Introduction: Spinning Freefall Lift, a Knex Ball Machine Lift

Hi everyone

Here the instructions for the new lift in my knex ball machine Dragonfire.
I have changed the lift a little bit, more exactly the entrance.
In the vid of Dragonfire, you can see that there are several balls rolling to the arm at the same time, but the arm can lift only one ball at time, that's why there is an extra path (path 4).
In this new version there is another way to bring the ball to the entrance of the arm.
Now only one ball can roll to the arm, and not two (or more) at the same time.
Much better!

If something is not clear enough, let me know!

PS: Thanks to KneXtreme for the name of this lift!

Step 1: Piece List

First, you have to count the pieces.
All the pieces are named by the original color.

RODS:
green 67
white 44
blue 81
yellow 26
red 67
grey 44

CONNECTORS:
dark-grey 20
light-grey 2
orange 10
red 14
green 10
yellow 69
white 11
purple 122
blue 12

OTHER PARTS:
tan clip 8
blue clip 5
Y-clip 16
blue spacer 22
silver spacer 25
small blue gear 2 
medium red gear 2
medium yellow gear 1
large yellow gear 1
blue* knex motor 1

TOTAL: 682

And off course you'll need some knex balls!

*I used a new knex motor. They exist in different colors.
Use the blue one, that one has the best speed.
You can't use a green one cause it turns to fast.

Step 2: Entrance

Step 3: Gearing

Step 4: Exit

Step 5: Top

Step 6: The Arm: Middle Part

Step 7: The Arm: Entrance

Step 8: The Arm: Exit

Step 9: Completing the Arm

Step 10: Attaching the Arm + Side Support

Step 11: Finished!

You're done!
Thanks for building my lift. (or watching the ible only)
When you have used it in your ball machine, just give me some credit and let me now.
Then I'll add a photo of your Spinning Freefall Lift to this step!

See you!

Is the large wheel needed? If so is there any substitutes for it?

Thanks.

Yes it's necessary but you could use another gear combination.
But I'm not sure if that would work.
This combination has just the best rotation speed cause if it turns to slow or to fast it won't work anymore.

Mooie lift! Het meachanisme dat er voor zorgt dat er steeds maar een bal in kan is echt geweldig! Denk je dat die ook nog werkt met de nieuwe soort ballen?

author

Ik heb het geprobeerd maar spijtig genoeg is de tunnel te smal, zoals ik al dacht.

author

Oke da's wel jammer. Maar ik kan hem modden als ik hem ooit wil maken.

author

Als het je lukt mag je er zeker instructies van maken! Misschien dat ik binnenkort eens een andere probeer te maken voor de nieuwe ballen.

author

Misschien maar ik vrees dat die in de tunnel blijven vastzitten. Ik zal het je laten weten.

Wha, cool lift! I especially like the gate! :D

author

Yes I almost gave up and then the gate worked! :) You can use it for a next ball machine! ;D

author

Haha, thanks, but my next ball machine just has a chain lift :P (But the lift is taller than 5 meters)

author
jameshond (author)Sorunome2012-05-28

woooooow 5 meters!!!!!!!!! nice

author

that's crazy!

author

That's the worlds largest knex ball machine :P

author

When will he be finished?

author

probably next week....

author

cool how many paths?

author

one ^^

author

a freefall? :D

author

Nope, if it was a freefall i'd already be long finished. I'm also braking the world record of the worlds biggest knex ball machine looping :D

author

Great! wich ø meter has the looping?

author

i think it'll be about 9 red rods in diameter.

author

woow! can't wait to see it!

author

haha, me neither xD

Nice job! Probably one of my favorite lifts. I'll build and use it once I get my parts back.

author

"once I get my parts back." ??? Don't you have them anymore?

Oh almost forget: Thanks! ;D

author

I'm moving which means my parts are packed away which means I can't build :(

author

:( for how long?

author

1 to 2 weeks :(
