I found the box in the garbage while walking the dog yesterday and I knew I had to make a fiddle. It looks like it was a chunk cut out of a cheap veneer door or something. This was my most ambitious instrument-a-day, coming in at 6 hours.
The bridge is cut from poplar, the strings are nylon guitar strings, the bass bar and sound post are garbage wood, and the neck/fingerboard is, of course, a rotten stick. This fiddle actually leaves mildew on your left hand when you play it.
The bow I made yesterday literally disintegrated overnight – the screws unscrewed themselves and the hairs fell out! So I played the fiddle with a rosin-coated popsicle stick. Bear in mind that (1) this is a horrible, horrible fiddle and (2) i have no idea how to play a fiddle, before you listen to the sound sample.
