Used to know a machinist who had micrometer fingers.  You could hand him a
piece of material (paper, metal, etc.) and he could tell you how many
thousandth of an inch with pretty amazing accuracy.

|He's kinda right. The notion that you would torque a fastener
|by hand runs counterintuitive to owning the wrench, in a way,
|but there is some truth to it. You can learn what a certain
|pull is if you pull it enough. Of course you have to figure in
|the length of the wrench you are using, but you learn that
|too. My dad used a torque wrench only a couple of times in my
|life that I saw; the other times he was "torquing by feel." He
|sure worked on a lot of stuff torquing by feel. He also
|snapped off more than his share of bolts. I use a torque
|wrench were I can, and by feel where I can't.
|
|You figure it out the same way you can tell what something
|weighs without using a scale just by hefting it. Same thing.
