Epoxy or Poly for pinned hinges, I prefer epoxy. I use the grease method described by FHHubber to help prevent the hinge joint from being glued... works well. The hardest parts with pinned hinges are alignment and getting the epoxy in. There are tools available for alignment, for both the slot type and round (robart) pinned hinges. As for getting the expoy in the slot/hole, I use a syringe to squirt the stuff in, which seems to work well. You can find large syringes at various places, I typically find mine in the wallpaper section of a paint store. Just ask for wallpaper repair syringes. Ditch the needle and just shoot the epoxy out the end of the plastic orifice. You may need to increase the diameter of the orafice for better flow, just drill it out some. After, if you expel all the epoxy and clean with alcohol, you can reuse the syringe about 10 times before they buy the farm.
