K'nex Ballmachine Element #2

This is a cool element that you can use in any ballmachine. It works realy smooth and realy great. You can check out the video to see it in action.

Thanks 4 watching/ building.

This is the piece were the arm will be hold in place and were the ball will enter the arm and go out.

these are the last steps. now you just have to bring the arm and the structure together, and it's ready!!
