The bucket was a very simple toy to build. It's also one of the few that's completely clear about how it is put together. The angle is such that you can see the dowel going through the body.
You can also see that reality fell a little short of the conception. In the drawing, the edges of the dowels are flush with the collars. Not so in real life. Still, it's a minor quibble -- like the name of this thing. This looks more like a basket than a bucket. But that's just my opinion.
