2015 as we carry on locking

As the year carries on, new projects, old problems and same physical security challenges.

One of the fields I have a passion for is redesigning the padlock and redesigning the Cylinder or Barrel.

I am going to try and focus on  the simplest but strong padlock latching point.
Secondly the way a key interacts with the barrel, springs and pins.

Any hint, viewpoint or suggestion most welcome.

Sketches also best way to explain or make a point.

Most barrels that are held by a spring usually need to pick the barrel to a certain position before the pin can be depressed.

When cutting a key from lock always leave the cuts slightly high then gently force the cylinder to turn in the barrel, take out key and check for marks on the blank or the pin then you fine tune the key Never file the pins or slides only the key blank is to be filled When fitting a lock makes sure that the latch and locking bolts are not visible from outside of the room. A gap between the door and the frame is the focal point of security. A big gap makes it easy to insert a craw bar and break the lock, this is the most common way intruders use to break through the lock bolts because the depth of locking latch is reduced
