When I worked for the Airline that was one of my things to do. Going around
and calibrating torque wrenchs. Anything over 150 pounds I took to a hydralic
torque tester. Up to 150 there were torque testers spotted around the shops.
To bad I don't go to work any more. Maybe there are a few around your local
A&P service at the airport.

So I just bought a hefty 600 ft-# 3/4" army surplus torque wrench to assist
my
declining physique in removing tight bolts as well as for a couple of >150
ft-# torques I encounter from time to time. Anyway, it says it was last
calibrated a coupla years ago. I checked it against my 37-year-old Craftsman
1/2" click-type torque wrench, and it appeared that the 1/2" wrench applied
25% more torque than indicated! Checking it against a beam-type wrench
confirmed the 25% figure.
So anyone know of a place in the SF East Bay that does re-calibration? San
Jose has a coupla places but that means a half-day trip to get it done, or
packing and mailing.
