I have a Dr Parts neck, 22 frets, no overhang that I want to fit to a standard body. I have thought of cutting along the pencil lines I have marked: I won't hit the truss rod, so I foresee few problems with that operation. There is, however, one more issue with this neck: even at the 21st fret, it is too wide. The reading there is a shade under 57mm. The neck pocket is the standard 55.5mm, which means that 0.75mm has to come off each side of the neck. (I measure in metric, but I am conversant in English, too.) Is doing this just a simple matter of filing and sanding off the sides, followed by a refinish, or is this adjustment so fiddly that I should just buy another neck?
