Questions about tension and pins being set or over set
Pretty new to lock picking... I have picked a bunch of locks.. the hardest one being Masterlock 140.. even though I still can't consistently get it open.
So just a couple questions that I can't seem to figure out or find the answer to:
1) When a cylinder has a sort of spring action to it (for example.. Masterlock 140) I'm confused as to what tension I use. Do I turn the keyhole until the spring stops, or still just use light tension? I hope this question makes sense. For example, on Masterlock 140.. if I use my tension wrench I can turn the keyhole a couple degrees against the spring.
2) I'm still having trouble finding the click of a pin when it's set. Some things I feel while using tension are:
--A lot of resistance... forcing the pin up gives me a sort of scraping feel. Is this the pin that is next to be set? (I know the scraping and resistance is probably from too much tension, right?)
--With the resistance pin, if I keep pushing on the pin it will eventually pop up.. then sometimes won't give any resistance anymore. Does this mean the pin is set, or does it mean the pin is OVER set?
--And sometimes I can push a pin up only a little way until it stops. Is THAT a set pin? It makes me feel like the top pin is above the shear line and the key pin is pushing up to the shear line, but can't go further because the cylinder is turned a little bit.
I guess I'm having trouble feeling if a pin is set or OVER set. How can I tell the difference? Sometimes it feels like all the pins are set, but the lock won't open.. when I release tension I hear the pins fall down. When a pin has NO spring left, and I can just push it up without resistance, is this pin set? Do set pins have any spring to them? Do OVER set pins have any spring to them?
Anyway I hope these questions make sense. I can usually pick most simple non-security locks, but the masterlock 140 is still giving me trouble. Not sure if it's the spool pin or what. I just got a bunch of security pins in the mail today so I will practice with those and hopefully gain a better understanding.
Thanks guys!
