This lift is much better than the double helix lift, because you can make it very high, since the tower in the middle is much stronger than a double helix. It's more smooth, and more fun to watch, too. :-) It does use a lot of pieces though.
This is different than the original used in Cataclysm. It uses much less pieces. If you have enough, you can make it as big and piece-consuming as you want.
Here is a video of the inverted double helix lift in action!
Note: This lift does not work with newer Knex balls (balls from Motorized Madness, Big Air Ball Tower, etc.) because they are too big.

No, ok, probally because the motor doesn't have to pull so much up?
Great job! I'm putting it on my newest ball machine!
I built the alternator lift and this one looks MUCH easy-er 9 steps is alot less that 41!
