I am not an Architect but rather just a homeowner. I am looking to build a hidden compartment behind a workbench. I travel a lot and have some handguns and shotguns that I do not want to leave in the open. I thought about building a workbench that pulls out to reveal a small opening where I can store these items. I thought it would be fun to incorporate a hidden lock/latch to open it. You know something using a book to open a room behind a bookcase. Things you read about in mystery books or in the movies. If someone has come across any resources, Net or books, I would appreciate any direction you may be able to provide.
