When that didn't work the switched to bi-chords. Not a lot of expert design work went into these things. Mostly copying and trial and error. Del -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org]On Behalf Of Terry Sent: December 23, 2004 6:10 AM To: pianotech@ptg.org Subject: Third Bridge Got a good photo on my first day lugging my camera around with me! This is for those that might think a transition bridge is only to be found on high-end 100+ year-old pianos and high-performance recently-redesigned pianos. The photo below is of a 1962 Cable spinet (please ignore the cockroach crap). And of course, some clown is going to ask - "yeah, but how did it sound?" Silly question. I would describe the transition from plain wire to bass section as a two-step, less-bad, than some spinets. Somehow I don't think the less-than-perfect transition is the fault of the three-bridge design. Likely other factors involved. (Like maybe a soundboard made of rec-room-wall paneling?) You can bet your bottom dollar that a hockey stick design was tried first - that must have worked really well for them to justify spending $17 (or whatever) extra dollars on EVERY piano they built to incorporate this three bridge design! (Check out the nice, even, pinning on that little bridge!) Terry Farrell ------=_NextPart_001_01C3_01C4E8D4.DFEA94E0 An HTML attachment was scrubbed...
