Question about non setting pins

[sublime progie]

I have a padlock All it says is hardened on the U part of it. It is Brass in color. I have only got this open once and i always run into the same problem. there is one pin that it seems no matter the torque and no matter how far i push it in it just springs back out. and i dont mean it drops down like the rest of the pins i can still feel the tension. any pointers or am i just too involved with the situation to see something extreamly obvious

Sounds like one of the other pins is false set. Test each pin you think is correctly set. If one or more tend to push the tension wrench back, the likelyhood is that you have a security pin.

a false set is just when you wedge the key pin in the sheer line right

and a safty pin is like a mushroom pin or the likes?

[digital_blue]

A pin stack can be false set high or false set low. Either the key pin is bound or the driver pin is bound. If the keypin stays stuck up (you can feel this once you get the hang of it) then it is false set high. If the keypin drops back down, but the driver pin has not passed the shear line it is false set low. This is harder to detect, but you'll get the hang of it. Apply gradually more pressure to the pin until it hits the shear line.

Safety pins hold diapers on. Security pins make picking more difficult.

It's the driver pin that is normally the security pin, however there are serrated key pins in some locks - predominantly padlocks.

Do a search on serrated & spool pins & mushroom pins. There's a sh*t-load of info on these and I'm not going to start typing again.

A safety pin hold up yer pants when the button pops off.
