093. Power Hammer
This toy proved very difficult to build. In the illustration, there's plenty of room between the top dowel and the one holding the cube in the cross-brace. In reality, there was no room at all, regardless of how far forward I tipped the 5-hole girders.
You may also notice that the 3-hole girder is secured to the crank at one end, rather than the middle as depicted. There's a dowel that runs through the assembly that joins it to the base. The length of it blocked the opening I was supposed to use. To position the girder so it touched the axle, I had to run the dowel through an end hole, rather than the middle one.
