Hello Gentlemen
My question is I would like to know what I need and how to do it to check the tension of a coil spring for the proper strength. This is my dilemma have just ordered a pair of firing pin springs for a gun I use for bird season. I suspect that one of the springs is weak which is unusual but never the less I am going to try that first. What I want to know is the compression strength of the new spring and then try to bring the old one up to that strength, buy heating it red then putting it in hot lead and holding it then quenching it in oil. I know how to do it with flat springs to put them in a vice and close the vice to see if it springs backs or breaks but I don't know how to test a coil spring. The only thing I can figure is that the thickness of the steel to make the spring decides the strength of that spring. What are your thoughts on this. Any help is greatly appreciated.
