Turbine Builder

The Turbine Builder builds the turbine for you from items in its inventory—similar to the Reactor Builder.

Typical workflow

1. Place the builder on the face where you want the turbine shell to start.
2. Open the screen and set width, height, and depth (within your pack’s size limit).
3. Stock the builder with casing, glass, rod controller, rods, blades, and the storage blocks you want for coils.
4. Pick a layout:
   • Efficient — fewer rod columns (checkerboard); blades grow ring by ring up the shaft (+3% height bonus possible—see Rods and blades).
   • Productive — rods on every allowed column; each layer gets full rings right away (maximum steam sooner).
5. Choose coil type (cycles the metals the mod supports) and how many coil layers (default 3, change with ◀ ▶ on screen).
6. Use preview and the simulation panel to see estimated RF/t, steam use, and materials needed.
7. Mark input tells the builder which inventory slots supply which blocks for each step.
8. Press Build when ready. You can add fluid to the builder tank if your pack uses that for setup checks.

Build order: outer shell → rod controller and rods → blades → coil blocks in the top interior layers.

Simulation panel

Shows whether the layout is valid, expected RF/t and steam, coil and blade bonuses, and a material list—same idea as the reactor builder. Button names can vary by version; read the tooltips on screen while you work.
