Torque wrenches lie!

Ha! I like the sound of the bucket ... but what about friction in the pulley axle, Cam?! Maybe it would need ceramic bearings :ROFLMAO:

Thanks Tom - I'll find some joint to do it or else do the weights and measures method. Pretty sure we had a work one done through the manufacturer (Warren & Browne).

Lock down gets you do these things that you put aside for " later"....
Cheapo gauge , calibrated with water
Spreadsheet does the rest
Both my torque wrenches weres slightly off , so calibrated the " big" one for the upper range , and
the "little" one for the lower torques.
Jig is a bit overkill, but made from old stuff kicking around
Analogue gauge would be better to determine the "click off" point I reckon..

Well done. You actually went and did something practical while the rest of us were theorising. (y)

Don't put too much torque on it though. That the piss-weak cheapo strain gauge looks like it could easily be ripped apart by the massively over-engineered torque arm :) . I've actually got one of those little electronic luggage scales somewhere. I forget what it maxes out at.
