For Bolt On Type Necks:

Your neck comes equipped with a neck block,  truss rod and two Allen head hex bolts.  Your block may be pre drilled for this hardware.   Hence,  in order to avoid having to re-drill the block or modify the bolt holes,  please note:

Before gluing the block into a rim assembly or sound box, the block should be modified using the following procedure:

Note the position of the block when dry bolted together with the neck. The block should have its top edge marked and shaved with a saw cross cut so as to sit recessed below the neck’s top surface (where the finger board gets glued).  The amount of this recess should be equal to the thickness of your top or sound board, usually about 0.100” (2.5MM).   The cut should also be angled using the same pitch as the specified neck angle (usually 1 ½ degrees).  The finished cut should be parallel with a straight edge projecting beyond the neck’s top surface.  Thus with the sound board in place, the finger board should lie dead flat beyond the joint in direction of the  sound hole.

Alternate procedure if the pre drilled block is already incorporated into the rim assembly:  the hole alignment can still be made good by using a concave sanding dish or  a pad sander.  Such a dish is commonly used in profiling rims (28’ radius is typical of tops).  The amount of material which needs to be taken off the block/sides at the neck joint is again equivalent to the soundboard thickness, assuming the block started out dead flush with the neck surface.  The surface can thus be sanded,  testing along the way for bolt alignment. You are done when  the bolts align and the resultant gap is the thickness of your top.
