedar from a stave I did years ago.When they go they go off with a big bang.
The hidden culprit that can infiltrate a black cherry many times with time surviving when being over stressed is that it'll chyrsall or fret on the belly.
I have an awful pretty 64" sinewed on only the working limbs black cherry holmgaard that chrysalled just a little after a couple thousand shots through it.Still shooting it though and it still looks healthy holding 4" of reflex at rest.
If a person is paying attention to the draw weight as you pull farther and farther on the tillering tree and the draw weight starts decreasing that's the sign it's degrading and getting ready to blow.
That sure is a heck of a long draw though.

The interesting thing was that there were zero, not a single fret or chrysals, nothing. It just took set, about 4–5".

But, we are now at 45" draw and it is still going strong! But how far?

BowEd:
You shoot em long enough that way over stressed and it'll happen even though it does'nt show immediately.
