737 Einzelne Kontrollsäule (SCC)

Build a smoother, simpler Boeing‑style control column for your home cockpit.

This new SCC revision centres on a widely available 75 mm OD PVC pipe (replacing the old 82 mm spec) to make sourcing easier and assembly faster. The mechanism removes the linear actuator for a cleaner, more robust build, and upgrades sensing to hall‑effect on both the control head (roll) and the base/pitch lane for precise, drift‑free inputs. An optional gas‑strut head delivers a notably improved tactile feel that early testers have praised.

What it is & why it matters

Purpose‑built for flight sim: A printable, mechanically sound single control column that brings Boeing‑style yoke ergonomics to your sim pit without exotic parts or CNC requirements.
Originality in the revision: A ground‑up simplification around 75 mm PVC, deletion of the linear actuator, and a reshaped control head—now with hall sensors—for accuracy and long‑term reliability.

Essential for builders: Fits a 220 × 220 mm print bed, uses commonly sourced hardware, and comes with a comprehensive parts & build guide—so you can focus on flying, not guesswork.

Key improvements in this release

75 mm OD PVC core (highly requested) for easier sourcing and lighter overall package.
Linear actuator removed → fewer moving parts, simpler assembly, less maintenance.
Hall‑sensor control head + hall‑sensor pitch lane → smooth, precise, and contactless measurement.
Optional gas‑strut head → markedly better, more realistic feel (widely praised by early builders).
Roll channel damping → accepts up to 2 rotary dampers to tame oscillations and improve centring. (Note: suitable dampers have become harder and more expensive to source—see “Limitations & sourcing notes” below.)
Refined yoke & control‑head geometry for fit, serviceability, and feel.

What’s included

1) STL/3MF print files for the SCC assembly (yoke, head, base)
2) CAD for all parts including the GAS damper MOD
2)STL print for Gas Damper MOD.

THERE IS NO BUILD OR PARTS GUIDE FOR THE NEW GAS STRUT MOD!

Context of use

Designed for desk‑ or cockpit‑mounted sim pits and compatible with mainstream PC flight simulators via your preferred USB controller interface.
Ideal for Boeing‑style setups where a single central yoke is desired, with optional damping and gas‑strut tuning to match personal preference.

Limitations & sourcing notes

Rotary dampers: The specific models used historically are now harder to source and pricier in some regions. The design supports running one, two, or none; feel is tunable; alternatives are noted in the guide.
PVC pipe: Must be true 75 mm OD. Regional nominal sizes can vary; verify OD before printing press‑fit components.
Temporary videos: Please use the temporary build videos referenced in the guide until the updated YouTube series is released.
