Salutations fellow kitters.

Well I'm equal parts excited and terrified about my first build.

I've overcome my first hurdle which was a neck heel that was WAY too tight by sanding back the four contact surfaces.

I'm a fraction worried about the back now, as on the high side there is a gap (see pics). Do I just keep sanding the under side of the heel until it sits flush?

Can someone shed some light on where the neck should be set too? If I'm sanding and shaping, I want to know that I'm doing it to the right position. If I was a hack, I'd place the pickup in the body, and assume that where the PUP cover ends is where the neck should start. But I'm smart enough to know that there's probably a lot I don't know.

Thanks in advance all. I'm really looking forward to this, and perhaps it turning into another hobby to hide from my lovely wife!!

Jeff.
