Follow Chip's instructions and you'll never willI've never seen a neck split in half like that and I hope I never do !!!
For a while Patriot and Dynabass necks had 2 options ; 1.5" or 1.7" nut widths. Options were later dropped as Peavey fine tuned their production methods.I thought the neck profile was slightly different and the width at the nut was wider
Those production methods also account for supposed differences in profile. See it's common to see the term "CNC" banded about when folks talk Peavey , truth is the early machines were mostly glorified pin routers. Differences occurred due to the unfinished template blanks reacting to temperature , guides getting worn etc , it wasn't by design
