Ball-end mills are neither expensive nor rare. We have a set.

Yes indeedy, but it's probably more dangerous that I'd be willing to let a kid do. You must use a template for the router to follow, there's little chance of really controlling it freehand. We cut the triangles into the 3/16" aluminum we used in our rookie year for our robot cart (the pattern matched the .090 'armor' on the robot). An experienced parent did that for us. Me, I thought he was crazy, but dang if he didn't do it nice and neat.


As for the wheel, I'd probably turn it on a lathe before I brought it to the mill.
