Dudley Combination Locks

Note that I am one of us Canadian folks.

My dial caliper is most acurate in 1000ths of an inch. If you are interested in bypassing these, use a shim. Why reinvent the wheel?

The dudley is designed not to open with a shim. Look at the parst you have... There has got to be a design flaw somewhere in the dudley. Nothing is impossible...

where are those thermite lances?

by **digital_blue** » 22 Mar 2005 16:38

Nope. I'm afraid it's a fortress, impervious to all methods of bypass. Why the government hasn't picked these up to protect the missle silos I have no idea.

rayman, I converted all of digital_blue's measurements into millimeters for you if you still need them.

Third wheel (with all the false gates):
Outside diameter to outside of false gates: 20.63mm
Outside diameter to inside of false gates: 18.95mm
Measurement from notch to notch on false gates: 5.0mm (same for true gate)

Other 2 wheels:
Outside diameter: 19.36mm

Ok, then I think Im onto a slight flaw. Orange, correct me if Im wrong, but, you also knowtice that some spots stick more then others. Now, if all the gates are the exact same, then that shouldnt happen. What may happen with those that stick more is that like impressioning, the shackle is actually scratching the gate, making it stick. Therefore, the one that sticks the least has a high probibility of being one of the correct numbers.

Seems right to me. I'll look over my available locks for any differences in the "feel" through the dial in the gates, checking for smoothness, how far it moves (or can move) off of a whole number (say, 21.2 rather than just 21), and whether or not the dial tends to try moving up or down (locking piece, with med. pressure, might start to slide up one of the notches, due to the eventual wear and tear on the lock, and the locking piece scraping by it (a typical high school lock is never opened with precision, and the notches are bound to have some wear and tear. I've noticed that all the locks I own have a combo that uses the general 1st<2nd, 2nd>3rd, and 1st<3rd<2nd, so that narrows down the possible combos, if the last # can be obtained.

What do you mean by sticking less? If the shackle is held with light pressure, and the dial spun, then are you saying that the one that offers the least resistance could be one of the numbers? Sounds right to me, as long as the other disks don't get in the way (which apparently, since we can clearly measure and not the sticking points, they don't.

d_b, I can see where you're coming from, seeing as they are very hard locks to crack (no shims, no sounds when right # is hit), and several other people have tried and not gotten very far with these. Still, it's not impossible, like rayman said, if there's a will, there's a way. Maybe it's because no one else has done this before (to this extent, I haven't found anyone who has done this much on this specific type of lock) is why we're doing this. These lock aren't perfect, and CAN (eventually) be cracked, and it's our LP101 duty to do so. The "wheel" for Dudley's hasn't been invented yet, it'll just take another idea and a lot of work (comparably, other locks, except the toughest, can take seconds to hours to crack, padlocks with shims, and taking apart a regular lock eaily reveals how to crack it) to come up with a new wheel. We're not re-inventing it, we're inventing it plain and simple (for Dudleys, and as far as I know, correcr me if I'm wrong). Don't worry, you'll know when these are cracked, it'll be annonced and celebrate with much fanfare, congradulations, and cake.

Gents, I have TWO identical Dudley's for which I've forgotten the combo. They were bought as a set at least 5 years ago from a Staples/Business Depot. Two locks, one combo, less chance of forgetting, but I still beat the odds.

Can anyone help me crack them??

The sticking points are the same for both:

58-01
04-07
10-13
16-19
22-25
28-31
34-37
40-43
46-69
52-55

They are both silver with black knobs, and have a "B" engraved on the back. I wouldn't want to swear to this, but I think I recall "52" being either the first or last number, but don't let that throw you off.

Cheers,

Werowance in Ottawa

69 in your lock? 46-69 ?

Anyways, I got an email from someone asking to crack it, so Ill probally do that on mny spare time tomorow. WEll see then

by **Orange_Crusader** » 27 Mar 2005 20:34

49, simple mistake. d_b, the sticking points might have something to do with the combos yet, seeing as the same combo has the same points.

Odd how your points cross over 0, while most I've seen don't. Your locks fit into the patterns (using 3,4, and 5, your being 3,3,3). We'll have to wait and see what rayman gets with the points. It might not be perfect, within 3 or so digits, and the numbers might be in the wrong order (backwards, I believe), but they should be there if the chart works well. I'll still see if any cut or broken locks are at the janitors on Tuesday, otherwise I'll get them to cut me a lock from one that's been locked to a stairwell railing or vent grate (plenty of those, sadly :roll:

). Best of luck to all with this. We need a thumbs-up smiley...

by **werowance** » 28 Mar 2005 5:35

Yes, a typo. 49, not 69. And that first point, 58-01 does indeed cross zero. I tried it multiple times on both locks. Thank you for trying, I look forward to testing the chart results.

by **rayman452** » 28 Mar 2005 11:11

This is starting to sound like were trying to find if he has cancer or something. Ill get to doiung the charts now...

by **rayman452** » 28 Mar 2005 11:31

Ok, I just did Sabin's lock right now, and Im not 100% sure I got this perfect. I think we have to open our mind for even more possibility, though I narrowed it down to 4 probable numbers. Ill continue posting it untill I seem to crack it. But for all those people who wanted to have them cracked, please copy and paste them over again, telling me what colour the dial is, double check that the sticking points are exact same with the decimals where acceptable, and give me 2 sets of them. That means 10 sticking points for going clockwise, and 10 sticking points for going counter clockwise. I think thats why we havent been able to crack them yet, were only looking at one side of the scale.

20-25

those are the sticky points, dial and numbers are vlue NO animation on front of it, and um hopefully i can be of help to u guys, also, i will have another lock hopefully soon with sticky points and combo, etc, thanks for n e and all help

Zodic, just looking at those sticking points, without my graph since you didnt post the reverse like Im asking now, Im guessing the combo is somewehre along the lines of 23.5ish, play around with that, 39, and 52. Keep in mind that thats not in the right order, so the right order would be...dang, forgot the rule...umm...39-23.5ish, 52 maybe maybe. If not, just try rearranging them, you only have 9 to try, chances are the one I posted followed that rule or something. Try it.

by **Zodiac** » 28 Mar 2005 12:16

um i m not sure how you got that there would be 9 possibiliteis i only found 6 differnet possibilities, and none of them actualyl worked....but i think the 23.5 is close to the correct number... thnaks for trying, hopefully you will be able to et back to me about the nine combinations[/quote]
