Introduction: Knex Ball Machine Element: the Scale
Here are instructions for the Scale Element.
It doesn't use too much pieces and is quite reliable.
You can watch the video above (9 New Knex Elements) to see how it works
If you want to build this element, make sure to check out Step one to see what rare or special pieces it needs.
If you don't have one of the newer knex balls, don't worry, it works with the classic one's as well.
Thanks for building/watching,
