I've got a friend called Mick. He's an engineer. None of that big stuff for my mate Mick though, he works with small stuff. Really, really small stuff. The picture below is of something he makes.
Just to put it into perspective and to give a sense of scale, the big object is the tip of a ball point pen.
The needle thing is 0.3mm diameter and increases to 0.5mm diameter. Once Mick has made these, they go off to have a slot electro-eroded into the thick bit. Yes, they cut a slot in that .... and then they weld two bits of metal into the slot!
Amazing stuff.

This happened in the sixties when we could be proud of our engineering of course...
