Step 1: The Base

You'll first make the base.

Step 2: Motor and Gearing Part 1

Now it's time for motor and gearing. You'll may be able to modify it so that it uses a different motor, but I don't think that that works as the motor needs quite a lot of power.

Step 3: Motor and Gearing Part 2

Next part of motor and gearing.

Step 4: Motor and Gearing Part 3

This is the third and last part of motor and gearing!

Step 5: The Push-track

Now you'r making the small track piece where the balls are pushed allong.

Step 6: The Pump

Now you'll be making the actual pump.

Step 7: The Turning Up

This is where the balls go from horizontal movement to vertical movement.

Step 8: The Shaft

Now your making the ball shaft.

Step 9: The Top

It's time to make the top!

Step 10: Your Finished

You just have to add six balls into the shaft and then your finished!
