Well, I thought it was finished, but it wasn't. The tops were heavy to lift. And keeping them lifted meant lifting them totally up and over to rest on the fence. Which annoyed me.
And then I had a totally wicked idea. Counterweights...
The tops took 17 pounds of upward pressure to lift before (I weighed the lifting pressure with a fishing scale). So I screwed 2"x4"x6' boards to the tops and added some 6"x6"x53" posts left over from building the new decks (I save scraps and this is why).
Here are the bins now.
