Without standards there would be chaos in industry. At the beginning of the industrial revolution, each shop had their own design for nut and bolt threads. They did not interchange with other shops! I believe this was one of the first industry standards.

That would be a nightmare... I would go absolutely insane working on anything

Oh, you're from Montana! The Swedish flag threw me off.

Doesn't really change anything about what I said, but somehow I feel like it's different writing to someone in another country.

Haha, sorry to confuse!

Remember when fuselage pieces of 787 from different continents didn’t fit together, and what a giant fiasco that was? Still amazes me something like that could happen. Took two years to fix it.

A friend has an MGTD. Parts are available, including leeever shocks, but he’s found that the hardware is all in Whitworth or something. Not just the threads, but the bolt heads are all different and have their own wrenches.

There is a place in Lyons, NY That sells odd British fasteners, oddly enough, called British Fasteners

Sir Joseph Whiteorth is a distant relative, so now you know why I start so many threads, or I’m a nut case.

The real fun Is when you reach for a BSW 1/2 wrench, you better be trying to loosen a 9/16 hex head. The wrench size references the shank diameter, not the hex size. Just another reason the sun set on the Empire

[BlackBart]

Wow...just wow. I would go crazy. I've been spoiled all these years just reaching for a 15 or a 17. Other than my high school tool box (graduation present to work on my Bronco) I have no other English / Imperial / US tools (does a pipe wrench count?). I recently bought a string of tiny 1/4" Imperial sockets for all those annoying hose clamps!

Good family story!

He wants me to help with "trunnions" and "kingpins!" or some such poppycock!

Moment of silence for the Empire.............

Alla hagel sverige!

That's fascinating. I remember the atomic clock, growing up near Boulder.

Isn't there a process going on recently to redefine the kilogram with a reproducible scientific recipe, rather than compare to a master weight stored somewhere?

Precision (or even semi precision) manufacturing can be hard even when all parties are in the same country and use the same measuring systems. One company I worked for was making aluminum rings about 2 feet in diameter for a new customer. The parts were shipped to the customer and the customer would reject the parts as out of specification. The problem was found to be our shop was not all climate controlled and the rings would shrink or expand as the temperature varied.
Another time we were making simple welded and machined brackets (like alternator or compressor brackets). We made them as we normally would make similar parts for our own use. Most were rejected by the customer. In this case, the customer specifications were on the drawings but were much closer tolerance then we normally used. We stopped working for this company soon after. This is referred to as firing your customer.

Honestly, to me this sounds like whoever in your company bid said job was at fault. If the customer's requirements were unable to be met by your company, then it should've been declined. If the job required more precision at a higher cost, then that should've been taken into account.

I deal with designing/building test equipment machines and fixturing and sometimes I have specifications that are kind of tight tolerance-wise. I expect the vendor to be aware of their capabilities and price the bid accordingly.
