Pin diameter and position of stacks relative to shear line

Postby cyclops1101 » 9 Jan 2007 9:14

Hi,
Just wondering if anybody knows the best way to to get the above information.
I presume the pin Diameter can be felt by the binding pin(indicating the fattest pin, therefore the widest)
but how does one feel the position inbetween the pins(shear) and location within the plug/cylinder without looking at the key biting or feeling the set key pins. How can one feel the size of the pins i.e high-low-low-high etc???
Can this be done?? (Technically Im a noob)

Love to hear all skills and techniques aswell as methods

pin diameter shouldn't be different in a lock.... there are some pin charts (spacing depth ect...) around....

other wise I'm assuming that you are talking about doing this whilst picking the lock?
o when taking thelock apart

I thought this was what created the binding defect, not forgetting the axis alignment. i.e When tension is applied to the plug the fattest pin halts rotation(or first pin stack in rotational axis). This was what is writtain in 'The complete guide to lockpicking' by 'Eddie the Wire'
Is this incorrect?

there are some pin charts (spacing depth ect...) around

Ive tried searching but cannot find any links. Could somebody provde one for me?

When picking the lock, yes.
Is there a way to feel how close the pin stack shear is to the shear line?

the diameter of the pins for a particular lock should be the same (with in reason and obvious not perfect but with in nanometers)

heres a D&S Chart

took some time to find that let me tell you

Thanks for taking the time. What is it that you found? Is it a screenshot of a visual basic program?

So the binding defect is created more by the position of the pin holes rather than the diameter of the pins?

Wow. That some wicked info. Ta

So concerning the binding defect, The pin diameter plays an important roll in bypass? Does it not?
And when picking the binding pin is it possible to feel where the shear line is within the pin stack? i.e to avoid oversetting

Yes. The pin feels like it hits a wall and the cylinder shifts very slightly. The magnitude of all of that depends on the tolerances of the lock, as you would expect.
I'd go and read the MIT guide, it has little graphs that show pin response to pressure. Those engineering students :-)
