Custom Piano Restoration / SB Designing

[RicB]

Hi Dale.

I'm curious about something that I dont think has really come up. I hope 
you are up for an answer.

In RC & S boards as they have been roughly described on the list so far, 
the primary (or certainly one of the main) concerns is to view the ribs 
as load carrying beams.  How does one go about avoiding ending up with 
one or more strings somewhere along the bridge(s) placed so that they 
can strongly excite a SB reasonant freq close to its own ?  How do you 
go about dealing with where soundboard nodes and nodal lines end up ?

Cheers
