The Safes Secretary’s Challenge

This Challenge was from Brian Leach. It was to make a safe, or some other secure box, such that no one, apart from the builder, can gain access to it. Brute force should not be used to get in to it! For example, members might have had a set of rods, strips or other parts that had to be moved so that the safe could be opened.

Whether there was anything worth having inside the box was another matter!
