Looking for project parts Answered

I need to attach an arm to the end of a stepper motor shaft that I will then use to rock a babies car seat. Finding an arm (or horn) is turning out to be more difficult than I thought. Does anyone know a place to pick up stuff like that. The shaft is 5mm Thanks

You might be better with a windscreen-wiper mechanism?
You might have to make one: drill a 5mm hole in a piece of bar, drill a smaller hole at 90o and hacksaw through to the 5mm. Clamp to the motor shaft with a nut & bolt.
