Here are instructions for one of my biggest elements so far. I never had a problem with it in my Ball Machine Eclipse, it works really smooth and works 99% of the time. If you want to use this element make sure your Ball Machine is solidly built and can support a lot of weight. Just to let you know, there is a possibility that your machine shakes a little bit when the arm comes back up. It depends on how big and solid your machine is. you can always watch the video to see it in action.
If there are any problems/ questions feel free to ask me in the comment below.
Thanks for watching/ building,
Step 6: The Chain
Step 9: The Axle
There are 2 blue spacers on each side of the axle.
Step 11: Little Detail
If the ball doesn't land on the exit path, then you just need to attach a green connector with a green rod on the exit path.
