Our customer presented us with this project. From her great-great-grandfather's farm (from about 1800) she wanted us to design a display case to be placed on her coffee table. It was to be so people could see the back (actually it was the from of the barn door) and see how the lock worked. When you look at the lock you will see the wooden pins that moved into the lock pin and are controlled by the lock key. Lois (Superior Acrylic --Riverside. CA.) and I felt the best method was to place a acrylic case over it and have a mirror on the back so that you could see everything. Lois made the case and holder for the lock and we built the base out of raw cedar. Because of the value (about $50.000) we did not want any support to be attached and the key was to be supported in the lock (this was done with a copper wire from behind the lock) so that the lock could be removed. You will see the hand-made nails that was used to attach it to the door.
