I have just received the new 7/32" ID tubing from Schaff Piano Supply
Co. It is product number 605E, at $8.75 per bundle of 50 feet. It is
perfectly suitable, just enough undersized to slip on 7/32" nipples
easily, but tight enough not to pop off. Just the ticket for later
model Aeolian Orchestrelles, which used miles of the stuff. If it
matches the quality of other Schaff tubing, it ought to last a long
time, and stay tight on the nipples.
Craig Brougher is to be congratulated for arranging with Herb Johnson
of Schaff, to get this essential product stocked. It fills a long felt
need in our work.
