I think I spent more time watching video snippets and reading portions of other articles to give myself a lightning course on weaving jargon, just so I could understand what was being talked about in the OP. And suddenly, why looms look as complex as they do and are able to weave complex patterns makes sense. Why looms were automated makes sense, and I find myself with a new sense of respect for those who learn and master operation of a manual loom. It's not a trivial task.

Still haven't been able to figure out what a "differential sett" is. Searching with quotes on google finds a bunch of stuff talking about '"differential sett"lement'. Or stuff about Egypt. Best guess is that it has something to do with using a number of threads per inch that is different from what is set on the reed, or differs across the breadth of the warp.
