List,

    I am studying supplamental techniques to fine tune unisons... that is, I
am researching and testing methods other than hammer technique, to make
small adjustments to solid wire. 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.
    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.
    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.
    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.

Thanks for your encouragment.
