New production systems 1963 -part three
After a good nights sleep and a lot of thinking time I realised I might have a solution. My training at Harwell had taught me to think outside of the box, I had remembered the building of Wallingford school swimming pool. The 80×25 ft concrete base had been laid in one day and on going to see it late in the evening how shocked I was to see shrinkage cracks on the top surface, luckily it was only superficial but it made me very aware of problems when hot winds move over concrete surfaces. I decided to create shrinking conditions for the first two hours using fans and allowing more space around each stack of moulds. On using fans the problem was solved and the new production system had arrived, amazingly after 80 million products we still use this system today.
