do any of you get your wrenches calibrated?
and if so how often?
and where do you take them?
My Snap On roundsman takes mine away for calibration. But only when I have a problem or suspect something. They charge around £40 here.
You can check it the easy and free way. If you hang a known weight a foot from the center of the socket it should 'click' at that reading. So if you hang a 50 lb weight 1 foot out then it should click at 50 ft/lbs. Then adjust the wrench just above and just below that reading and see when it clicks and when it doesn't. That should tell you if it's reading in the ballpark. You could probably do the same thing with a bathroom scale but it wouldn't be as accurate. Just stand of the scale with your hand 1 foot from the socket and see when then scale reads 50 lbs lighter.
What are you working on?
Have you dropped it lately?
How often do you use it?
Do you go over the set torque just to get a little more turn on a fastener?
just wondering cause we have to get ours at work sent in for cal all the time, just wondering if anyone had thiers checked or not
Ahhh; didn't realize you were asking about work. You're with the E-6 squadrons, right?
Anytime you're using a torque wrench on something critical (for home use, internal engine work (heads, mains, rods) or brakes means "critical" to me...) it should be checked periodically for calibration.
I worked at a civilian helicopter place where the Chief Inspector checked everyone's TQ wrenches quarterly for calibration; it was an FAA requirement for the company to keep it's Repair Station certificate (HUGE deal in the civilian-aviation world).
not asking aobut work, i know ours are kept up, just wondering about the wrenches that are in most of our garages
For working at home I prefer a beam type. They're not as easy or convenient to use as a clicker, but you know when they're out of calibration.
I just bend the needle back to zero.
We have to cal check them at the setting we're using them at EVERY time at work. I think they go into the cal lab every 60 days to get adjusted.
Team Torque does mine www.teamtorque.com was about $30.00 plus freight for mine last time. Oh and they are quick about it too with good customer service.
I've taken mine by the PMEL lab on base and they'll let you do it yourself. I've never done it here at tinker though. I can't imagine it would be any different.
