I wasted a lot of time trying to heat straighten a bamboo backed Yew, the glue survived, but the bend returned after a week or so.
I ended up sawing it in half and making a take down.

what glue can resist the heat?

I used resintite, but I was careful to clamp thin slats to the side of the bow to keep the heat away from the glue line and was very careful with the heat. I wouldn't recommend it, I heat treat the wood before glue up if I want it heat treated.

Wooden Spring:
That's actually the biggest reason that I never use titebond 3. It is extremely heat sensitive. It never really dries hard, but stays somewhat flexible, and even in hot summer days, the heat and humidity is enough that it can cause separations. That's why I went to resorcinol. Never had a problem since - I haven't tried heat treating a resorcinol bow, but the glue is intended for industrial strength applications, so I can't help but think that it would fare better.

Pat B:
All TiteBond glues release at 150deg(F).    You can clean up the glue surfaces and re-glue the bow with a little reflex added.

mikekeswick:
Smooth on will resist over 100 deg. If cured properly.
