This set of plans will show you how to build the External Clock Lock Combination System along with 3 different styles of dials to choose from, each adding increasing complexity to the system. This locking system gets its name from the way the dials are used to enter the secret code into the lock. Each dial has 12 possible “stops”, just like a clock face. Once the code is entered, the knob on the right will release the lock securing the lid.
This is an indepth set
of instructions for the complete build of this locking sytem that works with a hinge type lid. This locking mecahnism is designed for the experienced woodworker and can be incorporated into any door, drawer or lid design.

CPB 2 is a ‘4 moves to open’ puzzle box. This box type has a lid that is hinged with a small recessed area inside the lid half of the space. This locking system can be put into any box that is as shallow and has similar characteristics. This locking mechanism I refer to as a “chase” lock since one
move needs to be completed before the next and so on. A simple mechanism that can be made just from the scraps found in your shop. A clever “starter” mechanism is introduced in this plan that requires the separation of two parts before the “chase” can happen. Easily built about an hour.
