 dont know to build this or immueble??? i know il build both!!
this is so cool, can you make this but as a bigger version pleaz also can someone help me as i can't rate
The whole point of it being small is that is supposed to be a small ball machine, what are you?
i didn't say it was small i was just askin if you could make it into a bigger version
If you want a bigger version, check out my ball machine, it also has a ferris wheel and two ramps, it's only bigger and a different lift system:
If he made it into a larger version it would defeat the point of it being small which is what it is meant to be. If you want to build a large ball machine, find an Instructable that actually shows how to build a large ball machine.

I built this ball machine a few days ago. Every day I've added at least one more different path/element. My final addition, which I'm working on now, is a double helix lift. The basis, obviously, is the Project BOX Ball Machine.

zzgs how is it a fake? So its small Darth trainman is just trying to post someone for every on if they have 1000 or 10000 pieces so ha
I almost agree with you, except I don't think something with 103 purple connectors and 197 blue rods is something everyone with exactly 1000 pieces would have (except perhaps for me...I have 640-ish purple connectors and about 750 blue rods, but even then...)
WHAT THE FU** THAT IS LIKE A BAJILLION PIECES i really need more knex. but sadly, i also need more money..............
Me, have a bajillion pieces? I doubt it. More like 7,500 for me. The Big Ball Factory comes with loads of both pieces.
but still 750 blue rods, i dont even think i have 100, or 75, the most i have is like 77 red rods. but thats about it. oh and about 145 yellow connectors.
That's still quite a lot. You could build some cool ball machines with that amount of pieces. P.S. I now have almost 900 blue rods.

Psh... 2000+.
HOLY CR*P, how long have you been collecting? plus, HOLY CR*P YOU HAVE ALOT OF PIECES, you have more blue rods than i have pieces nearly, thats nucking futs. plus, i asked the knex weasel about lifts because i have no chains, u know any ideas?
look at i-am-canadians lift i recommend it
me to
ok then, ill try that out, i might make one sooner or later hopefully.
That's true, Trainman has about three times as many pieces as me.
Darth Trainman (author)  The KNex Weasel6 years ago
yeah i could, but some of the required pieces i need i dont have, plus i have no chains? any other ideas on lifting the ball upwards?
Thats a good set man...
I didn't know you were here.
