With my first build I'm pretty much done with the build (body and neck Tele heel). The neck fits nice and snug but not so tight that you need to force it in, just snug. I'd say good fit. The body holes (5mm dia) are properly drilled so the bolts slide through (no bite) but tight. My body is 3mm thicker than a standard Tele body i.e. 48mm and not 45mm so the bolts has 3mm less wood to bit into the neck heel. Heel pocket is flat and 16mm deep Neck heel is flat (as far as I can tell) When I screw in the 1 3/4 standard 4 bolts as tight as I can, there is ever so slightly up and down play - the neck creaks when I put bit of force (little) on the headstock). After investigation I see the heel isn't seated flush near the edge - there's some bulging around the screw holes on the neck. I sanded it flush again fitted, still creaking, but before I doing anything more stopped - the heel around the holes hasn't bulged yet much, but I can't keep sanding the heel down, I'm almost out of play with the overhang f/b to the pickguard. The neck wood is Sneezwood, similar qualities to maple and a propper hard wood. Should I try source longer screws? How much longer can one screw into the neck (is there any thing to worry about with deeper screw holes into the neck?). My 2 piece neck is 19mm with a 6.5mm f/b = approx 25.5mm neck What have I missed? What else can I consider?
