What's it like to work with this piece of machinery?

"The loom can be very cantankerous and I have had to learn a few mechanical tricks to keep it in good repair. There are parts that are rigged with aircraft cable and it eventually breaks and needs to be replaced, sometimes mid-project. The brake mechanism consists of heavy rope, springs, turnbuckles, and bar-bell weights that hang from arms on the two large back beams. It is all mechanical, nothing automated. Some have asked me if it is some kind of work-out machine."  This American Maker Uses a Custom, Artist-Designed Loom to Create Geometric Textiles by Heather Corcoran
