We used nuts and bolts, with various amounts of washers, at up to three points around each wheel. And a cover over the whole shooter assembly.

My apologies, I meant centrifugal.

I don't know how this works against us though.

Considering our weights are on the very outer edge of the plastic hub, pushing them outward away from rotation keeps them more solidly in place.
