I installed the top outboard stringers of the seat-backs and the little blocks at the rear of the top panels. The best material at hand for these gadgets was a 42 mm thick off-cut of Celery Top, which I liberated some time ago from the waste bin of my favourite timber supplier – I knew it would come in handy one day.
A bit of glass (off-cuts again) will protect and water-proof the floor of the rear section of the seat-back (i.e. storage compartment). While things were curing … I made up and installed the reinforcement blocks and inside cleats for the Dorade boxes.
