Introducing the Do-nothing Machine. As the name suggest it does absolutely positively nothing useful. Sure it may entertain some people for a few minutes, last about an hour on me, but it still does nothing.
This is a fairly easy machine to build. Takes a few hours to cut out the pieces and a few more to glue together and let dry. I have chosen a simple layered design so that those without a router or other means of cutting a T slot could easily complete this project.
I used Pro/Engineer 4.0, a CAD program, to draw up my design and to determine the dimensions. The drawings are provided as a .PDF at this step for download. They will also be provided as pictures in the next step.

- 1/4 inch plywood. I found some cabinet grade scraps in my shop. Any type will do it just depends on how well you wish the finish to look.
- 4X 1/8 inch washers
- 2X 1/8 inch by 3/4 inch long pop rivets
- 1/2 inch by 1/8 inch steel, brass or other strong material to make a lever.
The pictures provided are exactly the same as those in the .PDF
If you find any of the drawings unclear please point that out to me so that I may correct them.

Without reading your instructable at all I will give the following tip.. If you lightly sand the pieces in the direction of the travel of the shuttles. Then you shouldnt need lube. Also after about an hour of use mine is now much easier to turn. Just needs to bed in a little I guess.
Mart.
Wikipedia confirms that, and they are never wrong.
