You've gotta be in Auckland.....it's even painted !!!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..
