what a stupid thing to do

I work with greenhorns right out of "Installation and repair" and "cable maintenance" schools for Verizon telephone and those guys know jack about how it gets done in the field. Similar to old cars and new mechanics, the 2 just dont go together well. Experience is worth it, and the classroom environment with all its pretty new tools and meters doesnt make it out the front door. I dont understand the mystery of R&R rear ends, dial indicator and a torque wrench and a manual.
