I sent the following post last week but many members of this list were away at the convention. Forgive me,but here it is again. Hopefully, some of you lucky ones who were in New Mexico will have an answer to my problem, otherwise I guess it's "calculator-city" Thanks. Date: Mon, Jul 17, 1995 0:43 GMT From: Wippen Subj: Bechstein Treble Wire Scale To: pianotech@byu.edu Help!!! I 've got a problem . I am rebuilding a 1902 Bechstein Upright, Model V (85 note) Serial Number 28557 and I have misplaced (read lost, the dog ate them.......) some of my tear-down notes, namely the treble wire scale micrometer measurements. To tell the truth, I didn't have much faith in those measurements anyway, as the piano has been re-strung previously and I regarded the scaling as I received it as specious. Do any of you have this scale in your files? If not, I guess I'll have to do all the measurements and calculations [sigh :-( ]. O well. This piano has 28 plain wire unisons beginning with C#3 to the treble break, then 28 plain wire unisons to the top A7.( each string in the top section is individually tied). There are 15 Single bass strings and 14 bi-chord unisons. The bass bridge is an extension of the treble bridge. Any help would be much appriciated. BTW, does anyone remember the Klepac Chart. It was a method of devising a plain wire scale for a piano by measuring the speaking length, finding that length on the chart and reading the wire size. I never used it, and don't plan to, but ran across a copy while looking for my #@!%* teardown notes. Did this ever have any validity? Just wondering. Paul Dempsey Marshall University wippen@aol.com
