I’m working my first scarf joint neck. The neck is glued up I have the truss rod installed. ( allen nut Hot Rod) Just kind of curious where the brass piece should be located on the nut side. I usually put line it up with the nut. If I move it down a little, I could use a smaller truss rod cover. I can also cut the allen wrench down. There will be a top plate on the head so some of the truss rod slot won’t show. The truss rod dose slide in the slot it’s not loose takes a little tapping. I did put a little silicone on the rod. So how critical is the Brass pieces placemen in relation to the nut. I put up some pictures one has a drawing were the brass is now.
