marking out an elipse the backwoods way

[magnet]

This might not be new to some but it was to me. What with all the people making wood burners for sheds and the like i thought this might be handy for stove pipe fitting.

 

[roofman]

simple but perfect

 

[Woody.v8]

Yes very good but it dose my head in when people say mille

 

[MattF]

You're not the only one who finds that somewhat irksome.

 

[gordon stephenson]

Used to drive me up the wall when working with American lads on turbine shutdowns when they insist on calling 0.001" (thous) mills,

 

[magnet]

Poor Tom Plumb came all the way from Wigan to deliver his pearls of wisdom and all you can do is pull him for his terminology he's old school, a feet and inches man not used with this new fangled metricness

 

[migmag]

Well how does your accent produce abbreviated dimension???

Great vidi thanks.

 

[Kent]

Nowt wrong wi that!

 

[gordon stephenson]

Wouldn't a milliinch be a millionth of an inch, surely a thousanth would be a kilo inch

 

[Woody.v8]

Wouldn't a milliinch be a millionth of an inch, surely a thousanth would be a kilo inch

Not sure, There are a thousand millimeters in a meter?

 

[Maker]

Wouldn't a milliinch be a millionth of an inch, surely a thousanth would be a kilo inch

Milliinch would be a thou'
A millionth of an inch would be called a microinch
Kiloinch would be 1000 inches

SI prefixes.

Technically they're metric prefixes but who cares...

 

[shedfull]

Yes very good but it dose my head in when people say mille

"Heighth" really grates on me, just does.

 

[Maker]

SI prefixes are all Greek to me - apart from the Latin, Spanish and Danish ones

I didn't see what you were getting at at first, very clever.

 

[julianthegypsy]

Why did I not know this? Brilliant. My customers can now watch me being all technically clever and accurate, instead of angle grindery and sweary!

 

[CRB]

I remember doing the same thing but with a piece of string. I can remember doing it, just how to do it.

Off for a think.

 

[Rocketman]

Milliinch would be a thou'
A millionth of an inch would be called a microinch
Kiloinch would be 1000 inches

SI prefixes.

Technically they're metric prefixes but who cares...

Could the milli naming in this particular example be something to do with 0.001mm is 1 millionth of a metre?

 

[CRB]

Well, yeah.

Still have not remembered.

 

[Rocketman]

Oh, and which example?

In the list of metric prefixes Maker gave. I was summarising the coincidence that 0.001mm is a millionth of a 1m.

 

[Rocketman]

1m is 1000mm
1000mm divided by a million = 0.001
