You'll first make the base.
 
MICRO K'NEX Transition Rod Red, you can better use this rod, without damaging pieces.

Very nice lift, I've built it and it works great!
I'll definitely use it in my next ball machine.

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. =)

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 :)

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).
