Cornish Engine

High-pressure beam engine whose steam intake can be throttled up or down. Drives one attached sub-machine.

The crafted block is the cylinder end of the frame: place it facing the way you want the beam to run, then right-click with each stage's materials in your hotbar to raise the rest of it. The sub-machine that takes its power sits two cells out in front, where the beam swings, so an engine built with nothing in that cell just stands there drawing no steam at all.

Its steam comes off control rods with three settings, low, normal and high, worked with a wrench on the engine's own cell or the cell directly above it. Low engages at 5 atm and draws 8 L/s, normal at 6 atm and 16 L/s, high at 7 atm and 32 L/s, and every setting wears above 8 atm, so a Lancashire Boiler at its 12 atm choke needs a pressure valve gated at 8 atm or under on this engine's own run. Running hot for 60 s past the wear point breaks it; a wrench reads the repair bill and the materials go in on a second right-click.

Choose the setting for the line feeding it, not for the load: a starved line does not stall the engine, it just delivers less power for the same steam drawn.

Interaction

• Right-click to raise steam throttle
• Right-click to lower steam throttle
• Right-click to repair
