Just flicking through it. There's some pretty good ideas here, and a few I've since proved unworkable. However I especially like the drawings of things I sketched out as soon as I came up with the idea, went on to make and they are now part of a machine.
I think I've just come up with a blinder of an idea. Need to order some metal and start turning it into reality. If this works it could save me a small fortune in brass casting. I really need a prototyping department, where I can send drawings and say 'Make this in steel and get it back to me this afternoon.'
