Finally got my first torque wrench calibration right on the third try
I've been an A&P for about 18 months now and I always dreaded doing torque wrench calibrations in the shop. Last Tuesday I had this old Snap-on wrench that was reading way off on the tester, like 15 pounds low at 100 inch-pounds. My lead mechanic just told me to take my time and make small adjustments, so I sat there for 45 minutes tweaking the spring tension a quarter turn at a time. On the third full pass through the test points, everything landed within 2 percent of spec. I was honestly surprised it clicked so well because my first two tries were all over the place. What I learned is that rushing through the setup just makes it worse, and a few patient adjustments beat trying to fix it all at once. Has anyone else had a torque wrench that just wouldn't cooperate no matter what you did?
