Have you ever noticed that certain objects multiply if left in dark places? Wire hangers, bills and keys come readily to mind. I'd been playing with a way to make a sunburst mirror when I stumbled upon this box of keys. A new project was born!
wooden circle (this one is 6")
old keys (about 40 for this size)
round mirror (this one is 4")
brass screws (20 flat head and 20 domed)
small drill bit
Lay keys around the perimeter of the wooden circle, allowing the notched areas to overhang the edge. Drill holes into the wood at the key openings that are a bit smaller than the diameters of the screws. Use the flat headed screws to attach the keys.
Glue the mirror in the center.
Surround the mirror with the rest of the keys with the tops overlapping the mirror's edge, offsetting this row. Drill holes as before but use the domed screws for this layer.
I used slotted screws instead of phillip's head for an older look.
The domed screws give a more finished look, but use the flat heads on the first layer so that the top layer lays properly.
Predrill all holes as brass screws are soft and the slots tend to bend if you force them with the screwdriver.
Check your junk drawer and ask friends. I'm sure you can come up with 40 keys in no time.
