[pianotech] OT Soundboard Novice

[Allan]

Those are all very good questions. These matters have been discussed a lot
on this list with input from extremely knowledgeable individuals.

I have never yet done such work myself but I would sure search the archives
and read all that have been said already first.

 

Go to www.ptg.org <http://www.ptg.org/>   and use the Search Mailing List
Archives box at bottom right with keywords: ribs, crown, soundboard etc.

 

There is so much to read!

 

I wish you good success.

Hi all,

Please excuse these questions, but I want to do the best job I can. I am
going to attempt my first soundboard restoration on a 1915 Wurlitzer
nickelodeon for my own collection. The piano deserves a screw-polishing
restoration.

    To begin with, how is a soundboard crowned? Are the ribs actually curved
before gluing? 

How much deflection from a flat plane is used. Is the soundboard a parabola
or a true convex lens shape, higher in the middle?

    Can an old soundboard be re-crowned?

When making a new soundboard,why not use old soundboard wood?

 

To most of you these questions are juvenile, but I truly would like to know.
If I have to, I will job this part out. (There is a great RPT near me.
[Lance Lafargue]) I have been restoring automatic instruments for a long
time, but never had to so anything before to the soundboard other than
refinishing, bleaching, shimming, etc. 

Thanks!
