    Hey guys, not just any steel will temper and make springs, you need a high carbon content for the best springs. The raw spring stock can be purchased fro Brownells gun smithing site or catelog. For camera back type springs, you can use a propane torch for a heat source. Simply keep it moving while bringing up to non magnetic red, then bend and cool slowly, or quench it in ambient temp. water then reheat to straw to temper for a working spring.
    Cooling slowly will be the same as annealing, quinching will make it too hard
    and will have to be slightly tempered. Do it in a shaded area (out of bright sun light) where you can see the color changes of the steel.

    Brownells spring stock is soft enough to file or cut with a jewlers or hack saw.

    Spring this

    On the 4x5 camera I built, the plans called for using the spring metal off the back of the rubber on windshield wipers. I found an old set at the gas station and they were springy and easily bent into shape. However the tight tolerances seemed out of my league for the groundglass and back, so I ended up stealing the grafloc back off a press camera and away I went.

    Contact me if you want more info.

    Has anyone tried piano wire for the springs? I was thinking of using them but still trying to find a source.

    Canuck,
    The local hobby emporium should have music wire in 3' lengths x whatever diameter you want up to about 1/8".

    Yup. Used piano wire on my last camera and it worked MUCH better than flat springs but you have to run the GG frame in some kind of guide because the round wire springs will bend in any direction.

    Hi Eric: What plans are you referring to? I thought I had all the camera plans ever published. I might have missed one.

    Thanks
