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.
Note: You can also make this lift with one strand of tubing instead of two. This way you'll use less orange-tabbed connectors and tubing. Go to step 2 for details.
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.
Step 1: Parts Count
- dark gray-20
- light gray-3
- tan clip-3
- blue spacer-16
- silver spacer-7
- battery-powered motor-1
- strands of tubing-2: one 6 feet 3.5 inches long (191.77 cm), and the other 6 feet 4 inches long (193.04 cm). You don't have to cut the tubing, but it is recommended that you do. Go to Step 7 for details.
And you'll also need original Knex balls.
If you have enough pieces, then let's get building!
