I found one.
I phoned around all my friends, who are all retired and mostly ex tradesmen. One of them found an old 9/16" whitworth, which is also 5/8" British Standard, which just happens to be 1" AF.
The other end is a 9/16"W and 5/8" BS .

And you lot wonder why metric is so popular!

I think this would be a collectable now, it has to at be least 70 years old.
Now I just have to work out how much is 12 ft/lbs without being able to use my torque wrench. And i thought this was a simple bolt on!!

Bob, now you have me flummoxed. Does this mean that 1 inch is not necessarily 1 inch? How many inches are there? I thought it related to a standard Anglo- Roman thumb. I know about Imp and US gallons, but I always assumed the inch was standard. Even more of a marvel how the guys landed on the moon 50 years ago.

I suppose you could attach an extender to the wrench, and attach a 12 lb weight at 1 foot from the center of the router shaft, while lying the router on its side? Provided we are talking about the same foot, and the same pound?

You should still be able to find impartial weights from shop scales, in some of the junk dealers in Cyprus. There was a place in Larnaka that still had WWII era British military radio headsets - bound to have some old scales from peripteros.

Biagio, without going into a 50 page history of spanners (yes, they are spanners, NOT wrenches) in the past, there were dozens of ways of measuring bolts and nuts, hole diameter, bolt diameter, size of circle the nut was shaped from, etc etc. and every manufacturer made their own and sized their own, to make customers have to buy parts from the makers. So around the end of the 1800's a Mr. Whitworth attempted to standardise them all, which is where the "whitworth thread" came from. Which then became British Standard. But of course even then we has BS coarse, BS fine.

He was quite successful, but then the Uk learnt about metric and it all went to hell again.
And I havent even touched on the american SAE, and others because america is still only about 25% metrified (if that).
To make it even worse, this musclechuck nut measures 1"AF Which is stands for Across the Flats.
60 years ago when I first started using spanners on my motorcycles, I always though AF stood for American Fine thread, which just shows how screwed up things are.
Its hell out in nut and bolt land.
