Sides On.

The sides and ends have been soldered together. Care must be taken to make sure all is kept square.
The lower picture shows the assembled body attached to the chassis. 12BA bolts are used to screw into the captured nuts on the ends.
The top photo has the frames bent down and a fillet of solder run along the etched folds to give a bit more strength.
The structure is remarkably strong, this is useful as a plastic roof from the Society 'B' Set is to be used on this coach. The aluminium on supplied by Worsley need too much work to clear the toplight windows.
