BlownCorona Posted July 28, 2011 Share Posted July 28, 2011 It's just steel. What do you think the spring shops do? spent all day learning about bending metal today actually. at every point you bend, it messes up the grain and the hardness gets well and truly messed up. this will result in work hardening and very quick failure at those points. sping shops bend the metal (probably in one big bend) then heat the steel and quench it in water, this brings all the grains in the steel to the same point so its essentially one piece again.

When a spring shop reset leaves they only just warm the steel and slowly bend it in a press (start and one end of leaf and work there way to the other end). When they make the spring in the from scratch, the steel is heated to red hot, shaped using a jig, then cooled down in oil, then heated again to get the correct hardness. Then the spring is shaped and matched to other leaves in a press. Quote Link to comment Share on other sites More sharing options...
di0n Posted November 13, 2011 Share Posted November 13, 2011 I added two leaves either side in my KE70 and it's stiffened it up nicely. I don't think one leaf would be enough, well it wouldn't have been for mine. Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted November 19, 2011 Share Posted November 19, 2011 i thought they heated then used a rolling press device it to reduce or increase the arch, then re-tempered afterwards???? Quote Link to comment Share on other sites More sharing options...

You are right, but if you heat the metal until it starts to change colour, not hot enough to change to red but when it starts to get a tinge of purple or blue, then if you let it cool in the air it normalises the metal, which will be making it softer and a lot more saggy than when they came out of factory. I'm not sure what cooling rates springs require after heating, but after any heating you should probably reheat to red hot and quench in oil or water. or else they might sag like crazy when you load them up.

Archers springs it Rotorua reset springs with no heat whatsoever. I worked at Auld & Voss in Palmy for a few years before it closed down. We always warmed the leaves up slightly to prevent snapping them when re-forming in a press Quote Link to comment Share on other sites More sharing options...
