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.

EDIT:  This Instructable reached 4.13* within a day after posting.


I hope you like it!

Step 1: Parts List

Before you begin building, you'll want to gather all of these pieces:

Rods:  296

Connectors:  261
dark gray- 57
light gray-20

Other:  122
blue spacer-47
silver spacer-43
Y clip-5
tan clip-23
(metallic) blue clip-1
red gear-1
blue gear-1
battery powered motor-1
balls-at least 1

Total:  679

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 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

Picture of 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.

Yes, you'll just have to modify it a bit.

No, that's just the piece counting step, so you don't have to build anything yet.

My motor (Green one) Doesn't fit :-(
Isn't that motor too weak?
Ive built it now, Works just as fast as his
Shadowman39 (author)  MegaMetal83 years ago
It should fit in a green rod space. Just change the orange connectors on the side to white, and take out the blue spacers.
1) stop it your awesomeness is going to kill me
2) sweet cat

If I can find my card reader I will

Iv done what you see for the green motor is this right (Right to left)

Tanclip with clip in a small cog, white connector,motor,white connector,2 blue spacers, blue clip on the end.

And are the axel and motor actually connected?

Mine aren't
Shadowman39 (author)  MegaMetal83 years ago
Maybe you should post a picture. :-)
Ok Ill do it tomorrow because my computer is being really slow right now.
MegaMetal83 years ago
Gonna start building and when I run out of blue spacers Ill just wait for the ones I ordered so I can finish it.
Shadowman39 (author)  MegaMetal83 years ago
Be sure to take a picture of it, so I can post it to the last step!
I don't know how to get the motor in because mine is the green one, it doesn't fit.
Shadowman39 (author)  MegaMetal83 years ago
What gets in the way, the crankshaft rod? (which is the one connected to the red gear).
Ill just do what you said in that other comment :p
MegaMetal83 years ago
Are all the tan clips really essential?
