Level 45 "Tug of War"

I feel like an idiot, but I can't figure this out. It's got the two weights, two bearings, and the conveyor belt going the wrong direction. I have tried placing the bearing under the weight, which gets the weight some distance along, but not far enough.

Supposely the idea is to make the steel balls help the weigh roll though the conveyor belt...But i tried one thousand times and I never get it right

I am stuck there too. It moves it some but not enough. Anyone out there figured it out?

You need to put the steel ball underneath the 1st weight (the one on the incline). It takes a couple times to get the position just right (keep moving the ball ever so slightly until it works), but once it's in the right place the 1st weight will slide down into the box and the rest will follow.
