Pins springing back?

[Lesh18]

Hi all

Let's say I've been picking a lock fo 20 seconds, I am not being successful so I release tension and want to start again. Then, however, I hear three or four 'clicks', probably pins springing back. Does this mean all those clicks were overset pins?

I still can't seem to properly understand the concept of oversets and false sets.

Oversets: A top pin is above the shear with a bottom pin under it blocking the shear line?
What is a false set?
And what happens if a top pin is above the shear line (stuck up there somehow) but the bottom pin is free resting down? Is it just a normal set? Is this scenario even possible?

Because every time I pick, regardless of whether it's raking or SPPing, I mostly just give up and then I hear those clicks.

Thanks

Your description of over set is correct. Your description of driver (top) pins above the shear line and key pins is a normal set. A false set occurs with security pins when a groove is at the shear line, but the rest of the pin is both above and below the shear line. A false set feels similar to a normal set, but frequently allows more rotation of the plug before blocking rotation.

The clicks you hear are trapped or bound pins snapping back under spring pressure. They may be not set at all (just bound and held in place by the tension you are applying), normally set, or over set. Best thing to do is keep trying!

Good luck,

Those clicks are indeed pins springing back. But it doesn´t say they were all overset. You can get a click when: a bottom pin is binding from its bottom or its top, and when top pin is bindind from either end. And if you have some security pins there are even more possibilities.

You can find a lot of information from this site, use search and all your questions will be answered.

In short:
Overset - yes
False set - for example spool pin in wrong position turns the plug a little
If a top pin is above shear line and drive pin is free then it is a normal set pin. It shouldn´t get stuck anywhere above shear line.

Hearing voices is normal

Gordon you have quick fingers!

So what am i doing wrong that I hear those clicks? Am I applying too much tension? Or do I push the pins too hard?

All you need to do is read this Solomon´s great guide and also understand it. It takes time but pays the effort, password is evva3ks

You would think having grown up writing Finnish, you would have faster fingers, Zeepia.

if your pins are set properly and you release tension you will still hear the sound of pins snapping back into the default lock position, the driver (top) pin will slap across the gap into the keypin(bottom) when you release pressure. After i think i have a few pins set properly i hold tesion and roll the lock next to the ear i can hear well out of and count the very slight click as the keypin rattles from top to bottom of its chamber (because the spring is pressing on the driver pin which is trapped above the shearline). of course this can still result if the the stack is lifted and the driver is binding, but when im hearing multiple keypins rattling around in there i feel pretty confident i have a few pins set properly.

Does anyone else do this sound test?

Thanks for the plug zeepia
