Torque wrench calibration...who does it?

[Spammy]

How about a ghetto DIY calibration? Put the socket end in a vice and hang a known weight at various distances out from the pivot and see when it clicks.

That would be a way to measure the wrench, although you can buy torque checkers relatively cheap nothing compared to the calibrater's equipment. But making the adjustments to the wrenches is the hard part.

A mate of mine owns Torque Calibrations - he's Sydney based but gets shit sent to him to fix / calibrate from all over the country...

Ask for Matt, tell him Fatboy recommended him to you...

We use these guys I believe..

clamp square of torque wrench in a vice, measur out 1 foot from centre of square, hang known weights off 1 foot mark on handle...

Sorry about my prev post-- just noticed you had beaten me to it.

This is a digital torque checker you can buy analogue ones that just screw to a bench or wall, these are used for quickly verifying your wrench if it is out then you call in the calibration guy.

Got a link to that?

It's a norbar, we have one on the wall at work.. Handy

No sorry I found it in google images looking for analogue ones.

You wouldn't want to hear the price on the snap-on gear like this then.

Read a great post on either the Commo or Ford forum where some dude recommended using a torque wrench to undo caliper bolts so you can work out what they were torqued up to originally by reading off whatever torque was needed to undo them.

What is the point of that unless you are Grissom/CSI? Non-lubed threads could be oxidised as fuck making the reading pointless?

So how far off can torque wrenches be out? I never get mine calibrated?

My (admittedly 20yr old) china cheapy was actually clicking at 40ft-lbs when I set it at 60. I went and splashed out on a Warren and Brown.

'tight enough, but not too tight'

I have a big 3 foot torque wrench, had to buy the bastard for the crank bolt on the viper, although putting it back on was the easy part
