Master #140 Gutted

[piotr]

For those of you that are struggling with the Master #140 this may be interesting.

I cut open a recently bought Master lock #140 and the insides surprised me:



All of the driver pins are anti-pick. Specifically, three of the driver pins are spooled and one is (minimally) serrated:

Two of the three spool pins

The one serrated pin.

The Master #140 is no more a good introduction to spools! It was a good intro to spools when only one pin was a spool but now it has become rather nasty. I can't pick it (yet).

Nice pics, thanks... that pin setup is identical to abus, which is interestng.

Don't stress over that "serrated" pin. if abus are anything to go by, it should set just like a egular pin with no weird feedback whatsoever, so I wouldn't worry about it. Just go in, pick i like a normal lock until you drop into a false set and deal with it. Easy peasy when you get the hang of it

It's not the serated that gets me it's the three dumbells(These aren't spools, seriously they are dumbells)... I told you all this lock was evil and now I se why I don't feel so bad now.

Thanks for the pics and for saving me the trauma of gutting one of my favorite locks to find out what was inside.

Thank you so much, I've always wanted to cut mine open, but I didn't have any tools or a replacement lock. That's a beautiful look on the inside. I believe the one pin you called serrated is known as a barrel pin, please correct me if I'm wrong.

Pretty sure that serrated pin is just a standard driver with top and bottom serrations. The barrel pins that I have come across look more like with a slightly smaller diameter top and bottom of the pin.

Oh yes, you are correct, sorry about that. Thanks for the clear up.

No worries man

nice man, thats a great addition to the site, ive neer actually seen anyone take the time to do that... thanks

[xeo]

Cool. I've recently picked one of those and wanted to see the pins. Thanks for posting.

wow nice job like most my first security pin lock was master 140 glad to see one from the inside

Nice work man gives a clear insight.

Just a suggestion but this could be the start of something very big there are many padlocks especially that can not be disassembled

Obviously the cost of destroying a perfectly good padlock / lock cylinder comes in to it .

But on the plus side we on the site would end up with a data base of pin stacks within locks that can not be disassembled.

just a thought

catch ya lata have fun.....................................................

i have no qualms about destroying a lock to get at the guts..This way it helps us all understand whats going on....hats off to you piotr

Hm, I'll see what I can do sounds like a lovely idea.
