John Clarke constructs a miniature replica of Richard Newsham’s innovative fire engine, which was granted a patent by George I in 1721. Martin Johnson explains what really goes inside model boilers and how he constructed an accurate computer model for predicting their behaviour. Roger Backhouse spends an engineer’s day out at the Denny experimental model ship tank at Dumbarton. Wide-A-Wake finally arrives at the day for its launch. Ramon Wilson describes the completion of its engine rebuild and its introduction to the water. DAG Brown ruminates on repetitive machining and reveals how he goes about the mass production of cones for injectors. Wolfgang Tepper continues his description of the construction of an unusual opposed piston two stroke engine, which possesses one cylinder, two pistons and three connecting rods. Anthony Mount makes a water pump for his Ferrabee stationary engine. Martin Gearing fabricates the body of the boiler’s hand feed pump and provides a few pointers on the art of silver soldering. Graham Sadler demonstrates how to make a tailstock die holder. Terence Holland begins the construction of a new boiler for his Barclay well tank and describes a useful tool for forming shoulders on the ends of the tubes.
