Out come the go bars again and I fitted the back to rim, 'closing the box'.
There was one section close to the bass side waist that the gap needed much encouragement to close! That's why all 60 go-bars were used.
It was so warm yesterday that I had to slow the gluing process down somehow. I painted water onto all the gluing surface of the kerfed linings. Then I went round with the mini glubot and trailed a line round the whole lot and smoothed with the my finger. I wiped up any dribbles down the inside which occurred at the brace housings.
I then went round again with the glubot leaving a line of glue around the whole rim and some more on the neck and tail blocks, and then clamped the back down.

You might notice that I made a tapered dovetail blank to fit in and protect the tapered dovetail housing in the neck block.
This morning I removed the go-bars.

I then whizzed round with the bearing guided cutter, at half speed again.

That area of the waist that needed encouragement to close?! I managed to find a gap about 10mm long and could get a .003" feeler in about 3mm which suggests to me that the kerf lining was glued to the back at this point. The feeler would not go all the way through. So, when I rout the rebates for the binding and the purflings, the kerf join will still be sound.
I taped my phone to a stick to try and video the inside of the box and look for any defects, but they're taking an age to upload.
EDIT
Yer Tiz. Must sack the cameraman and get a better one!
