I believe I have seen setups where deadweights are used to calibrate the 
torque wrench.
This is what I would use, if I were going to calibrate one, since an 
accurate deadweight
is a reproducible standard.

For a lot of applications, extreme accuracy of the torque wrench may not
be 
totally necessary, if the evenness of adjustment of the clamping force is 
more im****tant than
the absolute magnitude of the force.

Still, most of us would not want to pay money -any money - for what is 
supposed to be
a precision tool, only to get something that is embarassingly imprecise.

Maybe we could get some car magazine (or even Consumer Re****ts) to do
a series on this?
