Introduction: Knex Ball Machine Platinum

Picture of Knex Ball Machine Platinum
Here it is. My ball machine. For this ball machine I focused most of my pieces on elements which means there is at least one new type element on every path. Now, I'm emphasizing the word TYPE because of there being different TYPES of elements. Let's take path 4 for example, when I say "New element: Ferris wheel" I mean new TYPE of Ferris wheel, or when I say "New element: Panel drop" I mean new TYPE of panel drop. I know both of those elements exist all ready I just mean there a new TYPE.
Now let's get down to specifics. This ball machine contains 13 paths (or tracks), one lift, 3 motors, and 16 new elements.
Let me know If want me to post a guide of all the elements.
Oh! I all most forgot there is a element in track 6.1 that is not shown in the pictures on account of me building it afterwords.Enjoy the video!

i am never speechless....WOW

KneXtreme (author)traceepratt2012-04-14

Thanks. Glad you like it :)

This is intimidating to my knex ball machine that I've been working on for 2 months

KneXtreme (author)2012-01-21

Thank you.

Thank you! I'll probably post the elements within the next couple of weeks.

JSF521 (author)KneXtreme2011-11-11

I would love that! Please also post your path selector, and the underside of your bowl structure at the base of your machine. I have always wondered how to put the proper bend in the bowl, and how to make good path selectors!


KneXtreme (author)JSF5212011-11-12

Actually the path separator I used was built by bezempje95 but for whatever reason the video is private now, so sure I'll post the path selector, and I'll post the bowel. You should also check out martijnb95's bowel which is a little smaller.

JSF521 (author)KneXtreme2011-11-13

Thanks, I have already seen that, but I meant the bowl system at the bottom of the machine. How do you set a good angle to feed the lift??? Also, I love how each element is used in several paths. Please post the ferris wheels (with the balls on the inside), and the arm assembly in the loops on Path #1.

I love your projects!

KneXtreme (author)JSF5212011-11-16

To be honest I just tinker around to get the angle I like. I'm not quite sure what ferris wheel your talking about? If you mean the the ferris wheel on track 10 those are not balls but gears. And if you mean the ball arm yes I am posting that. I hope that clears up some confusion.

JSF521 (author)KneXtreme2011-11-17

As to the bowl, 2 things.

1: What pieces do you use to support the bowl structure?

2: How do you connect the snowflakes so that they can bend like that???

martijnb95's bowl used a sort of tension structure, building little pieces and connecting them at the rim to support and bend, but how on a larger scale??

Thanks for all you help!!!

KneXtreme (author)JSF5212011-11-20

Actually the bowl is so big it sags from the weight, also the snowflakes just bend on there own. You can pretty much connect them any way you want.

JSF521 (author)KneXtreme2011-11-20

Okay, thanks!

JSF521 (author)KneXtreme2011-11-17

The loops and ball arm assembly at the end of path 1, and the spinning circles on paths 6, 7, and 8. (balls enter the circles on 6, 7, and exit on 8). Also, how did you do the half-loop, and make the transition on path 1 from the loops to the ball arm??? The ball went up, switched tracks, and came down. How??? ;)

KneXtreme (author)JSF5212011-11-20

Yes, I'll be post the loops and the ball arm soon. Oh! you mean the spinning circles, yes I'll be posting them as well in fact here is the link

JSF521 (author)KneXtreme2011-11-20

Thanks! Those are awesome elements!

Sorunome (author)JSF5212011-11-13

If I can help you, I made aswell a multiple path selector based on yardking's design. ( It works for me pretty good. :)

JSF521 (author)Sorunome2011-11-13

I saw that. I tried it, but it didn't work 100%. Something about the angle of the ball's approach. When the ball fell through a slot, sometimes the force would bounce the path selector off of the holding bar, resetting it, and lower paths would never run. Thanks, though. I love your projects, especially the parts sorters. :P

Sorunome (author)JSF5212011-11-14

Hehe, thanks. And to that error of my path seperator: it's rather simple to fix that, all you have to do is push the white rods with the tan connectors on them at the one where it turns back up slightly more in, maybe less than a millimeter, maybe more, you'll have to try out a bit and then it works without any problem! :)

Zeethesquirrel (author)KneXtreme2011-11-09

Cool do you mind if I use the alternative spiral track that uses the roller coaster things in my new ball machine?

KneXtreme (author)Zeethesquirrel2011-11-09

Nope. Go right ahead.

KneXtreme (author)Zeethesquirrel2011-11-12

Yes, I'm going post them Sat. Nov. 19th.

Sorunome (author)KneXtreme2011-11-13

six days left.... :D

knexpert#10829476 (author)2011-11-18

Can you also post that cool path selector as well?

Yes I will :)

knexpert#10829476 (author)2011-11-18

Can you also show the cool path selector as well?

1dog789 (author)2011-11-16

can you make a step by step diy?

KneXtreme (author)1dog7892011-11-17

If you mean the ball machine, that's almost impossible. But If you mean the elements I'll be posting them in a couple of days.

speedracer425 (author)KneXtreme2011-11-18

Maybe, you could post around 7 instructables telling and showing how to create it. Just my input. Good ballmachine

knexpert#10829476 (author)2011-11-16

Thank you very much!

Nrogers192 (author)2011-11-12

You are the best knex builder ever!

KneXtreme (author)Nrogers1922011-11-12

Thank you!

Sorunome (author)2011-11-11

That's nice! You just earned yourself a subscrition! :)

KneXtreme (author)Sorunome2011-11-12

Thanks a lot!

knexpert#10829476 (author)2011-11-10

This is so awesome!. Please post some of these elements.

martijnb95 (author)2011-11-08

i mean wow man! well done i didn't expected 13 paths! :D

KneXtreme (author)martijnb952011-11-08


martijnb95 (author)2011-11-08

cool! i)

I_am_Canadian (author)2011-11-08

Beauty! I really like it.

GrandeSwag (author)2011-11-07

Last path is really great. Nice layout too.

KneXtreme (author)GrandeSwag2011-11-07

Thank you!

jbussé (author)2011-11-07 do this for a living or do you do it after a day's work
anyway: it's incredible

KneXtreme (author)jbussé2011-11-07

Thanks! And no I don't do "this" for a living.

~KGB~ (author)2011-11-07

5* amazing! =D

mikeasaurus (author)2011-11-07

Amazing build, I love ball machines!

imans314 (author)2011-11-07

I love it!
