This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Doug, Sorry to hear about an undesirable experience. I've had a couple of = similar experiences as well. It's not fun working in an environment you = find hostile to your well-being. The sleds you referred to are interesting. I don't have the official = story on them, or an official name for that matter, but I know what = you're talking about. I tuned an SF-10 just yesterday morning. This is = only speculation from observation, but I would guess it was an attempt = to design a precise front speaking duplex. On the one I tuned, I did = notice that the front duplexes were singing away, and very much in tune = with the fundamental of the string. I didn't take note if they changed = intervals as I went up the scale. I suspect that they do. It seemed to = provide a crispness to the top end that was more uniform in nature than = just random duplex noise (just an opinion), but did not seem to work so = well up through the top octave. Up that far, the fundamental tone of = the speaking length kind of gets lost amongst all of the other racket = going on, at least on this particular piano. If I recall correctly, = they pretty much look the same upon first impression, but upon a closer = look, they appear to be all different, and have their own special place = in the layout of things. I don't remember that they are numbered, but = on a major repair I did on one a couple of years ago where it was all = dismantled for plate refinishing, (just a small part of the job), we = were very careful to maintain them in their proper order and put them = back accordingly. It is indeed possible that one or more of those = little Allen screws (the little buttons) holding them in place could be = loose, I can't remember just how they go. You mentioned that there was = a string or two just barely 'zinging' on the heads of those screws. You = might be able to get to it from underneath with the action removed, and = push aside the middle string far enough to get your little Allen wrench = in there to tighten... that is if you can stand the cigarette smoke long = enough to even pull the action... I'm sure there could be a whole added discussion on the qualities of a = duplex which are and are not desirable, tuning / mistuning, energy = dissipation, etc... (and perhaps one will follow?). But overall, I do = find it interesting, and I do have to commend Baldwin for having tried = new things such as the vertical hitch pins, the plate support system = (sorry I can't think of the name?), and these little duplex 'sleds'. =20 What do you do when this person calls to schedule their next = appointment? It's your call. I just hope you'll be able to be truthful = without being mean (not that you would be...) It may very well be that = this person doesn't even realize that their house stinks and is = offensive to others. I suspect that this person would probably be a = little hurt inside to find out that you were physically sickened by your = visit with her. Perhaps she does know, but hasn't dealt with the = problems yet. Either way, she's a person, and likely, at least on some = level, has feelings of dignity and respect that could easily be trampled = upon. Our words have a big impact on those around us, especially at = those vulnerable times of life. I'll have to relate a few of those = experiences some time. A wise man once said, "Do unto others as you = would have them do unto you." Sometimes it's hard. But it's worth it.
