Wondering if anyone has a good suggestion for an air pump for tuning and playing with reeds? I saw an earlier discussion that more-or-less concluded that an old bellows was the way to go. Probably OK for tuning, but I also want to do some experiments with reeds, and a constant-flow, hands-and-feet-free system would be preferable. Ideally quiet so as not to interfere unduly with measurements and recordings. Desirable to have suck and blow available. Don't want to spend a fortune though. Any bright ideas? Good to know too what people have tried and how well they have gone. Nice to kno
You may remember me talking about getting some bits together to research concertina pneumatic issues. Well, the slow boat from China has come in, and the even slower boat that is me seems to have got its act together. Here's the result: An explanation of what it it comprises is at http://www.mcgee-flutes.com/Concertina/Concertina%20pneumatics%20lab.htm An interesting little challenge that came up too.
Wondering if concertina repairers ever resort to pressure testing the seating of pads? Pad seating is critical in flutes, but it's pretty easy to do a suck test, so most flute repairers just do that. Being somewhat of a fetishist, I use a Magnahelic Flute Leakage meter to refine that test. The Magnahelic is essentially a combination of a small air pressure generator (an aquarium pump in reality), a regulator to reduce the pressure further, and a Magnahelic differential pressure meter, which is what gives the unit its name. The Magnahelic is set up to read 8 with the end of the tube op
