Glue it better next time? (A) ;D
Sorry about that, couldn't help myself. My only answer would be to re-glue it with a more careful prep the next time, but I doubt you did a bad job of that the first time around. What did you use for glue?
Your fades are pretty steep but most of that is on the glued on portion and the main bow body thickness transitions pretty smoothly from the limb thickness to the glue plane, which is where it really matters. The bow body thickness under the glued on handle also looks to be enough that the glue joint shouldn't be really heavily loaded. Maybe try smoothing the fades on the glued on handle a bit to ease that transition some more?
Just an FYI, for those that like to groove up or coarsely sand their lams and other gluing surfaces, Smooth On recommends prepping surfaces with 120 grit paper for use with EA-40 and there is research saying that a freshly planed surface is significantly better than any sort of abrasive prepped surface for bond strength. Despite what people think, glue bonds at the microscopic, cellular level in woods so what it sees as a rough surface and what we feel with our fingers are two different things. The only thing a rough surface seems to offer is voids in the glue line that might be good for avoiding glue starvation in the joint, similar to how fumed silica works to prevent the joint from closing tight.

Will this work?
Badger:
I never go over about 64" long with a glue-on handle if the handle section is 3/4 thick. Not sure if the liquid weld is any stronger than tight bond, I know some of the epoxies are stronger.

Only thing I can tell you is the longer the set time, the stronger the epoxy.

If the bow is your usual 69" or even 68"... and it was only 64"... it would have to trim some weight off. So, let me know how much shipping is...send it to me...and make a shorter bow. :OK (lol)
