Here the instructions for the new lift in my knex ball machine Dragonfire
I have changed the lift a little bit, more exactly the entrance.
In the vid of Dragonfire, you can see that there are several balls rolling to the arm at the same time, but the arm can lift only one ball at time, that's why there is an extra path (path 4).
In this new version there is another way to bring the ball to the entrance of the arm.
Now only one ball can roll to the arm, and not two (or more) at the same time.
If something is not clear enough, let me know!
PS: Thanks to KneXtreme for the name of this lift!
