Could you not flatten off a side of the shaft (or cut a keyway in) and then get a wheel hub that uses a grub screw to hold the hub onto the shaft (like this for example?)

Ah I think I see. I can imagine fixing the wheels securely is a major task for many robots. Certainly using drill chucks is easier at this stage. I was looking at the drill motor mounts on the forum and if I did use those I would need to find another way. For now I hope this next set of wheels have 8mm or 10mm hubs (there seems to be some confusion on the website). Either way some 80-100mm bolts, suitable washers and nuts should give me what I need to let me get it ready to whip around the garden patio.
