Picture of The Official Guide to Knex Ball Machine Lifts
Ever since Wipe Out, people have been interested in building new lifts for Knex ball machines, so I made this guide!

This guide will include all of the ball machine lifts that have been built. In each step is a short description of the lift, a credit to the builder, and links to instructions/videos. If a lift includes at least one picture it'll either be added into an existing step or made into a new step. If a lift includes no pictures, but only a video, it will be added to the second to last step, titled "Lifts Without Pictures". This is to make the guide official, instead of only including lifts with pictures.

If you want your lift added or know of another lift to be added, just post a comment below with links/pictures. Please have good quality pictures, not ones that are blurry, fuzzy, dark, etc. Every builder is credited to their lift, usually with a hyperlink to their profile, but if you don't want your lift on this guide due to copyright reasons, just tell me and I'll take it off of the guide.

Please tell me if you have any suggestions or feedback for this guide. I hope you find it useful!

This guide started out with only 10 steps, but now it has over 70! The search bar below allows you to search steps by title, just in case you can't find a lift within the huge mass of steps. Thanks to Sorunome for programming it. :-)

New lift!


MisterBukweet6 months ago

I built this lift... I used orange track clips instead of the gray connectors on the blue rods on the helix... the balls go up much smoother.. awesome design.

Shadowman39 (author)  MisterBukweet5 months ago

That sounds like a nice addition, thanks for building!

correction ... oops.. I meant white rods... getting color blind in my old age.

The 2 lifts from Revolution :)



Shadowman39 (author)  sandroknexmaster9 months ago

Added! (They're located in already-existing steps)

Yay, thanks!

I was too late O_O

New lift:


Shadowman39 (author)  dickheijboer9 months ago


For some reason, whenever I try to make a lift other than a chain lift, it DOESN'T WORK. And I am getting VERY bored of chain lifts.

Shadowman39 (author)  TheUnfortunateHobbit9 months ago

Have you tried helix lifts or arm lifts? There are many choices, so at least one of them will have to work for you. I agree that chain lifts get boring, haha.

would it be possible to set the connected arm lift at a 45 degree angle?

Reaching 45 degrees would be difficult due to the formation of the ball holders in relation to the arms. Looking back on the multiple arm lift (step 30, my design) I think it is geometrically impossible to achieve 45 degrees or higher while keeping all arms the same size and shape, and keeping the parallel-like pattern.

You could ditch the parallel-like pattern and try something like the Right-Handed Arm lift (step 31), as it has consistently designed arms, then you could modify it to 45 degrees, but this complicates the gear system.

Yeah, you're right, I've been trying for days now and not much progress. It's impossible to get the arms to tilt enough to tip the ball onto the next one.

I had the same problem when trying to make a staircase of Small Rotating Arm Lifts (Step 17). I should probably try a smaller angle...

There was ACTUALLY instructions posted for the stepper lift before Retrograde:

Shadowman39 (author)  hunter9991 year ago

I think those instructions are incomplete.

I know this is a late reply, but I actually did use that link for the main structure (though never could find it after!) The problem was that it mentioned nothing about entrance and exit paths or the crank mechanism at the top. Those all had to be improvised...thanks again to knexpert#10829476 for making better instructions of the Stepper lift from my Retrograde pictures. :-)

Too bad bezempje deleted his account and ibles :-( This look like a cool lift/shooter.I'm gonna try to build this from the pics, if I succeed I will post an ible on it...
Shadowman39 (author)  hunter9991 year ago
I'm sure people will be glad to see an Ible of this. :-)
YAY!!!!! I rebuilt it perfectly!! :-D One Q - What height do you think this should reach? At the moment I seem to get 1 metre + in height.... but I have like 4 rubber bands on the end and the motor does not have enough torque so I am yet still tinkering around. I have also modified some parts of the shooter.

I can post if you would like, let me know and i'll begin a Ible if so. :-)
Shadowman39 (author)  hunter9991 year ago
That height sounds good. What type of balls does it use? You may want to ask Sandro before posting, as he has a similar version, I'm not sure if he was posting instructions of his. If this comment has any grammar errors then sorry, I'm having a hard time reading right now (blind spot)...
Sandro said his mechanism is completely different to bezempjes so I can post. Also it uses the newer K'nex balls: these ones. I'm gonna change it round though. It seems at the moment the 2 motors shown above do not have enough torque that is required, to make it worth building as it seems to be getting very very low heights. So instead im going to try a 12V motor and tinker one in. That ought to do it! :D (*late comment)
I'm sure bezempjes also works with the old style knex balls.
And as you can see, my version works almost entirely different, so please don't hesitate to make instructions when you're finshed! :D
Does it really reach more than 1 metre height? That's quite a lot, much more than I expected ;) That's probably the biggest difference between yours and mine: the height. Mine is more designed to attach in a white floor so it can shoot the balls from a lower floor to a higher floor (or something like that)
Shadowman39 (author)  sandroknexmaster1 year ago
I remember bezempje saying that his works with older balls but they don't reach a good enough height.
Yeah older style balls are heavier.
Shadowman39 (author)  sandroknexmaster1 year ago
Eyup, which is why I like them better. Only problem with them is the holes.
Ha, sometimes when I was building the white floors of my ball machines, the balls didn't roll because they landed on the hole >.<
Shadowman39 (author)  sandroknexmaster1 year ago
Yeah, they also get stuck on rods. I mean, the odds must be rare, but it happens often. o.o

Far too often.

And it sucks if, because of a rod sticked into the whole, and you notice it to late, some gearing gets destroyed in a lift >.<

Shadowman39 (author)  Sorunome1 year ago

Yeah, that's bad. :-P

ever thought about using that phenomina for making a lift, though? :P

Shadowman39 (author)  Sorunome1 year ago

No, it would have to line up every time, lol.

This would work on a ball machine with no turns... such as the Quark.

1 metre = manually, I am yet configuring round what to do as the motor keeps clicking since it is under a lot of torque. 4 rubber bands = 1 metre+ in height so I am trying to get a 12V motor since the torque is really high


Since this lift is made to fit a yellow rod scale and the 12V motor is for a blue rod scale, I am having a hard time tinkering one in :-/. The floor would have to be quite high for this lift (like the one in your ball machine: Euphoria it is a red rod raised off the ground).

IF I am successful, it will be in my next ball machine :-)
Yeah, back then people used yellow rod boxes, now most ball machines have red rod boxes.
But I'm sure you'll find a way to attach the 12v motor :D
Can't wait for your ball machine!
