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.

<p>Could I possibly make this longer and higher? </p>
<p>Yeah, I'm not sure what the limitations are though. I built one that was 5 stairs and it worked fine, and I think there have been 6-stair ones that work well too. </p>
Hmm ok thanks for the reply.
<p>I made it ..... again!!!!! like your cat it always gets in the picture!!!!!!!!!!!!!!!</p>

<p>I did it!!!! will show a picture!</p>
<p>ok! thanks! I have an old battery pack motor that runs ok but it squeals a lot. Glad to hear it will work!!!!</p>
Is this part necessary in step 1
No, that's just the piece counting step, so you don't have to build anything yet.
I built it worth pure genius
Nice, thanks for building!
COOOOOoooool! Awesome! You've built a great instructable!
In step 2 pic4, whats the black thing underneath the black snowflake connector? (2nd from left) <br>
I honestly had my doubts about this but I built it and it worked. Very nice job on the design.
Thanks!
Thats cool! 5* you deserve it! =D
Thanks! :-)
No Problem, this is ingenious! =D
<em>what if u dont have have the red motor i have just a blue motor can i still run it </em>
Yes, you'll just have to modify the motor section a bit.
My motor (Green one) Doesn't fit :-(
Isn't that motor too weak?
Ive built it now, Works just as fast as his
It should fit in a green rod space. Just change the orange connectors on the side to white, and take out the blue spacers.
Ok
1) stop it your awesomeness is going to kill me <br>2) sweet cat
Haha, thanks!
=D
Finished!<br><br>Its AMAZING
Yay! If you post a picture, I'll put it on the last step.
If I can find my card reader I will
Iv done what you see for the green motor is this right (Right to left)<br><br>Tanclip with clip in a small cog, white connector,motor,white connector,2 blue spacers, blue clip on the end.<br><br><br>And are the axel and motor actually connected?<br><br>Mine aren't
Maybe you should post a picture. :-)
Ok Ill do it tomorrow because my computer is being really slow right now.
Gonna start building and when I run out of blue spacers Ill just wait for the ones I ordered so I can finish it.
