- When you fit the neck with your heel block you will notice that the top plane of the neck will be on the same plane as the top of the heel block. Prior to installing your heel block you will need to remove a small amount of material from the top of the heel block in order to accommodate for the thickness of the soundboard. The neck and heel block should be installed so that the plane of the fingerboard is aligned with the top of the soundboard. The top of the heel block will be lower than the plane of the neck by precisely the thickness of your soundboard. You may need to remove additional material from the bottom of the heel block in order to achieve the final thickness of the guitar body. When removing material from the top of the heel block you may expose the top of the hole that is drilled for the truss rod. It is ok to expose this hole.
- These pre-carved necks are intended to have the nut mounted on the flat or fingerboard area of the neck. This is different than the nut placement on some Martin® guitars where the nut sits on the angled part of the headstock. Using a ¼" wide nut (such as the N1) seated in this way, and a fingerboard slotted to a 25.4" scale you will be able to line up the 14th fret of the fingerboard with the end of the neck cheeks –where the neck meets the body.
