Title: Wood glue as a backing?
Post by: eastcreekarchery on November 09, 2020, 09:00:40 am
What do yall think about a few layers of wood glue painted on the back of a bow as a backing material? I think it would only provide protection like rawhide and its not veryyyyy traditional but do you think it would work?

It wouldn't be as strong as rawhide. I've seen bows sealed with wood glue but never seen it used as a backing. Add brown grocery bag paper and you'll get a little more protection.

Wood glue doesn't have a structure that would provide any protection for a bow's back. Almost anything would be better.

OP, you can use a light fabric with wood glue to back a bow for safety (I used an old bed sheet for a couple) but the wood glue is useless on its own.

I have used AD-40 Smooth On with backings, and it always gave me a better sense of security in he long run, but that may be only in my head though epoxy is stronger than wood glue.

The trouble with backings is that you never really know if they did anything or not. Was it really going to break or did you just think it would? it's a judgement call on your part.

DC,, I agree,, but when I started,,  I read Jay Massey and Pope and Young both expressed the opinion that backings had reduced failure in their bow making,, so I figure it couldnt hurt,,and took their experience or opinion to heart,,

Rawhide, linen, silk and burlap (in that order) can be put on with Titebond 3 and add protection.  Jawge

I had a rawhide backed osage longbow, "Shere Kahn", that had over 1000 arrows shot through it and one night me and Evan Williams had a discussion about using back muscles at the end of my draw to increase my draw length by 2 inches. When I tried a demonstration poor "Shere Kahn" became a takedown bow, in a dozen or so pieces. It was quite the explosion but my point is a backing won't keep a bow from blowing and in my case it didn't help stupid.  (--)
 I'd say these backings are more of an insurance policy for you, to give you a little more confidence in your bow. Any time I'm not sure of a bows back I will put a rawhide backing on it.

I got a kick out of your story Pat B.  I have had self bows explode into several pieces. Wild Choke Cherry comes to mind. With backed bows it seems like it slowed the process down for me.You hear a crack ,and when you stop ,and look  you see the crack coming through the backing. Never had a backed bow explode like some of the self bows.

Also rawhide can vary quite a bit in strength depending on how it was treated to make it into rawhide.     I made some good stuff many years ago and backed a HHB bow which I later deliberately tried to break by overdrawing.  I could not do it.  The string would just slip off the tips.
