Ray,Don't feel bad, I just cut a bushing 3 thou too much in ID. Fortunately not a lot of time invested in the piece but, wanted to finish it tonight. I have no idea how I screwed it up. I either started from the wrong offset or, I bumped the crossfeed dial with my midsection...
- - - Updated - - -Ok so I was working on a demolition job welding a shear attachment on a big excavator I got in the cab to move it into a better position to finish the weld I leaned forward and hit the boom down lever with my chest it punched the ground like king kong on crystal meth. Ooops did anybody see that? No. Good! except 50 ft of welding lead was coiled underneath it cut in four places anic:.
Forman just said "finish welding the @#$%^&* shear! We need it back on the pile". (Oct, 2011 WTC). I always walk wide around excavators.
All I can say is I am usually pretty tight lipped if I mess up! Been about 2 weeks ago I was running the line boring bar, at work, was a pretty small bore, where we were boring it out, and pushing hardened bushings into it, so I rough cut one side to within maybe .010 under, and I thought I would get a jump on things at the end of the day! I was rough cutting with hss cutter, and it was hot in the shop and I was tired by the end of the shift! When I got home I thought about it, and I had flipped the measurement, and I was actually, .010 over the bushing size! After 20+ Year's being there I have all the alarm codes, to get into the plant! So I told my GF Debbie what I thought I did, and we went down early Saturday, and did some welding and some minor boring and the problem was fixed, I did tell my foreman about it just so I was in the clear on things! So RAY don't feel too bad!
