Stop in for a cup of coffee

We used to have to calibrate the 600lb torque wrenches they were fun to break. The C-130 had a huge prop nut think it was over 1000 ftlb, they used a torque multiplier on them.
Torque multiplier. I have a story. A young tech at an ag dealer drove their multiplier with an impact wrench. Needless to say it was explode inside.
