Oscillating Twin Engine Kit
Oscillating engines were, in the past, popular for there simplicity and low maintenance. Also, because they were relatively small and light, they were often used for propulsion boats or on the farm. I built a model of the twin cylinder engine and again, I've done this in an unusual way. For its construction you will need basic workshop equipment such as a drill, hacksaw, files, sandpaper, glue ...You will also need source of compressed air (compressor) for running.
