Watt Engine
Low-pressure beam engine. 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.
It has no throttle: it engages at 2 atm and draws a flat 30 L/s whenever the line can supply it, wearing above 4 atm. A Cornish Boiler chokes at 5 atm, above that wear point, so a Watt behind one needs a pressure valve gated around 2.5 to 3 atm on its own run or it breaks. 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.
