Knex Ball Machine - Off the Wall


Here's the most recent project of mine. Its a ball machine build entirely in my bathroom. It was a fun challenge and produced a very unique ball machine I think. Nothing too fantastic in terms of elements or anything. The triple loop, chain slide, the geared ferris wheel and perhaps the double helix thingys are the only things worth really noting.

Anyway, hope you folks like it. Sorry about the photos being so dark, its hard to get good lighting in a small room with no windows.



Total piece count: 8891.
That makes Sproutless the winner with a guess of 18,500. Congrats!

tht is cool but why did you build it in the bathroom?
I_am_Canadian (author)  knexinventer5 years ago
As a unique challenge.

And thanks :-)
your welcome:)

Any mention of the toilet would be FAR too easy, so...

How long does it take for the ball to travel all the way around?
I_am_Canadian (author)  DB20165 years ago
It changes quite a lot for the different paths, the longest one... Perhaps 20 seconds?

That's very impressive, if I tried that my dad would axe it all down and tell me to clean up the mess haha. Very cool!
I_am_Canadian (author)  DB20165 years ago
Thankfully my parents are fairly tolerant :-)

No problem. Will you post?

Just kidding. That is sick man, can't wait to see what's next.
I_am_Canadian (author)  DB20165 years ago
Cheers :-D
I was wanting to make something like this to but i was affraid id loose parts...
few green rods went down the bath drain, but I think those were the only losses :-)

Does it get in the way at all?? Also i like how you built this with intent on challenging yourself, not to just post a giant mega thingy to post.


I_am_Canadian (author)  KnexFreek5 years ago
Just a bit, its not a huge deal. Thanks very much friend!

So how do you shower without wetting the knex?

Nice job though, and it bring small entertainment to anyone that's using the bathroom.
I_am_Canadian (author)  username2525 years ago
I use the shower in the other bathroom :-)

How did I not notice this??? I remember seeing i on youtube a while ago. Great ball machine dude. How did you convince your parents to let you do that? :-P
I_am_Canadian (author)  Tornado965 years ago
Thanks! My parents were all for it actually :-)
Lol If only...
Quit complaining, you have a huge patio to build in. :-P
Good point >:-D
...which gets so hot that it warps your Knex. :-)
I_am_Canadian (author)  Shadowman395 years ago
I take it you folks know each other...?
Yes, haha.
Wait, you seriously know Tornado? Like you've met him in person?
No, we know each other via Skype.
Yo, Lets skype sometime. kevinc9933
Funny that you say this, because I added you a few days ago. :-P You just haven't come online yet.
whats the lift called?
I_am_Canadian (author)  patriots88885 years ago
Called? Its just an ordinary chain link lift.
sorry im not very good at knex and i might want to build that lift
I_am_Canadian (author)  patriots88885 years ago
I like to call it Larry, but it goes by a pile of names. I'm sure there's an instructable on how to make it someplace.

Nice! I LOVE the element on the lower right. :-)
I_am_Canadian (author)  Randomguy655 years ago
Thanks! It works well, I like it too.
lol i fell for the mirror trick i actually thought it went further back!
i like your ball machine esecially the mirror effect. That was funny when all your pieces was in the tub. Also I just finished my first ball machine.
I_am_Canadian (author)  bnsfwarbonnet5 years ago
Thanks and congrats!
Shadowman395 years ago
I love it! :-) The micro loops are my favorite part.
I_am_Canadian (author)  Shadowman395 years ago
Thanks! I liked them too. Kinda ripped them off one of your older ball machines I think :-p
Haha, that would be Wipe Out. :-P Do the Knex pieces get wet in the shower?
I_am_Canadian (author)  Shadowman395 years ago
Thats the one :-)

I never actually showered in that tub, we have a nicer shower that we use instead.
Oh, cool. I guess it would get wet though.
I_am_Canadian (author)  Shadowman395 years ago
Yep. Not sure if that does them any harm though.

I_am_Canadian (author)  instruct395 years ago
Nah, our other bathroom has a much nicer shower anyways, so we just use that.
haha! i figured that anyways, its the same way at my house, except the shower we dont use doesnt have knex in it :P

Wasn't that a bit awkward when you actually wanted to use that room for its intended purpose?
I_am_Canadian (author)  The Jamalam5 years ago
Not at all. Very entertaining actually.

Are you going to count all pieces? Or is 8891 the final count?
I_am_Canadian (author)  Kairah5 years ago
8891 is the final.
Interesting. Nice though. How did you get your parents permission on that?
I_am_Canadian (author)  shadowninja315 years ago
Thanks :-) Parents were rather into it actually.
Really? Thats kinda funny. I really like it.

*pleads for your peices*
I_am_Canadian (author)  ajleece5 years ago

Look on craigslist. Tons of cheap Knex on there.
And then add about a billion dollars for shipping, remember? =p
I_am_Canadian (author)  ajleece5 years ago
Nah, just go pick it up yourself!
1k flight fares? Hmm.. I think i'll pass.

Is it hard to use the toilet or take a shower with that in your bathroom?
I_am_Canadian (author)  DJ Radio5 years ago
You can use them all, the shower gets some of the pieces wet though.
TheDunkis5 years ago
Now you gotta build one that goes around the entire house. I'm sure you could find your way into the news or a record book or something for such a feat.
I_am_Canadian (author)  TheDunkis5 years ago
Give me about a million pieces (literally) and I'll make it happen :-)
