Yay - I got some stuff done over the weekend.
Made the neck pocket template, tweaked the neck template to suit and cleaned up round the edges - mostly with a top bearing router bit, switched to a bottom bearing bit on the sections most likely to tear out.
So the neck is now ready for the head cut & drilling for the truss rod top nut at tonight's "lesson".
I also tweaked my thin chamber rout template to add the neck pickup cable rout, marked it out on the top & bottom body part and got busy with the graphite conductive paint.
I'll cut the pickup cable channel tonight so I can slap some graphite paint in it when I do a second (& third?) coat.
The graphite paint I used is a water-based product from catmussic99.co.uk - Guitar Shielding Paint. It goes on quite well, although dries pretty quickly, but it does cover well - that's about 1/3 of a 30ml bottle.
