ACME threaded rod is not a metric standard [whatever is advertised on ebay] ... The metric equivalent is called Trapezoidal.

Far from it !!

I'm sure that none of us has experience of the whole gamut of both ranges.

I think your "in my experience" probably explains it

Not all 'carbon steels' are equal

... and for that matter, not all 'High Speed Steels' are equal

Mark's comment is also very pertinent.

This may help a little, Tony: **LINK**

It's a joy to see those spirals just dancing out of the hole.

... very impressive.

There is more than a glimmer of truth in 'Gee Officer Krupke!" **LINK**

Thanks, Ian

There is something strange going on with the UK App Store

Your link works fine, and directs me to the App ...

but simply searching the store didn't show it.

Do you have a link, please ?

I can find no relevant reference to hague on the UK app store.

Sorry, John

Finding either of those values would require the data to be parameterised ... so you will first need to define your terms and then analyse every thread on this forum, to determine at what point each thread has reached your 'threshold'.

This may take some time ... and you are the only one qualified to do it.

Meanwhile; the rest of us can just have a chat about things that happen to interest us.

Just did a search using 'Duck Duck Go' ... which found this: **LINK**

Vic,

Browsing around ... I found this page: **LINK**

http://www.remark.me.uk/pages/workshop/projects/models/pittlerconst.html

The last line of which mentions: ...

the series of articles by Geo.Gentry in Model Engineer vols. 82 & 84

It might be worth you looking-out for those.

MichaelG.

Quite right too, Sir

Have any of the 3D CAD enthusiasts started modelling this machine yet ?

... It would seem an ideal subject.

It's worth noting that Harrison's first clocks [before the Longitude competition] were made mostly from wood.

This is a good place to start: **LINK**

Concerning Such Mechanism:

As a broad generalisation:

Most things that undergo a chemical reaction will do it more slowly at lower temperatures.

The theory is too hard for me 

But the relationship is exponential [on the Kelvin scale]

Well done

It must be destiny.
