You want the wheels to spin but not wiggle or be loose on the rail.
By spin do you mean you start them turning and they will continue to spin on their own, or just that they turn with minimal force? Seems tricky to get them tight enough to not wobble and still spin freely enough to continue turning on their own once started.
