Additional Vertical Roller Testing
This was a test using dual 1/2″ rollers wrapped with duct tape. During the test, the rollers separated slightly after coming in contact with the ball once hitting the 3″ limit(simulates a spring loaded roller system). (There was a video here that has sadly been lost in the archives.)

Lifting Arm Calculations
Review the PDF linked below for calculations for the lifting arm. If the PTO is driven on the low gear side (14 to 64), then an additional reduction of approximately 8:1 will be required to drive the arm. This is easily achievable in two stages. If the PTO is driven from the high gear side […]

Vertical Rollers Testing
During the previous two days, we attempted to design and prototype different roller orientations with minimal success. Before we were able to record a video of the horizontal roller setup, we determined that the setup held the ball well(going forward). While attempting to move the prototype…
