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.

This part has 35 Black chain links.

Step 10: Usage

Fix this part.

Add ball, Turn on.

    ebay or knex.com but get the standerd from knex those are the one you are looking for not the other ones the other ones are small

     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.

    Do u think u could take better quality pictures? 4 me it was kinda hard 2 understand at certain parts...
