Sounds like what we call CA hinges that were developed to use thin CA glue to hold them in place. Actually that is what comes in the kit, at least that what was in my kit. I opt not to use the kit supplied hinges but used a different brand of CA hinge that i have had great success with. If you used wood glue such as Titebond to glue them in, i would be a bit worried too. I would suggest you do a test on a couple of pieces of scrap wood, glue in a hinge, let it dry and check how well it holds when you try to pull them apart.
