Box with Locks came about because I wanted to design a simple key operated lock that would be simple to construct and be educational in the process. I also had a bit of fun adding in a couple of secret catches so that the finished box has some added mystery. This construction uses mainly standard joinery skills with a bit of CNC thrown in for the more detailed joint and lock parts. I always had trouble making neat box comb joints by hand so I devised this way of constructing them using CNC machined ends that fit with a half lap joint to the main panels. A single end piece with the box combed end machined in repeated 8 times takes the hard work out of the construction. I had a similar box that I made some years ago to store all my drawing kit, pencils , pens etc, but it could be used for collections of special items, or tools or even jewellery. I think it would have special appeal in delighting the children as they struggle to find the secret locks .
