That's a very good looking bow. Just a bit curious, what was wrong with the wood?

Yeah maybe, but I got the impression that he sinewed it because he thought it wouldn't hold up otherwise. I don't know, just curious is all. It's entirely possible that I misinterpreted his post.

Anyway, that's some good looking finish work. I like the two-tone look.

I dont know how one could think hickory wont stand the stress, i have some test piece of hickory (roghly shaped bow) and i can bend the limb i one place almost 90 degrees and only few splinters appeared, but still almost whole thikness of wood is in one piece,  just bent. I was amazed about the characteristics of this wood. I dont even see the possibility of breaking properly designed hickory bow... but i can be wrong since ive made only 3 hickory selfbows...

I agree, which is why I was curious. Hickory is about as tough as they come.

Excellent! I love the unbraced profile. It's almost the exact inverse of the braced!

That looks really nice. I like the reflex when unbraced.

Super bow.  :)
I'm interested in your sinewing technique. Did you heat the stave into all that reflex before sinewing or did you semi tiller it first then reverse brace and sinew it?
How long did you let the sinew dry?
Oh and what''s the humidity like where you live?

I heat a 5 inch reflex before sinew. i dont semi tiller. i start tillering after sinew full dry. sinew dry 2 months in house temperature.

Beautiful Bow!
That's a lot of work to put into a ~35# bow. Were you intending for such a low draw weight?

Very nice,  and fast for a light bow. I done an Osage bow that is 34lbs and sinew backed. My first bow and not nearly as fast but nice to shoot. Patrick
