Making a Recorder Instrument
After hearing news recently of the discovery of world’s oldest musical instrument – a 35,000 year old flute made from a wing bone – I wondered how it would be to create a “modern” recorder. Using example recorders at home, and with the help of the Internet, I began a creation in SketchUp. Here’s the procedure I used to make only one part of the recorder – the Head. The remaining parts include the Center and Foot pieces.
Step 1: I first created the shape of the recorder Head. I included space for the borings and the taper end which connects to the mid portion of the recorder, the Center piece.
Step 2: After placing the circular path, I executed the Follow Me command to complete the turning. The borings are included.
Here’s a look down the front end of the Head to show the borings.
Step 3: Next is the shaping of the lower section of the mouthpiece. I created a “cutter” with just the right shape.
Step 4: I positioned the cutter precisely in readiness for executing an Intersection.
Step 5: After intersecting, clean-up the waste material with the Eraser Tool.
Step 6: There is an insert into the front of the mouthpiece which provides a small air path into the Head.
The insert must have the same diameter as the boring, and also must be cut to the same profile as the mouthpiece.
Step 7: After executing Follow me, I place the mouthpiece cutter into position for an Intersection.
Step 8: Clean-up the intersection with the Erasure Tool. Also, to remove unnecessary lines, use the Soften/Smooth Edges feature. This can be found in a pop-up menu after selecting the surfaces and edges and right clicking on the object.
Step 9: With the Push/Pull Tool, make a small flat on the top surface of the Mouthpiece Insert. This provides a small air path into the Head. Line up the mouthpiece insert (I use the centerlines as guides for this).
Here is the Head complete with the Mouthpiece Insert.
Step 10: There is one more cut required – making the small slanted window opening in the top of the Head. I make a tool for cutting this window opening by determining and combining the horizontal and vertical shapes.
Step 11: After cleaning-up the waste after Intersecting, here is the resulting Window Cutter.
Step 12: Place the Window Cutter precisely and execute an Intersection. Before doing this, I find it useful to explode both the Head and Cutter components.
This was quite a project and only represents one-third of the total instrument. I can imagine how difficult this would be in the shop – someday.
