Ted Bau, a 4 hour project snuck in while waiting for finish to dry on the real work today. I used a stew can and a tuna can, both sprayed gold. The base is a 2X4, the trem thing is a dowel sprayed black. The base for the big can as well as the mount support inside it is wood that's sprayed gold.
I added a piezo inside the big can sandwiched between a piece of rosewood with foam double stick tape and the can and screwed into the mount for the tuner on the outside.
Man this thing is fun to play!
