Knex Elevator Free Fall Lift

Hello everybody.
     I got the inspiration for this lift after seeing Alocke's ball machine Tartarus. As you can guess by the name, when the car gets up to the top it suddenly free falls. This is do to the special gearing mechanism. I modified a medium knex gear by taking off some of the teeth leaving only 17 left.  When the teeth of the medium gear catch hold of the small gear (see picture 10) it turns the shaft which is connect to a wheel-like device which winds in the string (or chain) connect to the car thus pulling the car up. When the car gets up to the top there are no more teeth turning the blue gear thus making the car fall. Enjoy the video.

I've built it and it works great. Instead of cutting of the teeth of a yellow gear, I used an orange gear. (I guess you know it)
I'll use it in my next ball machine
Thanks for this awesome lift!

[KneXtreme]

Awesome!
Can't wait to see your ball machine!
Your welcome.

[sandroknexmaster]

Ok but you will have to wait veeeery long, probably more then 2 months.

[collinjo12]

This IS pretty cool! But the reason you didn't use an orange gear is because you probably don't have the drop n swing right?

[KneXtreme]

Thanks. I have the orange gear, but I didn't use it because I broke it testing the mechanism.

[knexgunbuilder217]

does this require chain links

[KneXtreme]

No, but you could use chain links instead of rope.

[jameshond]

i have the orange gear can i use this it hase 16 teeths

[KneXtreme]

Yes.

[jameshond]

oke thanks

[jameshond]

Thanks

I'm sorry to ruin the fun but the mechanism is not original. A similar mechanism is on a knex amusement park series on a free fall ride that includes an orange gear but great job making it into a lift!

[KneXtreme]

Thanks, but what amusement park ride was it on?

[Sorunome]

Nice one! :)

[KneXtreme]

Thank you for my 400th comment.

[Sorunome]

Haha, cool! :D

Now this is a fantastic bit of engineering. Very original design, I'd love to see it in a working machine.

Best thing on instructables for months :-)

[KneXtreme]

Thanks. I'm planning on using it in my next ball machine.

[Purple Waffles]

I think I'mma try and use this in my upcoming ball machine.

[KneXtreme]

Cool! It would be nice to see it in a working machine.

Knextreme, what a wonderfull lift again, I love your work, thanx for sharing!

[KneXtreme]

Your welcome. I'm glad you like it :)

[knexpert#10829476]

Thank god that I don't have to modify that yellow gear because knex.com has orange gears that are just like the modified gear for those who don't know.

[Alocke]

I'm glad I could inspire some new ideas :)

@Sathothy:
I live in Holland aswell and buy my parts @marktplaats. Give it a look, theres plenty for sale ;)

[sathothy]

Yep, I treid doing that but my parents wont allow me to bidd on stuff that are over an 15 KM range. But I still trei. I never won(Is that how you say it?) something. But I'm only bussy doing that for an couple of months(like three).
Thanks for the help to!

Ducht:
Ja, dat doe ik al, maar mijn ouders willen niet dat ik op dingen bied die buiten een gebied van 15 KM zijn, maar ik probeer het nog wel . Ik heb nog nooit iets ''gewonnen''(Is dat hoe je het zegt?). Maar ik ook nog maar een paar maanden(ong. 3) bezig met dat doen.
Toch nog bedankt!

[Kipcorn]

Hi Sathoty,
They can send it to you?

Je kan het toch laten opsturen? Kost je 6,75 tot 10kg. Scheelt je een hoop tijd en geld voor benzine. Is bij mij nog nooit fout gegaan. Succes!

[sathothy]

Weet ik. Maar mijn ouders vertrouwen dat niet. Dus ze willen het ophalen.

[Shadowman39]

This is a cool idea! To make it taller, the gear would have to be different though right? (the one that's modified).

[KneXtreme]

Video is up.

[Shadowman39]

Now I know what the red connector wheel is for. :-P

[KneXtreme]

Thanks. Yes, the gear would have to be different. You could also make it taller by taking some teeth off a large gear and using that instead, but you'll have to rearrange the gearing mechanism.

[imans314]

Cool, can't wait to see the video

[KneXtreme]

Video is up.

[imans314]

Thanx, I love it.

[sathothy]

Looks awesome! Do you have an video of it working?

[KneXtreme]

Video is up.

[KneXtreme]

Yes I do but my computer is running slow. I'll try to upload it tomorrow.
