I found this design online and though that it was an incredible repourpose of a piano that apparently is no longer usable. I could also see this made into a dining room hutch and buffet style piece of furniture. Nice to see something so grand used in a different way.
Thoroughly clean can and dry — Paint or decoupage the outside of can with a unique design — Seal with polyurethane — You will need a (minimum size of) 18 inch galvanized bolt (about 2.50 at a hardware store) with a washer and nut. Puncture hole in bottom of can and push the bolt through from the inside of can until head in at the bottom. Under the can on the bolt add a washer and then secure the nut tightly. The longer bolt you use the better. You can also polyurethane the entire can, nut, washer and bolt once done to give a nice shiny presentation and to help prevent rust.
