I have one of those operating freight stations from the 80's where the base vibrates and the guys move around with their carts. The guys don't move too fast at all, and at some points, they need help. I've already increased the power to the accessory, and it helps very little. I noticed that the bottoms of the carts have rubber inserts. It seems to me that these are counter productive. Do you think it'd help if I put felt squares on the bottom of these things?
