Was cleaning up the office and came across these shots from several years back - a Chromatic Bass Marimba I built for a school in Federal Way, WA. These are a blast to play, makes you want to join a band. A real handful to set up and transport, with lots of odd parts to fit together!
Note the angled bass tubes, otherwise this unit would be 6 feet tall.
..... not sure the angle cut on the tubes for the sharps and flats was necessary, but it looks cool.
