Shimming Soundboards

[Fenton Murray]

I've thought of using old boards for shims, it seems to me they would have
to be laminated to be thick enough, as long as you had the glue joint buried
in the board so it wouldn't show, it would work out. It would be a shame to
plane down to a glue joint, right when you were level with the board. Spruce
back posts from old uprights would be great.
