Okay, this first picture is before both wheels are up, but the light was just too cool, not to post it.
The 14 foot wooden wheel is off its track a bit here and leaning back quite a bit. I had to stabilize it temporarily at the top by tying off some ropes. Later I would use a couple of car jacks to get it back in place.
Each wheel is 400 pounds and made up of 8 pieces. The 50 pound elements were harder to move around and assemble than I expected. At first I tried to set up some pulleys to help get them in place, but by the second wheel I just grunted and did it all by hand. It ends up it was a lot faster that way.
