Corbin with weird pins

[Pickermeapie]

Oye!, digital_blue, I was refering to the idea that if each pin stack had a master pin in it, depending on how many stacks have master pins, you could have -several- points at which each stack will set at the shear line to allow the plug to turn. For instance, if you had a 6 pin cylinder, containing 5 master pinned stacks, you could have, what 32?, 32 keys that could work for that lock. I have no idea what you are talking when you say 2 Shear lines, because I dont think its what I am refering to above.

If you took all the pins out of that cylinder, there is a piece that looks like annother "mini" cylinder. That is the pare creating the two shearlines in this lock. It functions like a plug (without a keyway) some pins will fall into the plug or be raised into the master ring letting this ring and plug turn, or the plug just turns.

I have no idea what you are reffering to. "Mini-cylinder"? Mind you, im not mocking you or refering to what you said in a deragatory sense, i just dont understand what you said! Clarify a little better if you can, please

The Corbin Master Ring system works on a concept very similar to the control lug in SFIC. There is a ring about the cylinder. Your key can either turn the cylinder, or the ring and cylinder together, allowing for very large master key systems.

Yes, this is what I was driving at. I think mikeg was correct when he said:

These cyllinders have two shear lines in them.

I was just confused by your statement:

Yes, thank you for establishing that MikeG And for the record, im sure this has more than 2 shear lines in it. It can have multiple depending on how many pinstacks contain master wafers.

No offence at all taken. I was just trying to clarify this issue. Cheers!

Pickermeapie, it's a matter of using the correct word so others will understand what is meant. "Shear line", by convention, refers to the interface between the plug and the shell where the plug can turn. Regular locks have one shear line, and some special kinds of lock like the Corbin in this thread can have two shear lines.

The breaks in the pin stacks, although they do shear when the lock is turned, are not generally referred to as shear lines. So saying that a lock has "many shear lines" is not correct use of terminology and may confuse other people, as happened here. The correct thing to say is that there are several key bittings or pin settings that can operate the lock.

Hope this clarifies things.

Yes, masterkeyed locks have the possibility of numerous keys. let us say that a pin column has two different breaks, call the top break 1 and the bottom break 0 regardless of the actual pin depths. if this is done in all five places, it will open to 11111 11110 11100 11000 10000 00000 11101 11011 10111 01111 11010 10101 01010 10011 11001 00101 etc. well there are quite a number of possibilites, but a corbin ring cylinder eliminates this because the lower breaks have an entire shearline to themselves, and the upper breaks have one of their own. the pins do not reach the other shearline. The corbin ring cylinder is not common in hotels anymore. I don't think they have been made for many years. The modern cheap masterkeying with all the key possibilities has taken over.
