No one likes to admit it, but it has happened to everyone at least once. About 10 years ago i was working nightshift (4pm-4am) in a large workshop. It got to about 2am and I was real tired. My task was to fabricate 20 sections of gas pipeline, so I was cutting the seamless pipe (300mm OD, 40mm wall from memory) into lengths on the power hacksaw. After cutting 6 I ran the tape over one to check, and my stomach turned when i realised i had cut all the sections at 8260mm when they were supposed to be 8620mm. Being pipeline the stuff coudn't be welded, so it was all useless.An expensive mistake, and the only time i have been fired.What's your worst example of not double checking at work?
Reply:I was fabricating some runway beams for an overhead crane, and they were 24'-11 1/2" long and I cut the first one 24'-1 1/2" long. I usually mark several and then re-measure before cutting, but cut the first one and realised I forgot to check my measurements. I would have cut all 10 if I wouldn't have stopped to re-measure. I went to my superviser, told him what I had done, and then he said I was lucky that we had another job coming up with the same size beams and that I could use that one for nubbins. Now I measure all beams 3 times before cutting.
Reply:Middle 70's working for an off road Mfgr. The saw operator was off sick and I was pulled off the boring mill before the fab shop had to be sent home...The band saw was a Marvel 81A and I worked the morning OK (many skids of correct parts). The saw could be set for length and angle cuts on the fly.Anyway I took lunch and in the afternoon I cut box beams and never once set the angle called out on the print... Thinking I had it down I increased my output... Nothing scrapped but a lot of re-cutting, I felt really bad. I just didn't bring everything back to work after lunch!Matt
