broken plate

[Farrell]

Hi Del. I read your response regarding the replacement "B" plate. I
understand all including the need for a new pinblock, except the need for a
new soundboard. When the old cracked plate was installed, I presume the
rebuilder was content with the condition of the soundboard. I would think
that you could keep the existing soundboard and just recap the bridges for
proper downbearing with the new plate/height. Or are you assuming the need
to reposition the bridges because of small differences in plate geography (I
don't know how much variability there is in plates I guess)? Thanks

P.S. my soundboard salvage project is looking more positive all the time!
