I am going to make some boxes this weekend for my mother to give as X-mas gifts. They will be heart shaped with a heart shaped locking key piece. I want the lid to pivot on the point of the heart. I plan to use some sort of a pivot pin, but the more that I think about the design, the more I think I may have a problem. In order to remove the locking key you have to turn the box upside down, using a pivot pin epoxied into either the lid or the box would allow the lid to potentially fall off when the box is turned upside down. So on to my inquiry...Is there any sort of pivot assembly that turns within itself and could be epoxied into both the box and lid. I checked Woodcraft on-line and didn't see anything, I could order them if I could find them, but I don't know if I am hunting for something that doesn't exist. Any thoughts or experience along these lines? Thanks in advance, Dave
