Welcome to Model Engineer 4534
We start – at long last – the new series by George Punter who is describing the making of the engine for his 1919 Saunderson & Mills agricultural tractor. The model’s chassis was described about a year ago but now we get into the heart of the machine.
Patrick Williams makes a pair of very neat wooden boxes with which to transport and store his Minnie traction engines – the engines that featured recently in his article about setting the valves.
Jacques Maurel has been thinking about a universal screw cutting attachment and has refined a design he presented ten years ago.
Graham Astbury fitted an extractor fan to his workshop in order to improve ventilation and his own health. He describes the method.
The Garrett 4CD now has the differential finished and fitted and the back axle assembly is nearing completion and Mariner gains three connecting rods.
Journeyman looks back at the time when steam locomotion was was appearing in America and, back home, at a high speed oil engine by Clayton & Shuttleworth!
