Step 1: The Center Frame

This is where the lift will be located.

Step 2: The Wheel Side

This side will hold the wheel later on.

Step 3: The Other Side

This side will hold the other stuff.

Step 4: The Top Gear

This part will support the chain.

Step 5: Mini Thisorthat

This part decides where the ball goes.

Step 6: The Micro Ramp

This leads to the Wheel.

Step 7: The Wheel

This part spins. Build, take out a blue rod, then put in the Wheel. Replace blue rod.

Step 8: The Ramps

These two make the ball drop.

Step 9: The Chain

This part has 35 Black chain links.

Step 10: Usage

Fix this part.

Add ball, Turn on.

     dont know to build this or immueble??? i know il build both!!

    If he made it into a larger version it would defeat the point of it being small which is what it is meant to be. If you want to build a large ball machine, find an Instructable that actually shows how to build a large ball machine.

    I built this ball machine a few days ago. Every day I've added at least one more different path/element. My final addition, which I'm working on now, is a double helix lift. The basis, obviously, is the Project BOX Ball Machine.
