Hi all,
I've read somewhere that engineer's levels have an astonishing degree of sensitivity. Though they look pretty similar to the spirit levels we DIYers are familiar with, they are *far* more sensitive to the extent that if you so much as place a thin slip of paper under one end, it's enough to send the bubble markedly off centre. And as we know, our levels wouldn't even begin to register such a minute change. So does anyone know how this extremely high degree of sensitivity is achieved? I was just wondering if it's possible to make one up (they're an arm and a leg to buy!)
