This is my final ball machine for the rest of the year since I have to go back to college. I wanted to end my ball machine spree with something huge and this is what came out, a 6' 10" high tower with five paths and a new element made by me. That element is on path one. This project took a lot of my knex to the point where I ran out of green rids!, I had to start using the black ones. Anyway, I hope you enjoy building this beast. This ball machine has the most pieces out of all of my ible's, 8,600!

Hi, I'm having a go at building this but having a few issues with the new cart element. Can't seem to get the weight right to make the cart move either up when empty or down when it has balls in it.

Any suggestions?

WD40 always works. Grease the track with it:D

Very good!
My only comment is that maybe you should record the lift(s) at the beginning of
the video. You could look at my ball machine video.
Just click on my profile and look for "automated a k'nex
ball machine".
Otherwise, very good!
I love the white mat/floor/whateveryoucallit

Oh my god, thank you for reminding me because if I did test the lift out, I would find that I made the chain claws wrong! I never put the part on that pushes the ball off the claw! Thank you so much for pointing this out even though you didn't point it out:D

Your welcome! (late reply... sorry!)

knexpert#10829476 (author)  www1392 years ago
Yes I should, thank you for the feedback:D
your welcome!

I ran out of all my yellow rods, blue rods green rods and yellow connectors on the last step... Grrrr

hi im josh! im 11 and I nearly finished this! I (my dad) orded some knex and it got lost in the mail so I never finished this project! I just want to let you know if you are 11 or over you can with ease start this project! I also had some problems with the new cart element but I fixed it, anyway great intractable and keep up the good work!

Look at the fourteenth picture in step 3

How much K'nex do you actually have? Just wondering
I'm guessing around 20,000. I'm only using my classic knex not my metallic ones.
Why did you post the same reply twice???
I pressed it once, nothing happened so I assumed I didn't hit it so I hit it again.

Great ball machine! Took me almost a week to build!
This machine is exactly 1 blue rod too tall... I can't build it on my table.... and I was going to say something really truly nice about this machine.. Seriously... I'm on step 7 and everything is looking way cool... can't wait to finish this... I hope my girlfriend doesn't miss her pot lid.
Aww man, I feel bad for you, one blue rod:D
170 Chain Links isn't enough either. Perhaps you should update that. :)
are you sure..... in my build 170 chain links worked perfectly

Thats awesome, a worthy winner in the contest! :D
Good job on your contest win! :-D
Congratulations for being selected as a finalist in the Toy Rods and Connectors Contest!

I forgot! Click the link, not the embed. It won't work.
Neato! :-D
By the way, what is the metal circle near the bottom for?
When the ball goes down the chute on path 2, it will hit a lever and hit the pan lid making it "ding". I never use the oven so why not put some use to those pan lids?:)
Nice! I'd have to say that my favorite part of the machine is that wheel cart thing (oh yeah, that's the new element, isn't it?) ;-)
Yes it is:D
