Bartboy5 years ago
does it have to go up and down to qualify as a ball machine?
jollex (author)  Bartboy5 years ago
Yes.
Bartboy jollex5 years ago
aww, look at mine , it is THE MOST POINTLESS thing ever, but if you say it has to go up ill add a ramp.

jollex (author)  Bartboy5 years ago
MIne is smaller, :P
Bartboy jollex5 years ago
somewhat, mine uses less rare pieces, can use any motor, needs no chains or gears, has a carrying handle, and uses less pieces.
actually, most of the parts on your thing are rare. if you want to know what i am talking about, they can be found on the stock of the storm 222
yeah, but if you have one of them, you have all of them, and has nobody showed you how to substitute pieces?
no, i dont have any parts like that
jollex (author)  Bartboy5 years ago
True.......but mine is smaller, :P
Bartboy jollex5 years ago
yeah, it is, but I built it and it keeps jamming!
jollex (author)  Bartboy5 years ago
Where?
Bartboy jollex5 years ago
the chain just suddenly locked in place, even when I had a hand crank.
jollex (author)  Bartboy5 years ago
Then you probably made it wrong.
Bartboy Bartboy5 years ago
fixed! now it goes up 2 centimetres, then just falls, gos around, up again, falls etc. etc.

Hi i was just wondering can i post my own instructables on this?
It's a modded version becauase 1 less blue ones because alot of people (including me) don't have that much of blues and 2 it uses a different motor because again people don't have (including me) that kind of motor

p.s.i will credit you!

2 comments...1:If you read down all of the comments so far, there are like, 10 'It is posted!'s. 2:If you watch the video, towards the end, the balls hitting the track switcher are in perfect sync with the clapping in the music! See for yourself;

It appears that you have different views of the exact same step or do you make three of the exact same piece??
jollex (author)  Knexpertevan5 years ago
When it says 1-3 instead of 1 then 2 then 3 it means it is just different views.
Ya I thought so, we just did that and it worked (kinda). There was a few fundamental errors though, mostly the chain, it kept getting stuck different places :(
I don't quite get if your connecting the steps each time or making every individual step THEN connecting them, like, I know you connect at the end, but im wondering if you connect 1 and 2 and 3 then make more and connect that, I just don't get it really, plus the last picture is a little too close so i cant tell how to connect everything............ have any um.........suggestions?? Thanks.
jollex (author)  Knexpertevan5 years ago
You just connect the smaller parts in each step and at the end you connect all the steps.
Because in step 3 I dont see step 1.......and do you just add step 2 and 3 together?? Cuz also I dont see step 4 in step 6........................ its just kinda confusing.....
jollex (author)  Knexpertevan5 years ago
No you make each individual step and then connect all the steps at the end.
OK thanks..............I'm having a k'nex party this afternoon and I though it would be fun to make a little prototype to start out with so thanks again!
jollex (author)  Knexpertevan5 years ago
