DMiller, You are correct, we are a bunch of old mucks, and our tools are getting quite old too. I wouldn't trade or sell my tool box full of tools for anything...Tools are for buying not selling!!!
Anyhow, you have made me think, hmm, I have not had my Snap-On click type torque wrenches tested in a looong time. My newest torque wrench was the 3/8" digital, and it is gone! So, I looked on the internet, and found some sites that give you step by step on how to test the accuracy and adjust. I also found sites that offer calibration services. Honestly, what I was looking for was Snap-On's calibration service. I know years ago the tool truck guy would take your torque wrenched and send them out for calibration, and that is what the Snap-On site says today
"Give it to Snap-on and we'll make all the adjustments it needs, clean it up, replace worn handles, and have it back to you in no time"
I think I will contact the Snap-On salesman that services our school and discuss this with him. Since I am not in an actual shop that the truck comes to, it makes it more difficult. In the meantime, I may just give the step by step how-to a whirl, if for no other reason but to see if they are close.
I have always stored my torque wrenches in the blow molded plastic boxes and the value backed all the way down. It will be interesting to see if they are still accurate. I think the fact that I do not use them professionally (not to often) will help them to remain accurate.
Found this on several sites:
The actual "Click" from a wrench is considered a "Cycle" of that wrench. Most manufacturers recommend click-style torque wrench calibration after 5000-to-7000 cycles.
For most customers, this means you should calibrate and test torque wrenches every 12 month
