That’s fine. The article/tag isn’t really about mapping “small engineering organizations” though. It specifically has to do with supposedly mapping “A place where a variety of parts are machined for different companies.” I think the fact that all you could come up with when you looked into the usage was “Regionally dependent, small engineering organizations” just proves my point that the tag is ambiguous and being used as a catch all on places that aren’t specifically machining parts.

In the meantime there’s already man_made=works for industrial manufacturing plants, which this tag is undermining. Like take Gearbox Group. They manufacture automotive parts. Why tag them as industrial=machine_shop in that case instead of man_made=works + product=automative_parts or whatever? Sure, as @SomeoneElse else says they are a “small engineering organization", but then it that doesn’t have anything to do with why product=* as an alternative to industrial=machine_shop makes no sense like he’s claiming. At least in the case of Gearbox Group man_made=works + product=automative_parts seems perfectly reasonable.

There’s plenty of other examples, Zagar Inc produces spindles. Why not use man_made=works + product=spindles there instead of industrial=manchine_shop?

Heck, take somewhere like King Machine Works & Powder Coating. They coat cars. It’s not even a place that machines parts.

There’s Hawboldt Industries. Currently tagged as industrial=machine_shop. They produce deck equipment. Again, not a parts machining place and there’s zero reason they can’t or shouldn’t be tagged as man_made=works + product=decks or whatever instead.

So aside from them being “small engineering organizations”, why exactly would tagging any of those places as man_made=works + product=* be nonsense? How exactly are places that manufacture decks or spindles machine shops?
