Have you ever wondered about how I make my Ginormous and Wondrous Ball machines? Now you can design and build your own!

This instructable does not give steps on any particular ball machine, but rather how to build one in general.

Ball machines are the luxurious side to k'nex; these use thousands of pieces. If you do not have thousands of pieces, but rather have somewhere around 400, this is not for you. Sorry. You could always try, though.

These steps are essentially what I do when making my machines.

So, onwards!

Step 1: Preliminary Issues

Picture of Preliminary Issues
First of all, if you're reading this, hopefully you have a very large reserve of K'nex. Depending on your size and Concept, you will need varying amounts. on AVERAGE, 2 feet or less is about 1,000 pieces, 3 feet or less 2,200, 4 feet is about 3,000 5 feet is about 4,000, 6 feet is 5,000, and 7 feet, like the -xXxXx-, would be about 8,000. After that, your ball machine will get skinner and there will be less and less pieces, up to a point.

Second is possibly the most important step, as it will save you countless hours. It will be painful, but, SORT THY PIECES! Yes, take apart ALL your models and get many, many bags (or Boxes). Sort them all!

What you Need to build a Ball Machine:
Leather Fingers
Thousands of pieces
Bags or Boxes
Lots of Spare Time
This Instructable!

And next, the building? Hecks no! You still have much to learn, young Skywalker! do NOT start building your first ball machine yet, or you might make a FATAL ERROR! (Like I did when building Project DESTINY)!!!

You should be done with your painful sorting after a few days, so then, again, onward ho!

Mr. Trainman is about 2,000 pieces good enough? I have like 6,000 but lots of them are micro knex. PLEASE RESPOND!!! I NEED TO KNOW
It depends. 2,000 will probably limit you to a smaller to midsize ball machine, but is still very do-able. One thing you will quickly learn about building ball machines is that there is no set formula for building them. I would suggest looking at the various ball machines posted on the site, specifically for approximate number of pieces used, to see what is feasible for your collection (typing "knex ball machine" into the search bar will quickly yield results). Hope this helps!
Also, there have been ball machines with micro knex, such as sathothy's Armageddon. Link is http://www.instructables.com/id/Knex-ballmachine-armagedonn/

Just awsome.
I started making a paper ball machine which kinda looks like this but is much less complicated than yours.

what do you do if you do not have enough chain?, great 5* subed
Just make a ball machine that your chain can fit on.
have a look at the other instrcuctables it shows you how to do spiral lifts and mill lifts wich dont use a chain
You're a year and a half late.

LOL Me too!!
Same with me
A Machine infused with a Roller Coaster would be epic as soon as i get a good amount of roller coaster pieces i want to build a roller coaster that uses a ball instead of a train but then again it might not work...
