We are down a tech, so I'm doing press scans. Paper machines have huge 3-4 story press sections that press water out of a forming sheet of paper. They dewater through 'nips' or very closely machined rolls that literally squeeze water out of the sheet. The water is carried away by 'felts' a arcane term for huge 30 40 foot across and perhaps dozens of feet high nylon fabrics that absorb and then carries the water away. I enter these press sections, which are incredibly hot, slippery, and full of rolls and felts moving at hundreds of feet per second to press a mechanical device against the moving felt, to get a profile of its performance. Weirdly, I like it. Fuck up and you are dead but I feel most alive when I'm doing it, it's something not everyone would do but its a rush. Hard to explain.
