Title: Heat and Glue?
Post by: DLH on March 14, 2011, 05:32:00 PM

Does heat treating cause all types of glue joints to delaminate like TBII will? Like could you heat treat a bow with URAC used to glue it up?

I know of a few guys that have has some luck heat treating backed bows with Urac as the glue but IMO it is taking a big chance.

Urac is excellent using heat, and using smooth on epoxy most commonly used in building glass bows, heat is not necessary but it is recommended for the curing process.

In my experience once epoxy has cured, extreme heat will make it harder and more brittle once it cools. if a bow is cured at 180 degrees it's not recommended to exceed that temp again.

One very inportant thing people often miss is to preheat the lamb parts.Glass and wood skins in limbs or riser lams.Anything to be glued.Whatthe preheat does is open the pores in the wood and allows the glue to soak in.This will give the cured baking a much better solid hold.I agree with Kirkll,avoid the finished glued items to ever get to the 180 degrees.
