Introduction: Knex Stair Lift
I finally decided to post my stair lift. It's similar to the stair lift I used in Wipe Out, except for a few modifications. The steps sort of work like pistons, going up and down on rods of different length. Each rod is a green rod higher than the one before it. This one has an improved design since the last one, like better platforms and an enter and exit track. I also made it more reliable.
This lift also works with the newer balls.

Step 1: Parts List
Before you begin building, you'll want to gather all of these pieces:
dark gray- 57
(metallic) blue clip-1
battery powered motor-1
balls-at least 1
If you have all these parts, then on to the next step!
Step 2: The Axle and Motor
In this step you'll build the axle that lifts the stairs up and down and put the motor on. The axle is part A, and the motor is part B. Don't forget any spacers!
Step 3: The Tower, Side 1
This is one side of the tower. You'll find that there's a pattern on the tower. Not much more to say, but pay close attention to the pictures.
Step 4: The Tower, Side 2
This is the second side of the tower.
Step 5: Combining Steps 2-4
In this step you'll assemble what you have built so far. Make sure to connect everything when putting the towers together.
Step 6: The Motor Section and Entrance Track
After you're done building the motor section and entrance track, you'll attach them to the model.
Step 7: The Steps
Now you finally get to build what the stair lift is all about. You'll have to build four steps.
Step 8: The Exit Track
This is the easiest step of this Instructable.
Step 9: Adding Steps 7 and 8
You're almost finished! Just add the steps and exit track to the model. Make sure the steps slide on the yellow rods.
Step 10: Done!
Hooray, you finished the stair lift! Now put the balls in, turn the motor on, and watch the balls go up.
