Re: Field & Stream gun safe (by Stack-on) direct entry
OK, so my theory checks out after changing the combination on this one. The other safe at work will be my verification... here's how it goes:
1) pick any gate on w3
2) find any gates on w2 and w1 (took less than 30 seconds on this one)
3) feel w3 gates for grindy/free-wiggle, free-wiggle is true gate
4) Now, we're going to take that w3 number and make a list of 13 numbers (one will be the same hole and excluded, one is an imaginary hole in the middle of the gate but needs to be included because we don't know where the gate is on the wheels yet). The formula is simple: for w2 subtract 1 from w3#, that's your base, then add/subtract 7.69 repeatedly until you come around to the starting point. For w1 it's the same except you subtract 2 from your w3 number. How'd I get 7.69? 100 increments divided by 13. With the easy tolerances of these locks, we could round to hole numbers for our list and still hit what we need, but for this example I'll keep it strict...
So in my case my w3 is at 42.
w2 will be on one of these: 2.55, 10.24, 17.93, 25.62, 33.31, 41, 48.69, 56.38, 64.07, 71.76, 79.45, 87.14, 94.83 (can't be 41 because w3 pin is there)
Park w1 on the gate we found in step 2 and check these numbers for gates on w2... I had gates at 9, 12, 22, 38, 47, 58, 72, and 81, so I actually have only one match at 72 (and that was my number)
w1 will be on one of these: 1.55, 9.24, 16.93, 24.62, 32.31,40, 47.69, 55.38, 63.07, 70.76, 78.45, 86.14, 93.83 (71 is the same pin hole as previous 72, so excluded 70.76)
park 2&3 on their known gates and check these until it opens. We could compare gates here if we had more than one gate match on w2, record our matches and end up having to try a few combinations to get the right ones, but I'm guessing it'll never end up being more than 3 matches on a wheel. But since we only had 1 match on w2, when we find our gate here we're open. In this case w1 was at 25.
5) Cold beer.
I'm betting I can get into that other safe at work in less than 15 minutes...
Thoughts?
