I'm new to bow biulding and trying to find an epoxy that don't require a heat box for laminated recurve I've heard of g2 but can't find it for sale anywhere pleas help

Smooth-on epoxy does not need a hotbox, just cures a little better and a good amount faster with one.  It's fine at room temp though, just give it 24 hours.

Titebond 3 is fine at room temperature as well for all wood bows.

I use Unibond for my laminated wood bows.  Just needs to cure at 70 degrees minimum.  I've used TB 3 for glueing handles and cherry bark backing on and it bonds great as well.

I like g2 as it can be cured without a hotbox and has good compressive and tensile strength. You can fiind it at Lee Valley tools.   www.leevalley.com   They occasionally have free shipping on orders over $40 canadian.

If you're building a wood-glass composite bow then Smooth-On is the glue of choice.  It works just fine as long as the temperature stays above 70F, but takes 24 hours to cure rather than 4-6 hrs.  

As Mike sez, for wood-wood composite bows it's hard to beat Titebond II or III.

One caveat with TB 111 - you must have perfect mating surfaces. I use 80 grit paper on a drum sander to prepare lams.

Is this G2 suitable for glass bows? Bue--.

Bue, I havent tried g2 on glass. I have only worked with it on wood and silk. It does mention on the website that it can be used for bonding wood to fg.
