inky pete Posted August 28, 2009 Report Share Posted August 28, 2009 The ball bearing and machine made nuts and bolts. They made possible the transition from home made rough and ready machinery to the efficient, powerful, precision engineered technology of the Industrial Revolution.

observer Posted August 29, 2009 Author Report Share Posted August 29, 2009 Funny you should mention "ball bearings"; it was considered a key target during WW2 (Swinefurt raid); designed to cripple German war production. Quote Link to comment Share on other sites More sharing options...
inky pete Posted August 29, 2009 Report Share Posted August 29, 2009 There's not much in the way of machinery which doesn't use bearings of some description. Definitely a high priority strategic target in wartime. Quote Link to comment Share on other sites More sharing options...
