A semi-huge project. This ball machine is around five feet tall and has almost 5000 pieces. I designed a wheel gate to make sure only one ball occupies the bottom of the lift. Enjoy building this ball machine as much as I did creating it. This machine also uses the newer larger K'nex balls.

Yet again, another wonderful ball machine! How do you churn them out so fast? (I'm still stuck on a troublesome element, so my next release will probably be a while.) A well conceived lift system and creative elements. I love the instructions as always; they allow me to catch things I might otherwise miss in the video. Good job, a five star (if ratings were still up) machine! <br>P.S: PLEASE DON'T STOP BUILDING! ;-D
I also like your positive and encouraging comments, even if they're not for me :D
&nbsp; &nbsp; &nbsp;I like to follow 1 Thessalonians 5:11 - &quot;Therefore encourage one another and build each other up, just as in fact you are doing.&quot; Besides, who likes the people who gripe about the one tiny flaw of a model when there are so many positive aspects to applaud? My specialty is being the voice of&nbsp;<em>constructive</em>&nbsp;criticism, and encouraging people to keep at it and keep improving!
Are you talking about what I put at the end of the video? I have a problem with pointing out flaws and really need to control it.
Sorry, no, I hadn't even thought about that part of the video. I was more speaking generally...besides, my models often have flaws like that too, so why judge? ;-)
Good point!
This comment made me feel so happy, unfortunately I'm at sort of a block after that project. Hopefully I can get some ideas soon so I can continue with my projects.
<p>im glad u have instructions for the track(unlike most people) but does anyone here know what i can use as a ball. as a kid i lost mine and rather than buying a new track to get a ball ide like a cheap alternitive of what i can use</p>
what process do you go through, making instructions for ball machines? I want to make an 'ible for mine however I don't know where to start making instructions!
My 6 year old son and I just finished building this ball machine last night. Good times! Thanks for putting up the steps!!!!
<p>wow i only needed 4 more green rods i had to use 4 black ones instead O.o</p><p>great ball machine it works perfectly for me</p>
can you use golf balls instead of the k'nex balls?
its a big machine with instructions most ball machines don't so that makes it awesome <br>
oh f$%*
Nice, great again!
Nice! All classic K'nex pieces?
This is amazing...
Great as always! The element at 1:40 is nice, I think I'm gonna use it in my ball machine. <br>You should buy some more knex, then you can try to make a big ball machine.
oh I have way more knex than just what you see. I've just kept these projects at a minimum. This takes probably a fourth of my pieces!
Only a fourth!? Then try to make something bigger! :D
But then instructions get harder! ;-) No really, you should try going bigger, knexpert. I have found from experience that while simplicity is key, bigger is often better...it just adds so much potential!
Yeah and it's cool how you make clear instructions for smaller knex ball machines, but it's not necessary to make instructions for a bigger one (like 10000 - 15000 pieces, or even more if you have them)
I'm working on one now. It is a little under 6 feet tall and has an automatic drawbridge path that has two on-off switches that control a mother switch. There will be five paths as well so you will definitely get your bigger machine:D
Nice can't wait :D
Sounds great! And I thought you said you had &quot;builder's block&quot;! <br>;-)
Also, I have limited space where I build so I'm limited in size.
I really like your ball machines. They're well planned out.
BTW Congrats for being featured :D
Dang! You really are good at making ball machines! I'm always very impressed that you include complete guides with your ball machines as well, a very rare thing that you do very well.
