Ok, here’s the first real prototype of the edge-trimmer, which is a little more solidly constructed than the chair leg version… It currently isn’t hooked up to make any noise, although it has been tested with an unmodulated damping force. It’s pretty heavy, so it looks like it may have to be used in a similar manner as a cello and rest on the ground or a convenient table. As it doesn’t have a built in resonance chamber, a table would be useful in amplifying the sound produced.
