For attaching the shooter to the frame, we first needed to make some changes to the frame itself.

Attaching the wheels and the gears was fairly easy, the only challenge was adjusting the distances between the wheels.

However attaching this mechanism required us to move the motor of our conveyor further down. We thus decided to drive both sides of the polycord conveyor using chains.

Since the motor of the shooter was in the way of the polycord, we had to attach spacers under the pulleys.

Testing this we found out that the shooting wheels were too far apart when the polycord was adjusted correctly. To solve this we put 3mm spacers under the pillow bearings of the pulleys.

Also to fixate the distance between the left and the right side we decided to attach a U-formed construction to the top.

This works fairly well and reliably! Next we’ll need to attach more structural support and complete the wiring.
