Cornish Boiler

Cornish Boiler: Normal single-flue boiler for low steam production.
Cornish Boiler (Normal Plate): The same Cornish boiler built from ordinary plate instead of boilerplate: cheaper, capped one atmosphere lower.

The crafted block is the firebox end of the machine: place it facing the way the barrel should extend, and the casing rises from the cells ahead of it as each stage is built. Right-click with a stage's materials in the hotbar to raise it, and ctrl plus shift plus right-click outlines what remains. Get the facing wrong and there is no turning it afterward; the whole casing has to come down and go back up.

Complete, the block is also the machine's control panel: the main hatch and the man hatch both open from it, and its look-at line carries the water, steam and pressure together. See Steam and boilers for firing it and for what an unvented boiler does.

The normal-plate build is the same boiler from ordinary plate instead of boilerplate: cheaper to raise and capped one atmosphere lower, at 4 atm against the boilerplate build's 5. That ceiling is the difference between feeding a Watt beam engine and feeding a simple horizontal engine at its rated pressure; the layout, the stages and the controls are the same.
