uh about the parts list ballmachine balls?

[Bartboy]

does it have to go up and down to qualify as a ball machine?

[jollex]

Yes.

[Bartboy]

aww, look at mine , it is THE MOST POINTLESS thing ever, but if you say it has to go up ill add a ramp.

[dannypalmer2001]

i like it ,is it on this site

[jollex]

MIne is smaller, :P

[Bartboy]

somewhat, mine uses less rare pieces, can use any motor, needs no chains or gears, has a carrying handle, and uses less pieces.

[DJ Radio]

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

[Bartboy]

yeah, but if you have one of them, you have all of them, and has nobody showed you how to substitute pieces?

[DJ Radio]

no, i dont have any parts like that

[jollex]

True.......but mine is smaller, :P

[Bartboy]

yeah, it is, but I built it and it keeps jamming!

[jollex]

Where?

[Bartboy]

the chain just suddenly locked in place, even when I had a hand crank.

[jollex]

Then you probably made it wrong.

[Bartboy]

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;

hi

[jack999]

[Knexpertevan]

It appears that you have different views of the exact same step or do you make three of the exact same piece??

[jollex]

When it says 1-3 instead of 1 then 2 then 3 it means it is just different views.

[Knexpertevan]

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 :(

[Knexpertevan]

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]

You just connect the smaller parts in each step and at the end you connect all the steps.

[Knexpertevan]

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]

No you make each individual step and then connect all the steps at the end.

[Knexpertevan]

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]

No problem.

[anaconda]

i pressed the wrong button. ARRRGGGHHHH!!!!
