BSW (British Standard Whitworth)

[JamesAC]

My mate and I devised a measurement system based on the BSH - the British Standard Handful, for measuring ladies, err, chests.

Graduated in whay heys?

Kiera Knightly will be measured across the flats I guess.

Anyone know the common name of my avatar (at time of posting)? Very pertinent, I'd say...

Moreover, astronomers are plagued with Whitworth and other non-standard threads all over their equipment, to the despair of those wanting to standardise. Why is this? I just put "Whitworth" into the search box of one of the Astro forums and came up with plenty of hits! I suppose it's the old story: American influence (q. why do Americans use BSW = British Standard Whitworth? )

Whit was a standard thread, it was first made common across the railways and was adopted by the car and aircraft industries. It was only when the Americans got involved in the war that they wanted a unified thread form and the Whit started to fall out of favour.

And that is all I remember on the subject from my Engineering Degree many years ago,

Could we not start a campaign for the standardisation worldwide of screw threads.

I suggest the British Standard Cycle Thread.

As a total non-sequitur...................

Does it peeve anyone else that electrical items such as plugs, junction boxes, light fittings etc appear to be designed with maximum irritation to the installer in mind?

There never seems to be any coherent theme running through the design when it comes to fixings. Some screws will be slotted, others, cross-head, differing sizes, some brass, some plastic, some steel, the odd nut thrown in, all on the same fitting, and if a screw needs fixing 'in-situ' then the odds are it will be in an impossibly awkward position and almost invisible to the naked eye.!


There, I feel better for getting that off my chest.

As you were.

Touché, I should have said "non-metric". At least threads in cycle bits and pieces are mostly metric. Or are they (*waits to be corrected*)?

Am I on my own in stating that I love an Archimedes Screw.

Anyone seen the big one at Edinburgh airport? - fascinating, I'd love to see it in action so to speak!

might I ask - what's with Italian BB threads?

Obvious................they work best in reverse.
