Open End Crows Foot and Torque Wrench

[infinity]

I have some large bolts to torque on a transformer and due to space limitations I need to use an open end crows foot on the wrench. Does anyone have an idea how you would adjust the calibration of the wrench when using one of these? I was thinking of using it on an existing bolt and keep adjusting until the wrench no longer clicked and began to turn the nut but I was wondering if there was a more accurate method.

Here's the formula

It's very close if the crow's foot is positioned at 90 degrees to the wrench.

For fun check your spec. +- torque, torque to x-xx ft/lbs. then add the tools +- and see how it works with the number the formula gives.
I went round and round on a job over this until I showed for my application it didn't matter how I used the wrench, then QC had to go to a meeting suddenly.

exactly.

inline with wrench extends the "ft" part throwing off the torq.

leave it at 90 degree, torq away, done, next job.
