Excellent fab work again Peter, you have a nice lathe as well. Ah yes the shit plants. If i never work another one I'll be OK with that. We did the 48" intakes here a few years ago... kept clogging the 4" trash pump with tampon applicators. Really funny story tho.
They didn't use valves on the intakes, but they have grooves in the concrete that they drop a giant plate in, called a wier plate. Of course it didn't seal very well, so they got the idea of using sandbags to push up against it. So they took the flatbed and went and got a couple pallets worth. They backed up to the manhole and started chucking them in, so i walked over and asked how they would get them back out. They hadn't thought that far, so i suggested maybe tie a rope to them. Lol they had never thought of that, so they got some wire pulling rope and set to work. End of the job they pull the ones on a rope right out, but now what to do with the ones that they just bombed down in there? Then they started setting up a tripod, and we all had to see if they really were going to do what we thought... and then out walks the new guy, tyvek suit, boots and gloves taped with a fall arrest harness. They lowered him in, and moments later reeled him back up, him holding a sandbag, covered up to his chest in the most horrible mess imaginable. I may have puked, i don't remember lol. This goes on for hours, then when he couldn't reach anymore, they backed up a vac truck and sucked out the rest hahahahha.
Worst part of it was the plant sent a letter to our boss saying we were the most professional crew ever and we got done in record time. That was due to the fact that when breaks and lunch came around, none of us could even imagine eating, so we busted our asses so we could leave lol.
