Large Wheel Lathe
Most (if not all) the parts for a wooden large wheel (4 foot diameter) treadle-powered lathe. Not all parts shown in picture, but I believe all the necessary parts are included -- at worst you'd have to make a couple small parts. The treadle is about 6 feet wide.
This will have to be shipped freight at your cost (FOB), or picked up near Seattle. A very cool demonstration lathe.
