One of my regular tuning assignments is the only Yamaha G7 I've ever met. Yesterday, I lifted the lid off to plug and snug the hinge screws for the third time. There's about a half pound of duct tape residoo (yes, by gawd, that's an "s" word!) on the underside of the lid, and four holes where sundry attempts were made through the years to (apparently) temporarily affix microphones of varying morphological configurations thereupon. I can't help but wonder how these hinge screws are pulled out repeatedly unless someone is closing the lid on an extra fat mic cord strung out the tail. In spite of the number of times I've tuned this piano through the years, I've never seen it mic'd, in spite of the overwhelmingly impressive evidence that it has been - repeatedly. It's probably politically motivated elves suffering no discernable thought processes that come in after hours and tape microphones to the lid, then slam it on the cord repeatedly. It's the only scenario I can come up with that fits the evidence. Even so, since the piano's in the choir room in the basement instead of in the sanctuary (CFIII there, with a small mic glued to the soundboard), there's no way firing up an amplification system on a 7' piano in that small space wouldn't kill or cripple at least half the room occupants. Perhaps that explains why I haven't seen the responsible elves. "Responsible elves", now there's an oxymoron. Then again, they might be using the lid as a penitential activation mechanism and/or hosanna extractor/motivational device for neophytes, nimrods, and convert prospects. I sure hope not, since I fixed the hinge mounts again. Passin' strange. With the lid off, this piano exhibits a lot of brass too - in the form of bridge pins. With our steel bridge pins being 0.076", 0.086", 0.096", 0.109", and 0.135" for #6, 7, 8, 9, and 10 respectively, these ranged from 0.097" in the treble, to 0.111" from mid-tenor to low tenor, with 0.119" in the bass bichords, and 0.147" in the monochords. Still tunes pretty clean in the treble after all these years too. Anyone got the modulus of elasticity of brass (whatever flavor) handy? A quick shuffle through what I have on top here didn't produce anything, and I'm too burned to dig deeper tonight. I'm curious about a stiffness comparison. Since the thread title here serendipitously happens to be "errata" (imagine that!), I'd like to take advantage of the implied breadth of subject to say this. Given the fact that it's the end of the year, and the general populous is swarming in suicidal frenzy like flies before a freeze, and given that this country has elected itself into a corner of congealed insipidity, instead of the usual endearing buffoonery with psychotic overtones, and given the list participants' work load, with accompanying stress levels precipitating the need to blow off accumulated adrenalin in random belligerence and knee jerk backlash reactions, and given that normally acceptably functioning social survival brain cells tend to go dormant under these circumstances, this strikes me as an opportune time to wish you all a merry Christmas and happy New Year. Now, do you suppose there's any way we can scrape off most of this childish crap and get back to pianos once in a while? Ron N
