I used to hate adjusting the USAF wrenches. Avionics was the shop that did the bases. Everything from 1OZ jewelers screwdriver types for NVG's to 1000ftlb ones for the mounting of props. Sucked big time since every time they were dropped they had to be re calibrated. Totally threw them off. Plus the calibration cycle was every three months also. So a few hundred on base meant job security for all!
