Introduction: Knex Tubeless Helix Lift
This is a variation of the helix lift that uses flexirods instead of tubes.
Whenever I build it I find that it only works with one ball, and you can't hand-crank it or else it will get stuck.
If you have tubes, I would recommend you rather build a version with tubes.
Step 1: Frame
Construct a frame made of red rods.
At the bottom of the frame, place some white connects to hold the helix.
Up the side of the frame, make a pattern that the ball wont go through.
You also might want to put grey rods everywhere to make it more stable.
Step 2: Rail
Add a gaurd-rail that the ball will push against.
Step 3: Helix
Most of this pattern keeps the helix rigid. Make sure that it is attached to a rod such that when the rod spins, the whole helix spins.
Step 4: Adding the Helix
Slide the helix into the base so it can spin.
Add a motor at the top to hold and run the helix.
