Acoustic Guitar Construction

The only thing I'd change from that would be to tighten the neck and heel end a little - like at most 1/4 inch - to anticipate springback. Perhaps drop the waist 1/8" or so for the same reason. Don't overthink it.

Wont' hurt but simply not something I've bothered with ---- key to no spring back is bending the waist curve first on a pipe. Plenty of info here about that, we bend sets almost every day -- we simply copied Taylor's process. Quantum improvement in quality plus zero cracked sides.
