Take one old beat up pressure gauge

One cheap electric clock movement

Cut the guts out of the gauge

Replace it with the movement and hey presto you have a pressure gauge clock.

Its amazing what you get up to when your bored

I trust you found something interesting to do with the Bourdon tube and mechanism, Stew

Maybe when I visit the UK we can go for a pint at about 25 psi.

I don't drink pints only feet and inches but yes any time your over we'll make it a date.

I've got a bourdon movement that would probably fit that clock case…

If it was a metric pressure gauge it'd be time to go to the bar…

When I was working, TIME = PRESSURE. in pressure terms, 0 Psi = breakfast at home, 70 Psi after the morning meeting, Mild panic at midday, no time for lunch. Most pressure came towards the end of the day at 300Psi so the clock was about right.

I can see that in some arty farty antique shop selling for around £300! So I suggest that we all have a rummage under the bench and start producing antiques for the future.

Never thought of it in them terms:- working under time pressure, or pressured by time, lack of time pressure etc etc.

What about time in nautical miles perhaps !.

Not you as well. It’s bad enough with Doubleboost doing it.

I’m going to get an old clock and make it into a pressure gauge.

Calibrated in lbf per square nano-light-second?

Stewart,

Instead of batteries (or winding), you could have used the air spring.

Was reading 'Echoes of the Oil Country 4' last night & Bill Osborne talked of using a modified pressure gauge as a dial gauge. This was 1901/1902. Seems redundant pressure gauges have been used for other purposes for well over a century.

Regards,

Richard.

The nautical miles option should do well in Germany! They have a system of 'Engineering minutes' for timesheets etc with 100 minutes in the hour!

Hi I made this to compensate for this by adding an unloader valve

Happy being retired this device is working perfectly for me.

Re the idea that people have been converting pressure gauges to other things for decades…people have been committing murder for millenia, it doesn’t make it any less wrong!

I’d not make a clock to gauge conversion using pounds per square light second. That would be mixing units.

I’ve had enough now, I’m off to the bar…

You're all wrong. What you're actually doing is measuring time as a unit of pressure.

If we are mixing units, then that would be 14.7psig then, Carl

Would time run backwards if you applied a vacuum to the ‘air spring?

as a nano light second is near enough 300mm, what you actually mean is lb/sq.ft, which is a pretty small unit, but not as small as the pascal.
