Started gluing in the support strips for the Z ( this is going to take a while) with just enough of a ledge to hold in place.
Finally committed to how I am going to light the fretboard inlay with side lit optic fibre to eliminate any electrical outside the body. Drilled access hole from board to top of tang and trenched -it aligns fairly well with the wiring hole for the bridge pickup.
The veneer on the headstock is super thin with no sanding so will have to replace. That gave the option of back-lighting the MOP (earth) with optic fibre. So trenched to the headstock inlay and sunk in a chamber to accommodate the optic. The fibre will be sunk in putty back along the neck. The MOP allows some light through and will thin the back side a little as want it subtle. the routing doesn't look that pretty at the moment but wont be seen once putty filled and fretboard glued.
