Yes. It is certainly unforgiving. In the BP plant study I did I found that supervisors wouldn't ask hourly to do unsafe jobs, but they would do it themselves. The other big finding was there was no process for updating training manuals when something in the process changed. Without constant diligence, the manuals eventually became worthless. When I wrote about the program at Bayport, the training manager there was ruthless. Nothing slipped through the cracks, and it showed.
Today, due to some errands I had one very short hour in the shop, but did get filler set #2 almost finished. But I was rushing. When I'm rushing I make mistakes and have to do stuff over. "There's never enough time to do things right, but there's always time to do things over." At least today there was.
Bending the new one in reverse wasn't easy since not every bend was reversed. Everything went okay until I got to making and soldering together the vertical support tube. For some reason I cut the first on a good 3/16" too short. Soldered it all up and went to put it all together on the H-beam and it was way short of the end when I went to put on the bottom support. At first I didn't know what I was looking at and then realized that the whole thing was wrong. I de-soldered the tube, cut a new one and new diagonal brace (longer) and soldered it together again. I needed to be redone anyway since the first one's soldering was not up to my standards.
Then after putting it all together, and setting it up for a picture comparing it to the other one, I realized that I mounted the whole arm upside down on the H-Beam. I had to break lose a glue joint and reassemble. The picture now shows the correct position with a clamp holding the glue joint.
Tomorrow, these will be finished and mounted on the loading platform.
