Post subject:  Neck carving formula
Hey Folks, i was wondering if anyone knows of a neck carving formula? I've come up with
my "numbers" for the 1st and 12th frets but am concerned about leaving the minimum amount of wood
behind the truss rod slot which I believe is .125. I don't want to go to thin! I've heard of this one, but want to be sure. OS=F+TR+X(remaining wood behind the truss rod slot)
Thanks a bunch.

If you don't mind.... please explain what you want a formula for?
Is it for neck width, neck thickness, Neck profile, something else?

It would help if you expand your variables a little bit....

Thanks

I use a common truss rod which gets install 7/16" below the fretboard plane. I also like a pretty slim neck and I've gone as thin (including fretboard) as 0.790". Now I make my fretboards 7/32" thick too, so that gains me 1/32".

So, yes your formula is what I tend to use, although, you really want to know what a "standard" neck thickness is. They can range from slim 0.780" to thick 0.950" or more.

So for me, this would be the formula at the nut.

Since I know my total thickness desired and my fretboard thickness desired, along with the depth required for my trussrod, I know how much material is left in the neck.
Total-FB=neck
0.83"-0.219"=0.611"
Neck-TR slot=remaining
0.611-0.438"=0.173 which is just over 11/64 so, I have more than the desired 1/8" remaining wood.

This is not really a 'formula' per say, but rather it's just doing the math based on known criteria.
