question...what is your finish neck thickness....before fingerboard>?....just curious
For my fast / Thin Necks...I have a finished neck thickness of 17-18mm....(truss rod thickness is 9.5mm (LMI)).. FB wood is 8-9 mm....for a total thickness of @27mm...or just over 1.06"
These ones (each one I make has been different) are 13/16" at the nut and 7/8" at the 12th fret with the fretboard. The fretboard is probably around 1/4", so that makes it 9/16" (14.2875 mm) at the nut and 5/8" (15.875 mm) at the 12th fret without the fretboard.
