Ah, yes, using two wheels on each side to accelerate the balls will provide
better traction. I was envisioning the wheel as a direct tangent to the
sphere ...
I can see the mass problem, and will include flywheels on these as well.
Thanks!

Exactly, Hot wheels uses the idea as well as those machines that shoot
tennis or baseballs for practice. The baseball ones use a boat trailler
wheel
driven by an electric motor. Just make sure the spinning wheel has
a large mass to keep its speed up when the ball comes in contact.

I like the idea of using wheels to accelerate the balls. I believe when I
was a kid one of my friends had a Hot Wheels car wash or somethingorother
that used the same concept to move the little cars around a Hot Wheels
track. Certainly worth trying. I think the balls are so light, though, that
using several sets of wheels might be pointless--it's not like having to
accelerate a large mass.
Thanks!
