While I was a student I had a summer job at a septic tank factory. There were two large new Italian machines that made 2m high by 1.2m wise x 70 mm thick septic tanks. The tanks were formed inside a HD steel cylindrical form containing steel mesh by a massive piston that spun while it was hydraulically lifted up inside the tank. Concrete was mixed in concrete truck sized mixer about 20ft above the ground and carefully dropped onto the slowly spinning piston which spun the concrete outwards onto the walls of the tank. As the piston was raised 6 large (400mm in diameter x 100 mm thick) steel rollers/impellers on the rim on the piston compacted the concrete hard up against the mesh and tank form. I could go on . . .
One of my jobs near the end of the day was to clean up & diesel coat the exposed steel parts of the machine ready for the next day. The giant pistons had to be disassembled cleans and the reassembled. Disassembly involved a set of large truck spanners and sockets, some length of chain, and a forklift. Despite the machines size and ruggedness it was nicely made and parts of it were even precisely made. To aid assembly there were dozens of 6mm alignment pins and we were constantly losing a few each day on the concrete covered factory floor when i asked the foreman about spares he showed me how to make them using 6mm galv weld mesh with an abrasive saw and tidying them up a bit on a bench grinder. After about a month I noticed there were very few original ones left. despite the massive forces involved the newer pins seemed to work and last just as long as the originals.
As a student I really liked that job as it was easy and well paid and moderately interesting. Unfortunately it was not available in the following summer but I managed to find a job labouring in high rise construction which was interesting in its own way.
