With the new aluminum table installed and everything now flat and square, I wanted to take a shot at milling something a bit more complex for my overal CNC education and to see what the Shapeoko 2 can really do in regards to precision. The parts are for a Flat Nautical Whistle. There are several depths that must remain constant and accurate. The radius for the completed parts also need to matchup otherwise the whistle will not work. So the real test is, will the whistle produce 3 separate tones when assembled. Remarkably it worked, so well that I was asked to stop testing it! Please see the photos below.
