    Hi,

    Does anybody know a place that sells motor crank arms (they must be common in robotics?). I have some DC motors with 9mm flat keyed shafts.

    I have made my own very crude cranks from flat iron stock using a dremel to create a keyed hole to grip the motor shaft but the fit is very poor.

    I've attached a picture of a the kind of thing I'm looking for.

    Cheers,

    Matt
