Yeah, I see Terry's point, but I just put the hinges in as the last thing I do on a building session so they are cured in the AM. I just had a thought that I have not tried but should be even better. Get some of the Aero-Poxy like stuff, ya know, with the mixing nozzles, and squirt that in the hole. The nozzle tip will fit just fine and you don't have to mess with the hypo-needle. But be sure to use a non-thixotropic epoxy as you want it to sag so that it surrounds the hinge point. This is what I will do next time.
