Civil Grinder
The Civil Grinder adds steel, cast iron, plastic, and chromium-related components, including cast iron pipe, plastic pipe, metal hinge, and chromium steel bearings.
How it works
The output table lists iron latch, cast iron pipe, plastic pipe, metal hinge, iron wire, and chromium steel bearings as Civil Grinder products, with associated materials. The passage specifically notes that the Iron Latch recipe must be bought from the Commerce Guild before crafting, and reports a bug affecting when the book appears. The source says the unlock appears to follow the water tower repair in the main story.
