Instructions
Set the Ball Factory set box beside the building area. Building the Big Ball Factory set is intensive so you will want to refer to the pictures on the box often during construction.
Build the front of the Big Ball Factory first. Look at the photo of the complete structure to ensure correct construction. The set has three types of connectors for the rods that build the structure. The three types are used by inserting the head of the rod into the slot on the connector, snapping a rod into a connector and threading a rod through a connector. Some of the connectors have a locking system instead of a hole, which locks the rods in place allowing the 3-D structure to hold its shape.
Add the factory assemblies to the back of the construction. Gears are color-coded by size with yellow being the largest and blue being the smallest. Red gears are medium size, and you will use them to transition between the large and small gears.
Continue adding new sections until you complete the structure. When you become comfortable with K'NEX building, create your own designs using the parts in the set or combine sets for even larger structures.
Use care when constructing the pulley, crank and gear systems. According to K'NEX, "Builders must pay close attention to the positioning of Locks, Gears, Spacers and Connectors." If you do not connect them correctly, they will not operate as they should. Face any tan or bronze connectors that you are using as locks toward the gear and lock it in place.
