I've got a Norbar torque wrench, owned it for around 40 years!
Might be time to check that it's still accurate, is there a way to do this, at home and without a lot equipment?
Thanks

quite a few youtube videos covering it, its quite easy with a bit of maths and a hanging weight scale

Norbars where manufactured by MHH Engineering. This is them now and they can still repair and Calibrate most makes gedore-torque.com

It will come in handy even if you never use it

After 40 years you can pretty much guarantee it needs calibrated. ISO recommendation is once a year.

If you work for a production outfit, they will tend to have calibration benches they used to check their tools daily. It may be tricky to know someone who would do this for you, but you never know.
I've had mine checked this way.

Thanks everybody, I'll have a look at the youtube vids, hope the maths isn't anything more complicated than 2+2!
