Chapter 03 · Copper
Tree sap, rubber, fluids and improved logistics.
Main production route
Rotation Mechanism → Copper Sheet → Rubber → Glass → Mechanical Press → Sealed Mechanism.
Use a Rubberworks Sapper; maple trees are the preferred high-sap choice. Compress 500 mB Resin over a passive heater such as a lit Campfire, then smoke Raw Rubber. Three Rubber craft three Belts; three Dried Kelp craft one. Eight Sealed Mechanisms around a Copper Casing make a Copper Machine.
Your milestone
Produce Sealed Mechanism consistently before expanding its consumers. Keep a buffer of the previous chapter’s components and a route for incomplete items to continue through the line.
