Found a great book called 'Machine Devices and Components Illustrated Sourcebook - ISBN: 0071436871' . It's full of drawings & explanations of mechanical fixings, linkages, cams, fasteners & mechanisms, etc without going into loads of theory & calculations. Only problem is it's a bit expensive at £54. Amazon was showing it at £45 but I might see if I can get the local library to order it (Unless anyone on here's already got a copy & wants to flog me it
).
