Another good day. Starting at 6.30am, constructed the last pillar of tyres, completed the drainage ditch round the circumference, shifted all the main beams into place (thanks to Pete and Pavlik for giving us a hand with those) with plastic sheeting between tyres and wood to provide a moisture barrier, put first coat of petrol/used engine oil mix on remaining beams and second coat of undiluted engine oil on them all, and cut noggins from our stack off offcuts from the woodyard.
All that’s left now to complete the basic structure is to fix the noggins in place and engine-oil the undersides of the flooring, then we’ll be ready to start laying the floor. Could we get it finished before we have to leave again at the weekend? Maybe. Just maybe.
