Imgur gallery updated, and after those pictures, sanding commenced.

The neck appears to fit well in the pocket and it is not loose and doesn't seem too far off center if at all. It's hard to tell without reference.

The guitar is nice and smoooooth after sand 1.

Question:
I know the mantra is 'sand more' but ballpark in terms of 'how long should I be looking at', what's the sort of time range on sanding, cause all the videos seem to do it for like ten minutes, go through five grits and go 'nice'.

Cheers!
