During the mock build I've noticed that the neck is slightly too big for the neck hole at the top. see the photos below/attached.
reading the forum it is clear that the alignment and fit of the next is essential so what is the best solution to get best fit?
I figure I need to have this sorted before I embark on any sanding and finishing of the body and neck...It may be a simple sanding job to get it all snug but I wanted to check to avoid mistakes so early on.
