Torqued the same bolt three times in Denver, each reading was different
The old Snap-On torque wrench never lined up with the digital one after a cold snap last January, so I spent a morning rechecking every fastener on a 737 flap track and learned to mark the barrel position before trusting any calibration sticker.
Three bolts in one morning is rough, I feel for you on that. Calibration drift is a sneaky bastard, especially after a cold snap messes with the internals. Marking the barrel before trusting the sticker is the kind of lesson that only comes from wasted time and a sore arm.
