gluing the parts of the neck together done Hmmm, this end of the aluminum tube will be visible through the pickup cavity. I have to plug something in. Lets take a pine stick cut off a little piece of it and shape it like that with chiesel and sandpaper so I can plug it in firmly. Few drops of CA glue are also in there and some rough sanding - i need the surface to be a little bit rough to glue the aluminum false-fretboard (lets call it so - I mean the neck surface that will be under the glass fretboard) preparing some stuff 2-component epoxy glue that is labeled "specially for metal surfaces". Here I have to say that it is exactly the same epoxy glue that was used for project #2 (look in the first post). It had an aluminum fretboard, that was glued on with this epoxy to the aluminum "neck". The result was great. Few years later I tried to tear the fretboard off without success.
