Introduction: Curly Fries | K'nex Ball Machine Element

Hello there again! Here I have for you instructions for my BRAND NEW motorised ball machine element!

Originally I wanted to make a lift from the standard spiral staircase turned diagonal however that didn't work out very well...So I turned it sideways and made an element! After many many fails and mistakes it is finally here. Good luck building it! ➡

Step 1: Step 1 - Frame

Yay! You took the time to actually make my element. Thank you for building it! Please tell me all about it in the comments and show me a picture! Now, if it doesn't work quite right here are some troubleshooting steps:
• Is the guard rail straight? If not it can easily catch the sides of the frame and make it jittery.
• Have you turned the motor on the right way? If not, well it isn't going to work! Push the slider right to turn it on and start the element.
• Is the exit aligned with the white snowflake connector? If not the ball may not exit correctly. You can achieve this with spacers or without them.

Step 8: A Few Fixes!

After recently getting 3 more k'nex balls (Now I have 4!!) I realised this element doesn't work when they stack together in the waiting area. I spent a long time trying to get them to go one ball at a time and finally managed it however you may have to play about with some of the placement to get it perfect. Here it is:

1: Overview
2: Build these
3: Assemble
4: Add these

If it is a bit jittery, replace the medium gear with a large gear. it will be slower but will work better

Oh and check the last step to improve the entrance so it's more reliable :)

Cool element and very clear instructions

Thanks :D The one thing I really hate is unclear instructions. with me, all my ibles will have clear instructions and I will spend a lot of time on them :D This took me roughly 2 hours to make!

Linkin_J_Knex (author)Lexi Knex2015-09-27

Thank you! Your English is fine :) I know a tiny bit of French but not enough to speak French to you sorry. I'm glad to hear that you will/may build it!

Lexi Knex (author)Linkin_J_Knex2015-09-27

wait but how it work ? does the stairs turn and move the ball ?

Linkin_J_Knex (author)Lexi Knex2015-09-27

Yes. the stairs spin on the axis and the ball moves through it like a sideways spiral staircase. a video will be up in a couple of days
