Thanks, ChalkLit
Regarding your question, here's the official word from Marc:
I do glue the FB extension to the top but here is where I probably differ from most builders of bolt on necks. I glue the FB to the top without removing the top finish. Theoretically this should not work but I scuff the lacquer under the FB and what I get is adhesion that holds well but can be released if the neck ever has to come off. I also use liquid hide glue here as it separates more easily than normal wood glue when heat is applied. Most builders remove the finish from the top where the neck extension will go. I’ve seen the top pulled up when trying to separate it and it’s not a pretty sight!
The guitar is finished and would have shipped this week, but we're trying to work around our fussy Canadian weather! The current plan is to ship next Monday, so I should have it by next Wednesday. Thanks everyone who has been following along - I'll try to do this thing justice with a great review and some clips
