Gluing Sinew

Kegan:
Okay, now I have to ask. Does sinew have to be applied with hide glue? From Yewarcher's last post, "56" of Osage..." I thought it was said that he applied his sinew with Titebond II, is that true or am I mistaken? If so then I don't have to wait and can start sinewing a new bow now :o! Is there anything different in the application with a wood glue?

D. Tiller:
Big debate ongoing about this. I think that Tightbond dries but does not shrink and contract like hide glue does. From what I understand Hide glue cantracts and shrinks at the same rate as the sinew does and pulls the bow into tension. Tightbond does not though and just holds the sinew on. Never done tightbond so I really dont know how it will work. Thats what I have heard though.

Guys when you apply the sinew do you soak the sinew in the glue and then aply it or do you put the glue on the bow and just aply the dry sinew to it?

Kegan:
Makes sense, but the Titebond does shrink, if only a little- where as hide glue shrinks dramatically. Hwich would then pull the sinew, which is stretching as it dries, tight. So it would make the sinew take on different backing characteristics... :P ;D This is giving me something to think about!

sonny:
there's no reason why you couldn't pull the bow into two to several inches of reflex as the sinew is applied and dries. you'll net a few inches of reflex whichever glue you end up using.

personally I don't foresee me ever using TB2 along with sinew but simply my preference to use hide glue. 

Kegan:
Thing is- when the sinew dries it would stretch, and the hide glue, with it's massive shrinkage, pulls this taught. The wood glue would simply pull a little bit and the bow would be loose... unless you put it into a relfex. Huh- that makes sense. I had just been thinking in terms of a straight bow.

Okay, thinking done, it's sinew time!
