....more armchair politics (Part 1)

Oh, very, very good. :joy: :joy: :joy:

Imperial measures are not really this issue though.

Our sock puppet prime minister is.

It certainly feels that this dark money is coming home to roost with the tories
Many people must be shitting themselves knowing they are toothless to denounce the Russians.

Talking of this, where are the blitz kids ERG?

In his country they are advertised and sold as such for the radius, but they are manufactured to metric drawings, width of course is in mm and the ratio is a combination of the two :scream:

Whereas Universal Beams (and the far less popular RSJs) are sold in Metric sizes but are really just the old imperial sizes converted.

e.g. an old 8" x 5 1/4" UB became a 203 x 133mm UB

Obviously, still made with the original tooling.

I have a friend who works in military engineering, he’s late 20s, and he says that thous are still used in dealing with tolerances etc

Probs because we buy loads of gear from that America

At the point of my retirement (6 years ago) they were certainly used in our engineering shop far more frequently than microns.

Lots of very old but still very good lathes with imperial markings/read outs still kicking.

I’m pretty sure he said that they used metric measurements with thous for tolerances

What does that mean?
A thou of what?
As far as I know a thou is a thousand of an inch.
In metric they would just use millimeters or decimals of that.
I have never heard of a metric measurement being say 7cm + 5 thou, it makes no sense at all
Unless a thou is 0.1 of a cm. ie 1/10 of a millimeter, but that doesn’t make much sense either

Most engineering drawings I have seen don’t use cm at all, Everything is in metres and millimeters

Metres and millimetres in the building trade. It amazes me that some guys younger than me, still work in feet and inches, I don’t get it.

Where I was our drawing office was fully metric when I arrived (1989) to the extent that when the Americans supplied us with a whole set of drawings for a large Marx generator we had the whole lot transcribed into metric. This, despite all the actual dimensions staying the same, as they had to given that we would be filling the thing with the Americans’ imperial-sized capacitors.

I did once or twice hear the older workshop guys use some imperial measure or other to describe surface finish, but it tended to be in the context of “How shiny do you want this thing I’m making for you to be ?” to which the answer was rarely very critical.

True, yet timber’s supplied in multiples of 0.3m. And scaff tube was when I last had anything to do with it (admittedly a very long time ago).

You’re right, that makes no sense because 0.1cm is 1mm :woozy_face:

Oh yes, we had a few years of “metric 8 fts” etc.

I will continue to operate in Fucktons.
