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

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

MICRO K'NEX Transition Rod Red, you can better use this rod, without damaging pieces.

Wow, cool, thanks a lot!
Keep in mind that you could probably make it higher but idk how the motor would react :P
That's right but I don't really nead to make it higher, it's not necessary.
BTW I have two 12v motors but only one adapter that I allready used for the parallel arm lift, I'll have to buy a second :)
Sorunome (author)  sandroknexmaster2 years ago
why do you use two motors on the parallel arm lift :P
No I mean I have two 12v motors, but only one working adapter.
One of those motors and the adapter did I allready use for th parallel arm lift, so I have to buy a second adapter for the motor in the pump lift. =)
Sorunome (author)  sandroknexmaster2 years ago
Oh, gotcha, i have 3 12V motors and two adapters, one of the adapters the polarity is wrong so it'll go backwards, lol
Haha lol :)
Nicej ob!

Very clever machine. Did you come up with the concept or is a borrowed idea?
Sorunome (author)  Oblivitus3 years ago
Thanks! And I came up with it all alone :)
Excellent. 4 stars (I reserve 5 stars for things that shoot fire and puke rainbows, lol).
Sorunome (author)  Oblivitus3 years ago

Very cool idea!
