Not long ago, this video from School of the American Rifle popped up in my feed:
After watching the video it occurred to me "Hey dummy, you have torque testing equipment at work. It's kind of like, part of your job description." So I took my Fat Wrench to work and tested it. Our standard testing is 25 rundowns at 50% of the tool rating so I set the wrench for 30 in-lb and started my rundowns. I've had the wrench 3-4 years and primarily use it to torque red dots and mounting plates so it's not in heavy usage at all.
Here's the list of rundowns, what the torque tester actually read and the average over 25 rundowns with the percentage difference.
I was surprised by the amount it was off. I'm not sure what I'm going to do at this point. I may pop the top cover off and see if there's an adjustment to bring it back into calibration. Or I may just add 20% to the called for specs of whatever I'm mounting. I'm not upset or anything because I don't use it very much and when I do it's for generally non-critical tasks. If I were doing some kind of agency work, critical assemblies or otherwise making a living with it, I'd be on the phone with Wheeler tomorrow.
Anyway, I figured some of you might find this interesting and maybe entertaining.
