I have just started a new project, well at least working in a feasibility study as that gives a way out if nothing materialises ! The new project is to be a working 1/4 scale model of a 1934 Mc Donald Australian tractor. The full size tractor has a bore of 9.25” and. stroke of 10” and is a 2 stroke single cylinder diesel with reed valve air induction. I am lucky as the full size tractor is only 17km away and I have access to photograph and measure it up. So far I have taken about 60 photographs and spent 6 hours on sketches. I have also started to make the cylinder/crankcase pattern as I needed to check some external details with the full size tractor. As part of the exercise I have gathered information on the history of McDonald and a copy of the owners manual . The photographs show the early stages of the pattern that has yet to be rubbed down and painted with spray big. George.
