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.

[Snosageman99]

In step 2 pic4, whats the black thing underneath the black snowflake connector? (2nd from left)

[hi452]

I honestly had my doubts about this but I built it and it worked. Very nice job on the design.

[Shadowman39]

Thanks!

[albydesign]

Thats cool! 5* you deserve it! =D

[Shadowman39]

Thanks! :-)

[albydesign]

No Problem, this is ingenious! =D

[jman1356]

what if u dont have have the red motor i have just a blue motor can i still run it

[Shadowman39]

Yes, you'll just have to modify the motor section a bit.

[MegaMetal8]

My motor (Green one) Doesn't fit :-(

[Randomguy65]

Isn't that motor too weak?

[MegaMetal8]

Ive built it now, Works just as fast as his

[Shadowman39]

It should fit in a green rod space. Just change the orange connectors on the side to white, and take out the blue spacers.

[MegaMetal8]

Ok

[aleceatsfood]

1) stop it your awesomeness is going to kill me
2) sweet cat

[Shadowman39]

Haha, thanks!

[aleceatsfood]

=D

[MegaMetal8]

Finished!

Its AMAZING

[Shadowman39]

Yay! If you post a picture, I'll put it on the last step.

[MegaMetal8]

If I can find my card reader I will

[MegaMetal8]

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]

Maybe you should post a picture. :-)

[MegaMetal8]

Ok Ill do it tomorrow because my computer is being really slow right now.

[MegaMetal8]

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]

Be sure to take a picture of it, so I can post it to the last step!

[MegaMetal8]

I don't know how to get the motor in because mine is the green one, it doesn't fit.

[Shadowman39]

What gets in the way, the crankshaft rod? (which is the one connected to the red gear).

[MegaMetal8]

Ill just do what you said in that other comment :p

[MegaMetal8]

Are all the tan clips really essential?

Please reply ASAP

[Shadowman39]

You can leave the tan clips on the axle/crankshaft out.

[MegaMetal8]

Replace them with blue clips?

[Shadowman39]

If you want to.

[MegaMetal8]

Ok

[MegaMetal8]

I have 13 : /

[Shadowman39]

13 what?

[MegaMetal8]

Tan Clips

[MegaMetal8]

Awww was gonna build but don't have enough spacers :-(

[Shadowman39]

That's too bad. :-( I wonder if it would still work without some of the spacers.
