Massive black foundry mold, originally used to make a metal gear by making a sand casting with the wooden sprocket and then pouring in molten metal. This monster wheel has been retired and now makes a great piece of industrial wall art. It is large enough to use in a commercial space, or could make a statement piece for the right home. This was pretty easy to hang using a couple of metal brackets, but would also be very cool to hang it suspended from the center for a seamless look.
78" in diameter, roughly 20" deep.
