"Dick and Smithy in the Workshop" to the rescue!
In the past I've bored-out quite a few old potentiometer bushes for this sort of thing, and yes, knitting-needles are a good cheap source of suitably-sized shafting.
Another tip: a short length of the stiff Nylon tube used in industrial pneumatics/robotics makes a good spindle-coupler: heat it in boiling water to soften it and you can then force-fit 1/4-inch/6mm spindles into the ends. This is a good way to deal with diameter-mismatches when you've got a mix of 1/4-inch/6.3mm and 6mm - something that doesn't always work out to be smooth-running when you use solid couplers.
