Applying accelerator first with a syringe  can help in some situations.  Need to wait a few minutes before applying the CA if you use the accelerator.  Make sure you use a sharps container to dispose of the syringes.  They are very dangerous, especially if disposed of incorrectly. I haven't done this on high level grands, but it works wonders on old Kawai grands.   I started with verticals.   Tim Coates University of South Dakota University of Sioux Falls Wolfley, Eric (wolfleel) wrote: <blockquote type="cite" cite="mid9BA6DCC15456CC46894E77233173DD7CAF704F@UCMAIL5"> <pre wrap="">Thanks Fred....I think I'll go practice in a practice room tomorrow.

I really don't think there is anything to worry about overmuch beyond the aesthetics. IOW, if a bit of CA manages to get in what your imagination will tell you is a bad place, it won't have a noticeable effect (this from experience with less fine instruments, where I have CA'd entire sections - capo - without worrying overly much about where the flow managed to get to, and noticed no ill effects whatsoever. Worrysome places being between string and bridge, and in the pin/ notch/string interface). That said, on the finer instrument, I am very careful to control the CA as much as possible. I like to use a very fine end (as in ZAP ends), and apply to the bridge side of the pin right behind the string, watching it wick. Just enough to wick into the crack between pin and bridge. As Roger suggested a while back, a bit of paper towel or similar, placed between string and notch, will absorb what might flow over. Controlling extra thin CA is a trick, and best practiced in the practice room a few times first. I have had reasonably consistent good results. IOW, CA has always reduced false beating, and usually come close enough to eliminating it. Well worth the effort (very minor expenditure of time). Seems to be reasonably long-lasting. I haven't been doing it long enough to vouch for long term in multiple years - I guess two years is about the limit of my experience, best I remember.

It seems to me that you would have to lose a certain amount of power since sound is coming off the bottom of the soundboard as well as the top. I know these units have great value in studio and home situations, but I just can't imagine it not affecting the piano's tone and power. And by the way, just as a reminder about how this thread began, I haven't heard from anyone about gluing bridge pins on a concert instrument...it seems like a great idea to be able to stabilize the wood around these pins. I guess I'll just have to go up into a practice room and find out for myself... ~~~~~~~~~~~~~~~~~~~ Eric Wolfley Head Piano Technician Cincinnati College-Conservatory of Music University of Cincinnati ~~~~~~~~~~~~~~~~~~~~ -----Original Message----- From: Don [<a class="moz-txt-link-freetext" href="mailto:pianotuna@accesscomm.ca">mailto:pianotuna@accesscomm.ca</a>] Sent: Friday, October 10, 2003 7:25 AM To: College and University Technicians Subject: humidity control in concert pianos Hi Jeff, I've changed the thread. That's very simple to arrange. Take a rechargeable emergency flashlight, replace the bulb with a buzzer and splice it into the power cord of the DC unit. When the unit is unplugged it will buzz for about 20 minutes. Trust me--they will plug it in! I'd really appreciate the DC people including this as an optional "add on". A refinement to this would be to use one of the many uninteruptible power supplies that are used on computers--I do think this is overkill--but I'd do it in a flash if I could purchase a unit where the "beep" could be turned off for concerts--there would then be no cords needed during a performance. The local University concert venue's here have DC units on the two pianos used for that purpose.
