This is my first ball machine. It is a moderate sized machine with two paths. It features five elements throughout its course and stands about 2.5 ft. tall. A video should be posted shortly, if I have the time to make one. Feel free to comment below if any steps are unclear. Enjoy!
P.S. I didn't do a piece count because the machine used quite a few parts. Sorry.
Also, my latest ball machine can be found using this link:
Step 1: The Base and Ball Queue
This is the section of the machine that supports the tower. It may seem slightly unstable now but will become sturdier as the left and right attachments are added. The base also holds the ball queue where the balls wait to be carried to the top by the chain lift.
Step 2: The Main Tower
This is a long and repetitive step. It is probably the most crucial part of the entire ball machine. The tower holds the motor, path alternator, and most of the elements. Make sure you pay attention to all connector placements as well as how to attach individual pieces to the main structure.
Step 3: The Motor Attachment
This section drives the chain lift. Remember to closely examine the spacers between the connectors. The motor shown here can be substituted for any K'nex motor.
Step 4: The Path Alternator
This determines which path the ball will take.
Step 5: The Left Attachment
This section provides extra base support and holds some of the elements on path one. Build the first part, then the second part, and attach both to the main structure.
Step 6: The Right Attachment
This part serves the same purpose as the former step, and holds the path two elements. Build what you see in the pictures and then attach to the main structure.
Step 7: Connecting Path 1
This path leads to the first element on path one, the red ball drop.
Step 8: The Red Ball Drop
This element has been featured on many ball machines throughout this site. It consists of an arm that lowers a ball while keeping it parallel to the ground. Build the element's supporting device first, then build the arm itself.
