For those of you who might want to try your hand at making a Ridgewing body or body part and putting it up for sale, to help get you started, here are the complete metric hole patterns for the bass and treble frames/grills or other inserts. Nominal hole diameters are 4mm for M3 attachment screws. This is intentionally a pretty sloppy hole position tolerance so you can feel comfortable using a hand drill. It all comes out in the wash when the guitar is finally strung up and everything pulls snug.  Then you can easily and precisely adjust the neck angle and intonation to your liking with the neck pocket micrometer adjustment screws.
