I saw this actual model at the Model Engineering Exhibition in London - around the bottom of the model when exhibited he had a wooden plinth on which were mounted all the cock ups he had made when constructing ... these showed us the size of the pistons - gudgeon pins - bearings - cranks - all hand made and scratch built. Incredible engineering ... and as you can see it runs
One limitation - you can't scale oil down - so it overheats quickly - he can only run it for very short periods
Of the crowd of us gathered round it one wag said 'My wife would never let me spend that many hours in the workshop!'.... a voice came from the back of the crowd 'If I could build like that I would't want a friggin wife!!'
