    In Bill Smith’s book on construction of a skeletal clock, he states the click spring is made out of 1/16 brass sheet. Lay it out and cut it down. Then bend into the final shape that has a 1 9/16 radius. No details on how to do that.

    Just how does one go about bending it into a curve with such a radius? I tried light hammer strokes along the edge while clamped into a vise, which does bend it, but the bending is not continuous so it ends up with a bunch of humps.

    Ideas?

    It seems like some kind of roller mechanism even if home-made might do the job.

    I like to bend it around a form. A socket set will give you a variety of different diameters to work with. Just clamp the socket in the bench vise to hold it while you bend the click. It will spring back some, so a somewhat smaller radius than the final dimension may be needed. I don't think the exact radius is critical. Just give it a curve that looks good and contacts the click in the correct place.

    Which clock are you building?

    Thanks for the replies and ideas, will give them a try this weekend. Maybe if I cut the stock thinner it will be easier.

    I’ve been working on Bill’s scroll skeleton clock, what seems like forever. I have to leave the project for months at a time and even once for an entire year. The click is something I forgot to do, but when complete, onto the dial and motion works, and final polishing.

    Not sure what I’m going to do about the dial as I only have a mini lathe. I do have a mini mill and thinking of offsetting the material while mounted on a rotary table.

    Thinking about your clock Allan for my next clock.
