Box building frame now finished, although still needs levelling up.
After much rescaling from the plans, measuring and careful cutting / positioning all of the vertical frame supports are now built.

OK, I've started some boat building related stuff at last
Began the building frame tonight..
Phew there's not going to be much room in here !

First challenge, the floor is nowhere near flat or level, going to have to do some careful packing and bracing.
