Hi Lads Whats the reasoning behind calling say a 6" rule a scale in the USA ? Rob |
| Joe d:
Ask George III.... he was the last RULER in the US :lol: :lol: |

Hi Rob, A rule is a conclusion derived from a set of axioms. A scale is a set of spacings. This was a definition from the US National Bureau of Standards -- back when the US had such a thing. (It has been replaced by the National Institute of Standards Technology which is an Institute dedicated to the protection of intellectual property. Their 600+ page charter makes no statement whatsoever about promulgating of enforcing standards!) |

Ignorance? From what I've learned, a scale is used by draftsmen (or draftspeople, if you prefer) to make a drawing to a certain scale. A rule, by contrast, has increments in real world dimensions. It's unfortunate but most people do call the little flexible pieces of steel with numbers on them "scales" and you get a weird look if you call it a "rule". |

Is there any company selling foundrymans rules these days? Edit to add:I should have said patern makers shrinkage rules which are in fact scales rather than specific measurement rules. I found one here: http://artisanfoundry.co.uk/store/product_info.php?cPath=32&products_id=208&osCsid=932b7bbb45af1524a27fd64a7709dd8e |
