[QUOTE="Honolulu Dick, post: 1027307, member: 24745"]Another thought has come to mind that may assist you towards developing your state coin project. At your local hardware store, ask for a package of J B Weld. This is a 2-part epoxy that comes in two smallish tubes, having a thick-bodied cream texture. Mix a small amount in equal proportions, and using a toothpick, dab what amounts to the size of a drop on the back of a practice coin. Press the coin firmly to another metal surface to spread the mixed epoxy. Let cure overnight and then try to pry the coin free. You will be amazed at the strength of the adhesion. Try making a hat pin using the same technique. Epoxy a small safety pin to a practice coin. This may call for more than a single drop - - - try using several drop size dabs. Press the pin into the epoxy and let cure overnight. Prepare the surfaces to be epoxied by cleaning them with a green scrubby, liquid dish detergent, rinse and thoroughly dry. Warm air from a hair dryer or a heat lamp speeds the curing process. For your first couple of experiments, overnight curing is recommended. Have been using J B Weld for decades to stick metal surfaces together when restoring antique horseless carriages. On critical surfaces where you can't use heat from a torch, it's one of the few affordable ways available for salvation. Have fun experimenting. Keep us informed of your progress.[/QUOTE]
