Ron Moosaman rote, 4/12/96: <<Bill, a thought from an old player rebuilder, This could be done mechanically ................ Long week, just getting around to reading this stuff. What do you think?>> I was imagining this same kind of thing a chamber cylinder with an interior valve stem with valves at either end, with the valves such that one would be open and the other closed and with the travel of the stem set to alternate the opening. An earlier application of this is the hand water pump. But I was also imagining that something like this was an off the shelve item among industrial engineers and that someoen in this list my have tuned the piano of one such. It's been a long week up here, during which I realized that all I needed to do to serve my purposes was to turn the output pressure down to 5psi. At such a low draft, the air current is acceptable. But I sure enjoy talking with someone else who toys with ideas. Bill Ballard PT NH Chapt.
