Introduction: Compact Separator: a K'nex Ball Machine Separator

Here are the instructions for the new separator on our K'nex ball machine Impossible. This separator isn't all our idea. Thibault Art originally came up with this idea on his ball machine Route 66 at 7:30, so all credit goes to him. We just made our own version and are making instructions for it. Have fun!

Step 2: The Frame

The beginning is a good place to start. Let's take the frame for instance! It's what holds the whole thing together!

Step 3: The Separator Module.

This is the part that actually does the separating!

Step 4: The Exits

The exits for the separator. Since it separates 2 paths, there are 2 exits.

Step 5: Done!

You now have your own Compact Separator to implement to your k'nex ball machine! If you built this and you want to let us know, feel free to post a picture of it, and we will add it to this step!

    it separates out balls for a knex ball machine. The video should tell you more about how it works/what it does. :)
