You ever work a rig overseas in the middle east?
One raghead to tighten & one raghead to loosen for each and every joint, nut, bolt, coupling, ect on the rig
I was in Harbor freight the other day and one employee would not leave me alone like always asking can i help you blah blah blah so I asked him if they carried adjustable metric wrenches he said he would go and check well he never came back
One mechanic in one of the underground shops was replacing a complete front axle assembly on a Sandvik 1400 loader. He spent the whole shift installing it backwards...... yah that's right. The pinion was facing the bucket instead of the transmission and he left it like that for the next shift to finish up....... STUPID
