New challange! Old problem!

[G.T.]

Hi Rich, actually it broke in two spots, and the shorter sister spring is cracked at/near the attach /anchor end? I thought about just making a single leaf spiral spring, but I've not yet figured out the reason behind the stiffener spring about half the length of the main coil spring?? I could grind off the rivet, and shorten it up some and try that.. but until I get more springs as usable parts or samples, I hate to alter this one as I might need to submit it to a spring company to get any further along on this??....... Best to all, til...lat'r....GT.....

Also, I have no idea what preload is required to make it function correctly.. probably put a fish scale on the end of the lever on a good unit to see?....GT
Also, also squared... I can get spring steel coils close enough to make the springs..... but still need to understand design and demands??
