Just wanted to show off my self-pinned practice lock set. I've got a set of progressive 2 through 6 pins and then 3 sets of security locks in mushroom, spool and serrated starting with 3 pins (2 standard 1 security) and going to 5 (3 std 2 sec) as well as a 6 pin with 2 of each security pin. All key pins are standard.
I've got enough cores here to make several of these kits... was contemplating making and selling them. I've also got an idea for a holder that you can slide the kik cylinders in so you can practice on the go.
