K'nex Dual Axis Arm Lift

This is the K'nex Dual Axis Arm Lift designed by KnexTech.

I downloaded a PDF file that contains images and text on how to build this from the Instructables.com web site.

I then modified the entrance and exit so that the balls would run continuously in a loop as shown in the final section of the video.
