An update on my quest to streamline reloading 126 cartridges for my Kodak 500 Instamatic. I've discovered that foamcor is not dimensionally stable so after a bit of time(days) the jig has warped a bit. I think the next version should be something more stable. Perhaps Plexiglas? I'll need to make a jig for my table saw to make the next jig if I go that route. Anyway, this is what the jig looks like now. Rather crude but you get the idea. I spread the perfs out a bit b/c I like more room between exposures. The advance stroke is now one and a tiny bit. BTW the kodak does not make a square neg, it's actually 28mm x 32mm.
