Flute with recorder-like fingering system.I milled this instrument out of wood in several pieces and glued them together. However the material should not matter so long as it is hard.The files lower.stl and upper.stl are for milling from 12mm thick wood on a Roland MDX-20. Attach the workpiece to a base piece of wood and mill lower.stl. lower.stl contains two holes to help position the wood when cutting upper.stl. Drill these holes deeper, flip the workpiece, then insert 6mm diameter wooden pegs. upper.stl will actually mill through into the base piece of wood, and it's possible to mill this with a ball mill bit, possibly producing a nicer finish than an square mill bit. (I am fairly new at all this.)Requires a cork stopper, 11.2mm diameter, 14mm length.To play, please to refer to the fingering chart. This is not a typical fife, it has more complicated fingering, very similar to a recorder. I play in the Society for Creative Anachronism, which has many recorder players, and this flute is designed to be able to play most recorder music.Source code to design wind instruments (see the make-instrument directory), very much a work in progress: https://code.launchpad.net/~paul-francis-harrison/+junk/design-instrumentPrevious version of the code, and notes from a talk on medieval and renaissance instruments: http://www.logarithmic.net/pfh/designTalk to me if you have a particular wind instrument you want to make, maybe I can come up with a design for you.
