I managed to finish the stand-off hings but it required me to take off all the knuckles and start again. But, with that hing in place, I've been able to move on and make the inner box. this is tubular and designed to sit inside the outer box. It will be held in place by six rods which will be screwed into the body of the inner box and held in place on the outside of the outer box by a set of hemispherical 'features'.
The following pictures show the inner box (without its lid) inside the outer, with the first of the holding rods in place. In the first picture, you can see one end of the rod protruding into the inner box, having passed through the outer wall. this picture also gives you a good view of the outer box hinge.
The next picture gives a view of the rod from the outside of the outer box, with the fixing feature in place. The rod will of course have to be trimmed to size.
The final picture, above, shows the rod passing through both boxes in a bit more detail as well as showing the smaller standoff hinge on the inner box.
