I needed a large visible clock for my garage. With a limited size laser cutter I came up with this idea. It is 20" in diameter. Easy to make and set up. Can use pins or brads to attach to wall. I used push pins. Made a mount to easily attach the clock. This makes the clock easy to move or relocate. This same idea can be made even larger. It has 3.5" hour discs. Different shapes can be used as well. The clock works is a large hands high torque model from Hobby Lobby.
