Rawhide backing
« on: November 07, 2013, 01:22:32 pm »
After messing with my rawhide test I was wondering if a rawhide  backing adds any reflex to a bow?

Short answer... no. Certainly nothing like sinew. Rawhide will protect a bow's back if any less than ideal tension issues exist... violated rings, knot, etc.

What adb said. I think thicker rawhide might offer some performance but its physical weight would negate that.

would it hold in reflex if the bow is reverse strung while the rawhide is applied and the glue dries?

That works for laminations. Only one way to find out.  I tried stringing a bow backwards and then just applying glue, no bacing or anything just glue it held 2" reflex until I shot it and it went back to straight.  But give it a try.  ;)

I've done rawhide backings glued up in reflex a few times.   I think it adds a little bit of performance vs. Gluing it on flat, but nowhere near what you get from sinew or wood backings.

It was either Nagler or Klopsteg in the 40s that took a rawhide backed bow and measured it, then took the backing off and measured it again. The draw weight went down, but the draw weight per mass of bow went up. Both differences were only slight of course, but still...

But for the sake of safety, rawhide is worth it I think.

No, its not very elastic at all. Its great for protection, but not performance.

If I recall correctly (always a question...), TBB mentions that rawhide can either pull a bow into mild reflex or hold it there.  I think they mentioned you needed to use real hide glue or some such thing to allow the contraction, as opposed to TB, as it functions a little differently and does not permit the contraction while drying as hide glue does. 

But, I could be way off.  Either way, it's a great backing material.
