Since lots of people like this lift, I decided I would make an Instructable of it. This is the first Knex spiral lift that has two spirals instead of one. This allows twice as many balls to be lifted up into the tower than the original spiral lift. It's also the first to use tubing for the spiral, which makes it perfectly round.
This lift is a copy of the one I used in Wipe Out, except it's shorter, it uses a battery-powered motor instead of an electric one, and the tracks going in and out of the tower are different. It can be built with only one spiral, but the bottom where the balls come in might have to be changed. A cool thing about this lift is that the platform and shaft can be on any side of the tower because the double helix is in the center. It's also easy to modify.
This is my first Instructable, and it took me a long time to make because the pictures took a very long time to upload.
Here's all the pieces you'll need to build the double helix lift:
Rods:
Green-104
White-54
Blue-43
Yellow-39
Red-56
Tan (rigid)-1
Gray-10
Total rods:307
Connectors:
Dark Gray-54
Light Gray-0
Orange-18
Red-21
Green-8
Yellow-23
White-26
Blue 3D-41
Purple 3D-71
Total connectors:262
Other:
RC Tubing- 2 pieces, each 3 feet, 5 1/2 inches long
Battery-Powered Motor-1
Black Y Clip-17
Tan Clip-10
Blue Spacer-40
Silver Spacer-28
Small Tan (or Blue) Gear-4
Red Gear-1
Large Yellow Gear-1
RC Tubing Splicer-2
Total other:106
Grand Total: 675 pieces
If you have all these pieces, let's get building!
I hope you like it!

To start out, let's build the core of the double helix. The red rods that help make it sturdy are in a repeating pattern all the way up. The tubing will go on it in the next step.

Shadowman could you make this really tall like 8 red boxes or so? Also please check me out on youtube @ Youtube.com/user/Gnmar2723.

Shadowman39 (author)
in reply to Apr 21, 2012. 3:00 PMReplyIt probably wouldn't work if you made it that tall, since the helix wouldn't be strong enough. And I've seen your Youtube channel before, you have some good ball machines. :-)

in reply to Dec 22, 2010. 2:48 PMReplyYou could try to hook up the motor to the axle of the double helix, without using any gears. But the helix will spin around much faster.
