Introduction: Knex Ball Machine Element: Tire Stairs
This is an element that I used a few years ago but I didn't have Instructables back then, but a lot of people really liked this element so I decided to make instructions for it. It's easy to build and works perfect. You just need the large classic tyres from knex. You can always watch the video to see it in action.
If there are any questions/ problems feel free to ask me in the comments below.
Thanks for watching/ building,
We have a be nice policy.
Please be positive and constructive.
