    I bought a couple of tall case great wheels, just to play with.

    They both need click springs.

    I'm trying to make those springs out of .40 main spring i had lying around.

    I could just buy the replacements at timesavers but thought it would be fun.

    Reasonable? asking for trouble?

    Just to clarify. Are you talking 0.40 mm, and if so you can make them out of any spring steel you have on hand.

    Sounds like fun.

    Are you going to do anything with them after you get the clicks to work?

    The click springs on mine are all brass.

    Smike, steel banding that is used to secure stuff to skids etc makes a nice source of spring steel. It comes in 0.015" and 0.020" and thicker. I asked my local industrial supply guy to save me a couple of feet. Nice stuff and for free.

    i just bought 'em because there's something about great wheels that makes me happy... not sure if i'm going to end up doing anything with them other than CCEUs (continuing clock education units).

    yes, i'm talking about using .40 mm mainspring, from a broken one i took out of a movement.

    i've already got the shapes roughed out and just need to hand file to make the little projections that stick/secure into the great wheel itself... worst case scenario i screw it up and have to start over... but i have plenty of stock to work with. :cool:

    cool... may have some in the garage somewhere in the 'you should probably clean this up sometime' pile.

    i'll see how the main spring works...

    Your tip is a day late & a dollar short. I threw out metal strapping 3 times in the last few weeks. I'll have more and save myself some next time.
