• Mrs Linc - "When are you going to stop messing around with bikes and sort out something nice to brighten up the living room?"

    I'm not sure this is quite what she had in mind or that it counts as stopping messing around with bikes but I'm quite pleased with it nevertheless.

    So, I present the crank clock

    The numbers round the chain show the hour at the top of the chain while the black hand on the jockey wheel shows the minutes. Top sprocket rotates once per hour fixed to the hour spindle of a cheap clock mechanism.

    Vintage Stronglight crankset, 12t sprockets, 12t jockey wheel, 144 link chain, set of bearings installed in the crank spindle hole and a high torque quartz clock mechanism at the back.
