Here are the instructions for the pump lift featured in Catastropha! If you have any questions then feel free to ask! Be sure to read all the image ...
You'll first make the base.
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 ...
Next part of motor and gearing.
This is the third and last part of motor and gearing!
Now you'r making the small track piece where the balls are pushed allong.
Now you'll be making the actual pump.
This is where the balls go from horizontal movement to vertical movement.
Now your making the ball shaft.
It's time to make the top!
You just have to add six balls into the shaft and then your finished!
