 Nope.  I trust hide glue's strength, but I would wonder about gap filling, drying time, and surface mating.

I have never done it but comon sense tells me it would work with all the caveats above and proper prep , it's been used in composite horn bows for thousands of years , Fish or fish bladder glues  claim to fame is longer open time ,I don't think there more moister proof , no proof of that tho , but have used the yellow croaker bladder glue & fish skin commercial glue ,both great glues , you would need a type with longer gel (open) time like those in order to get the boo on ,smooth on or urac would work much better with a heck of a lot less prep and technique !

Also, for anyone asking, I can’t find the yellow carpenter glue, and I doubt elmers school glue will work. Also, will ants eat the hide glue over time?

My point is; speculation is one thing, actual experience is another. How many of us have made a bamboo backed bow with hide glue. I haven't read about anybody doing this on the PA site but could be wrong.

If anyone has done such let us know how it came out and held up. I don't expect there to be many hands raised because we all chose a better glue. Boy, I wish the old Urac was still around.

Bamboo on wood no but wood on wood yes.  I haven't shot it in many years but the bow is still holding up

If a sinewed or laminated wood bow using hide glue is exposed to temps above 150 F or 50 C I would let it cool before stringing it up and shooting and that depends on how long it was expose to those temps too,but as to it's toughness for holding in normal enviornments I would trust it and do myself.

What different glues do carpenters and wood workers use for glue in your area? We might be able to help you make a choice.

And why is that Ed?  I find that once hide glue is dry it is one of the most heat resistant glues out there

The glues used around here are gorilla glue, mightybond, marine epoxy and latex glue. I’ve tried the marine epoxy and it seems too brittle. Laminated some thin bamboo together and broke when I tried to bend it. The bamboo bent fine beforehand.

If the hide glue has been cured fully yes.If under a year of curing I'd watch it.I should have mentioned that as part of my comment.

I don't know what temps you are talking about here but I heat-treated a sinew backed bow with no ill effects to the glue or sinew

The Turks repeatedly oven rejuvenated their flight bows.  Not sure what temp they used though.  You would still want it to cool before bending as high temps probably still put hide glue into the equivalent of the glass transition temp of epoxy.

Its interesting topic , I didnt know hide glue could take higher temps , good to know ! I know the turks reheated  tillering & hot boxed there flight bows but dont know what temps ! Ea-40 clamed it can resit up to 250 Deg F if cured that way for 2 hrs. I wouldnt want to try it.
