Wire

[Eric MacEachern]

What is the difference between spring wire and tension wire? I see both terms used in clock parts catalogs.

thanks, -Eric-

OK, I'll give it a try!! Spring wire is soft and bendable to form a spring. Tension wire is good for click springs, and is hard and somewhat brittle:?|

Got it. So spring wire would be used for putting tension on levers, such as a strike hammer or a count wheel lever. Sort of an elastic tension on a lever as opposed to a compressed tension on a click?

I suppose that you would fit whatever was originally used for things like strike hammers and other levers.

Such springs appear in various forms - some clocks use spring strip, others shaped steel springs or hard steel straight wire.

Fitting springs where there were none originally is usually a bodge when someone is too lazy to find the actual fault! :o
