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

I know.. ;) but someone
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. =)
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 :)

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
