This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Well, being a born dinker arounder, I have tried most things in this = regard. The only thing I have personally found usefull is a bit of = finger pressure down and sideways on a string right at the forward = bridge pin. This works quite often really for very slight adjustments in = pitch. I have been left suspecting that there is something about how the = string meets the bridge and pin that doesnt really get dealt with by = regular string seating at the bridge and have it on my mind to play = around a bit with different possibilites for bridge string termination, = but thats another story... grin...

Thank-you Graeme = Harvey, Susan Kline and Joe & Peny Goss, for your help. I am specificly collecting technicians experiences who use use = wooden, brass, or other tools, to push or massage the wire, in order to = make fine pitch adjustments. If you have some positive results, and use = a tool to this end (other that tuning hammer technique) in your work, = please post me at my personal e-mail address. I will collect the info = and report updates and progress to the list.=20 The goal of the research, is to see if there is a reliable and = predictable technique, to make fine pitch (lowering) adjustment in a = solid wire unison, where hammer technique is difficult, or not accurate = enough.=20 The premise and background of this study is as follows: (Unison = checks from an arual technicians perspective...) We get the unison as close as possible with hammer technique. Then, = we compare the pitches of the three wires, with 3rds. 6ths. 10ths. etc. = If one of the wire is found to be slightly sharp, (and hammer technique = too course), we lower the pitch using the tool.=20 These techniques can also be used to lower single wire (outside = wires being muted) pitches, as in strip-muted octave setting, or in = making fine adjustments in setting the temperment. =20 Thanks for your encouragment. =20 Dan Reed Dallas Chapter ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
