Locked Antique Safe

[Shieldr]

Sounds like some of your wheels are corroded in place. The drive cam and wheel #3 (in a three wheel lock) are free to move, but #1 and #2 are stuck. If your drive pins are 8.5 numbers wide, then that might explain why it's stopping 17 numbers away from your start point after a complete rotation.

What does it do when dialed CCW first, then CW?

Thank you, Shieldr for the reply.

When I turn the dial CCW first and then CW, the dial stops hard on the same numbers in the opposite order:

When I turn the dial CCW, it stops at 54. Then I turn the dial CW (passing 71 once and 54 once), and it stops on 71.

When I turn the dial CW, it stops at 71. Then I turn the dial CCW (passing 54 once and 71 once), and it stops on 54.

Please note: The stop is HARD on both numbers... something is banging into something. The dial itself doesn't feel stuck, slow, or corroded. I am hitting something that seems firmly in place.

Also, the dial bounces back in the opposite direction if I spin it hard.

Hope this helps solve the mystery.... thank you!
