Tuba Helleberg Mouthpiece (trial)

See https://docs.google.com/spreadsheet/ccc?key=0Aj4tonrQxb3fdHl4ZGJrWF9KZE5qcnEyM0w3SDA0WGc&usp=sharing for more numbers. I'm taking measurements of my mouthpieces with calipers. I don't really like how long the cup is relative to the back pipe; I don't think the parameters work particularly well for tuba mouthpieces, but we'll see. Update: turns out that the cup depth is the inner depth, and I measured the outer depth. I'm going to get some modelling clay to see if I can take a mold of the inside, then I should be able to directly measure the cup depth and the throat diameter.
