I know I don't have time to build my machine in the real world just yet, but I put it together in the CAD world first. The idea is to have a lot of simple moving parts that create an overall, fluid look. I have designed it to be operated by hand but you could just as easily run it with a motor, miniature wind mill (for the greenies) or better yet a hamster wheel.
Practically speaking, you could also use the machine for student demonstration to illustrate the basic sine wave or the difference between wave and particle movement. Mostly it is just meant to look interesting.
Thanks for checking out my first Instructable.

Material: (Use whatever you want, this is just what I would use)
-One sheet of foam board for the base
-1/4 in balsa wood sheet for the Cams
-1/8 in base or ply wood for the Levers and uprights
- 1/4 in dowel
- Straw just big enough to slide over the dowel
- Light weight thread
- 25 heavy glass beads or fishing sinkers
- Glue
- Drill x (Drill Press) & Assorted bits
- Small Triangle File
- Hobby Knife and Sand Paper
- Band or Scroll Saw (CNC Router or Laser if you’re lucky)
- In the absence of the CNC machine, lots of patience

Step 1: The Easy Part...

...if you have the CNC machine. If not put on some good music and get comfortable in front of your band saw. Attached is a PDF of the main parts and the quantities needed. You can measure them out on your material or just print the PDF off at a 1 to 1 scale, then use it as a template. Also attached is the Sketchup file. Well... start cutting. When I make mine I think I might try to find a hole saw that is the right size to create the cams. This will give a nice consistent circle with a definite center hole to measure off of.
Time lapse to several days later......
Now get up, stretch, blow the sawdust out of your nose, shake it out of your hair and go create an Instructable to win the CNC Laser machine.


<p>i can't understand how you made the cam worm since the hole of the cams through which the axel passes is in the same place! :/</p>
<p>If you look closely, you'll notice there are three holes. Two smaller ones, and a larger one. The larger one is the one through which the axle passes. The two smaller ones are used to line the gears up in a worm formation. When you assemble the wheels, make sure only one of the holes lines up. This will offset every wheel by 30 degrees.</p>
I made one of these for my science class, it only had 6 (maybe 5?) levers and was very rudimentary, but it did the job and got me an A. Nice writeup, the 3d really captures the process well.
akward i am makeing one fore science class 2
Looks beautiful!! <br>
pretty sweet!
Very detailed, well made instructable. I actually just programmed a simulation similar to this; I'm positively fascinated by this simple contraption!
If you have Google Sketchup or are willing to download it for free from google , I just added the full 3-D file to the first step. Feel free to play with it.
Well, done...<br>What cad program did you use?<br><br>It would be fun to make/build!
I used Google Sketchup. It is a great program considering it is free. A quick google search can show you were to down load the program. <br>
for the autodesk contest, you actually have to make it
