  1. Correction:
    In step 3 if the remainder is 2 or 3 subtract 2 (resulting in 0 or 1).

    Hint:
    My g/f Atira points out that if you’ve been out of high school awhile you have forgotten the basics of a master lock. So:

      Clockwise a couple times to reset
      Clockwise to the first number
      Counter-Clockwise past the first number to the second number.
      Clockwise directly to the third.
      Yank hard.

    Thank god I’m dating a younger woman, I’d have never remembered that on my own.

  2. That’s not a Master Lock- its an American brand lock.

    I’m not usually such an ass about stuff like that, but I don’t know if it would work right on a masterlock.

    Very cool, though.
