    Default How is chain Measured?

    people talk in inches about chain measurements. Are they measuring the

    a) External Length of link
    b) External Width of link
    c) diameter of metal used in link

    or something else...

    It's the diameter of the metal.

    If you want to use chain on a windlass, you need "calibrated" chain, which is manufactured so that each link is the same length. Strangely, there seems to be no standard for windlass gypsies, so the only way to ensure the chain will work satisfactorily is to try it on the gypsy. Some chain manufacturers sell chain calibrated for specific makes of windlass.

    to avoid confusion, a pednat writes: the diameter of the rod from which the links are made.

    It has been known for a chain to be measured across the diameter of the "0". [img]/forums/images/graemlins/blush.gif[/img] ahem.
    I think, therefore I am. I am, therefore I sail.

    [/ QUOTE ]Good point, I don't think the original poster would have been confused, as he asked whether it was "the diameter of metal used in link". However, you're right to point out that there are some people who are easily confused, so it's always best to try to explain things as simply as possible.

    In terms of chain to fit windlass gypsies, whilst true that there is no "standard" in terms of pocket design/size, they are manufactured to specifically fit a given calibration of chain.

    Most European chain will be calibrated to DIN766, whilst American chain tends to be ISO. The designed calibration should always be mentioned in the manufacturer's literature.
