Dudley Combination Locks

[Massif]

Nope, those are both pretty far off except the 22. The position of that one is off as well.

[rayman452]

whats the combo?

[Massif]

it is 20-0-30

Kind of an odd one since it includes 0....

[SCREAMinBLUE]

I have a Dudley (black dial) that's been sitting in a drawer. No one knows the combo. If you can explain how I get the sticking points exactly I'll post them here. I get the concept but do I start in a certain place and turn which way?

thanks

For everyone else who posted sticking numbers, can you repost them with the colour of the dial?

I don't see why you couldn't just scroll back through the thread, but ok.

Here's my sticking points:

0.5-3.5
6.5-9.5
12.5-15.5
18.5-21.5
24-28
30-34
36.5-39.5
42.5-45.5
48-51.5
54.5-57.5

The dial is blue.

For your excel graph for Massif's lock, did you just plot the sticking points of your lock and Massif's and then superimpose them by sliding one across to the other?

[rayman452]

I had to, since he had a old lock with a number as 0. That really messed my chart up, so if you have an old dudley, I may not be able to crack it as well... Blue dials are a little harder, gotta get my friends combo then, should have it done though...

57.5 - 0.5
3.5 - 6.5
9.5 - 12.5
15.5 - 17.5
21.5 - 24.5
27.5 - 30.0
33.0 - 36.5
39.0 - 43.0
45.5 - 47.5
51.5 - 54.5

I'll jump back into this again, it almost looked like it died for a day or so.

Easy enough, just put the dial at 0, and pull up on the bar as far as it will go. The dial will be able to jiggle around, usually for 2-3 digits, or a decimal. Depending on how old the lock is, there may be some wear and tear, so it can move a bit further than usual. The limits of where it can move when the bar is pulled up are the sticking points. Usually, they are between 3-5 digits apart, maybe a bit less or more.

I'm going to try looking for any difference in the false indents vs. the real one in movement distance, the distance that the bar can move, etc. There's got to be something....

[rayman452]

yea, for everyone who has a sticking point that passes through 0, thats a false reading. Be carful, theres one inbetween 0-6ish, and another 55-59ish. Find those sticking points and post again please, cuz if theres a 0, its either a really old lock, or you did it wrong. Thx...

[rayman452]

orange, can you pm me your email so I can work on this with you differently, like more messages between me and you? And that other guy who was gonna get us pictures...please hurry...

Hey guys,
just stumbled across this place, i found an old dudley but don't have the combo for it. I'll put the sticking points up soon. I'm still a little confused by your graph, rayman. Why is it that you have 2 of them (your excel graphs i mean)? And how do you plot a sticking point as a single number? Are you taking the middle number from it?

I guess I haven't really contributed much to your cause, but i'd like to help out however i can.

One last question: are you just assuming that all dudley locks are related in such a way that your graph will work or is there some background to your reasoning? I don't mean to sound skeptical, but I was under the impression that the locks aren't related.

Hey y’all. It’s been a while since my last post, I’ve been working long hours and haven’t really had much time lately. I see this topic is pretty popular, closing in on 2000 views.

Anyways, both of my locks were blue dials. Here are the middle numbers of my sticking points again. The first one I know the combo, the second one is one that my friend gave to me and we’re not quite sure of the combo. See if you can crack them.

3-4
10-11
15-16
22-23
27-28
33-34
40-41
45-46
52-53
57-58

4-5
10-11
16-17
22-23
28-29
34-35
40-41
46-47
52-53
58-59

B.t.w. rayman452, good job with the graphs and all. I’m likin’ your idea of how all Dudley locks are designed with the same notches. I can see how that would work. Hopefully you’re right with that theory.

[I'm Just One]

I almost forgot..

Orange_Crusader, I was thinking something along the same lines as you about the distance the bar moves. It would be cool if one could measure such a difference in the distance but I'm pretty sure that it would be hard to do so accurately. Though it sure does feel like sometimes the bar has a little more give than other times...[/quote]

[Orange_Crusader]

Well, it wouldn't be too hard. Just put the lock in a vice (dial facing up), with a piece of paper or ruler, or something behind it to measure the distance. Better yet, just tape a strip of paper to the back of the lock, making it long enough to extend up past the bar a small amount, and notch down where the bar comes to, and see if there is any difference. Try it with different parts of the combo, such as just spinning the dial and checking, doing the 2x clockwise turn, then to the first number, try and notice a difference. Or, put in the first 2 numbers, and try to see a difference on the 2nd one (since pulling on the bar mid-combo resets it). If there's a difference, it will most likely give you the last number (since the dial techincally is only attached to the last disk. But, if you get the last number, it makes a lot easier to get the 2 others (assuming the 1st#>2nd#, and 3rd#>2nd#, and 1st#<3rd# (this one is for most locks, I think) "rules" are accurate. Worth a shot, I'd say.

Hi. I stumbled across this thread off of Google. I'm very intruiged and want to help. I just don't understand how you determine the combo and order from the notches. I saw those graphs, but I didn't understand how they were made and compared.
