Ship models, largely in bone, by French prisoners of war in the Napoleonic wars, trench art, a full-size glider and various models by WW2 POWs, medal-winning models made with machine tools most would think incapable of any kind of precision, and then, of course, all the works of craftsmanship and art in history and pre-history, made using hand methods, with tools often made from materials that we would consider hopeless, clocks and watches and so on and so on. Once I start thinking about what has been done by people who know how to achieve the impossible with nothing, I start to think that I should just pack up and slink quietly away. I need all the help I can get from precision machinery to de-skill tasks, as much as possible.
