I was looking at torque wrenches not too long ago on either the Grainger or
McMaster-Carr web site (I forget which) and saw that they also sell torque
wrench calibrating devices. However, the low end ones cost enough to make
me want to stick with beam-type wrenches, and your last name better be Gates
if you want one of the high end units.
While writing this message it just occurred to me that it shouldn't be very
hard to build a tester that used weights of known values hung at the end of
a lever arm (yes, I know, the weight of the arm will have to be figured in
too, varying with the distance from the pivot point). The next question
that occurs is: Do the common click-type torque wrenches (Craftsman, SK,
etc...) have adjustments that the user can get to? Anybody know how to go
about adjusting one of these?
