The back is just a press fit at the moment, though a permanent mounting would probably use magnets. After playing it for a while there is not as much difference between the sound with the back on or off as I had expected. It may not be worthwhile making them with a back as it could get tedious getting the back on an off to tune it. Anyway here are a couple of mp3 files of a couple of polkas played with the back on and off. Recorded on a Zoom H2 about a foot away from the instrument at 192kbs and turned into 128kbs mp3s without any tweaking.

(Addendum: I thought the mp3 files might just play directly, but it seems as though they will need to be downloaded. If any of our esteemed moderators know how to make them stream, fee free to modify them)

Very very innovative. I love it when folks re-invent the wheel. And speaking of wheels, the square ones on my mule cart give a very bumpy ride... Would you have a look at them?
