Well this was my fingerboard glue-up number 5 or 6 so I have very little experience.. I'm trying to find a method that works for me. On another neck I was doing now I had the heel already routed to size so I used pipe clamps on both sides and that kept the neck from slipping sideways at the heel.. I clamped a wood block to the headstock to limit forward movement. And this was enough to get the fingerboard where I wanted.
I think in the future I'll be trying to always have ~2 cm of wood left over past the heel so I can do the above trick.
About CERN - the time to visit is before now and early 2015. After that the LHC starts up again and there's no more going underground.
Anyway - progress has been slow lately, for Etna I'm a bit stuck on the body since I want to test an idea I have on scrap and this involves the whole front of the guitar, for the neck I'm ordering inlay dots for fingerboard work is on hold. The flying V is slowly advancing, I did the 12th fret inlay - this is my current design:
first take the template and drill the 4, 5 and 7mm holes
superglue, insert dots (white mother of pearl in this case), wait, sand flat
