not sure where I haave seen it - maybe on paleo planet - but I think Tim Baker made some experiments building up a bow's belly from hideglue....! dunno how it came  out tough - maybe ask him.
cheers

I have done experiments with this using my own hair. I've grown my hair down to my waist line several times and cut it off for this very purpose. I used hide glue to secure hair to one bow limb that had a hinge in it. The hair worked to stiffen the hinge, and made the limb as a whole stronger than the other limb. The problem I encountered was that hair is slick and glue does not hold it very well. I'm going to try some acid to see if I can etch the hair sheath so the glue bonds better. Then there is the issue of air bubbles, it's a solvable problem, but a problem no less.

Point is, yes, it will work. But my gosh what a pain in the a. I'm this far into it, I'm going to finish the project, then never do it again.

sweet! So someone has tried it! and yeah I was thinking maybe even dunking the hair into a lye solution to pull all of the oils off from the hair. Maybe even a wood ash solution to keep it in the primitive realm. Also I suppose with the bubbles you could try the torch technique. Heat the glue up with a torch or heat gun and the glue liquifies more and then the bubbles float to the surface and pop...Was there a problem with the glue buckling/ cracking at all?

Del the Cat you can push a piece of string if there is something supporting it from side to side like a tube. The glue acts like a tube in a way, a tube that forms perfectly around the hair.
