Report ESP M-II type "Invaders" Superstrat in In Progress and Finished Work Posted 8 hours ago So this planned out perfectly. Note that the centreline on the headstock part of the Maple deviated at a very slight angle from the body part. The centreline was extended down the headstock by eye. This isn't easy, however a piece of blue tape provides a high contrast "target" so you can tip the blank up and down to sight whether it's to the left or right of centre. Moving the tape and repeating until you're on the mark isn't too tricky once you get a feel for it. Over such a distance, any error is in the magnitude of a mm or two which can be borne in mind for any futher calculations made around the headstock. Once it's on the CNC, it'll be what it is with reference to the edge (57,5mm parallel off the centreline) however it's enough that the wing tip glueing can be considered. The neck portion of the blank measures 25mm in thickness and the headstock 26,4mm. The final thickness of the neck will be brought down to 21mm on the CNC (after a bit of mass stock removal on the jointer) which will advance the neck to headstock transition line a fair distance (4mm of depth at 13deg is 17,3mm if you do your trig). the headstock itself will only receive a skim cut to establish a plane referenced to the CNC. It's safe to say that the transition will move about 15mm along. This needs to be considered if I am to glue on a piece before the CNC gets its teeth into there. The overly-thick headstock is good for the moment, since it helps with stiffness during initial machining. The first neck process showed that the headstock wanted to bend under tool pressure. This isn't an option. I may still figure out some sort of auxiliary workholding jig that supports the headstock from underneath, however I'd want to make that adjustable rather than a one-shot jig.
