Acoustic Guitar Construction

Discussion is good!

Naturally next question: Do you think a good guitar develops some kind of top raising, or should it stay "flat".

This question or rather the answer -- is basis for perhaps the most repeated and misunderstood guitar making myth -- and that is the notion that Martin guitars have bracing that is contoured to 28' The fact is Martin makes "flat top guitars" (actually the X bracing is contoured to 52' to prevent the look of concavity) The myth stems from the fact that under string tension the doming happens! And I guess that when measured "ta da" it calculates to about 28' -- start with 28' bracing when constructing and the under string tension dome is something else, and be assured it is no longer a Martin design.

The myth stems from the fact that under string tension the doming happens!

Well, I splitting hairs now, that brings me to the first subject.
If a ball park "flat top" raises from 52'to 28', that would be about 1 mm/0.004" in the center. Then, in a proper setup, string height to the top lowers 10%. I think I'm gonna consider that when setting the neck on a new guitar, as I wrote above.
