What this is & why it’s essential

Building a 737 overhead is one of the most challenging parts of a cockpit—compound angles, tight tolerances, and alignment across LHS, RHS, and Center Overhead. This guide distills 11+ years of home‑sim experience into a practical, repeatable method so you can get the geometry right the first time. If you’ve struggled with angles, edge alignment, or panel spacing, this is the reference I wish I had when I started.

What’s inside (201 pages)
 
Complete Overhead Structure Plans: Covering Left‑Hand Side, Right‑Hand Side, and Center Overhead assemblies
Angle‑aware Drawings & Dimensions: Designed to reduce trial‑and‑error on tricky cuts
Build Sequence & Fit‑Up Guidance: Step‑by‑step assembly flow to keep parts square and aligned
Material & Costing Sheets: Practical material choices, quantities, and cost considerations
Tooling & Setup Notes: Tools used, cutting tips, and alignment checks for reliable results
Panels included in scope: Forward overhead, map lights, rope panels, bulb holder panels (structural context & mounting)
Eyebrow Windows Simplified: Fast‑build variant plus notes on swapping to print/CNC versions later (interchangeable)
Format: PDF (201 pages) • Language: English • Scale: full‑size cockpit build

Originality & approach
This is not a scraped set of diagrams—it’s a from‑scratch, scratch‑built workflow born of countless shop sessions, mistakes, and refinements. The eyebrow window treatment has been simplified for speed in this guide, yet remains dimensionally compatible with my 3D‑printed or CNC eyebrow variants available separately for members. Swap them in when you’re ready, no redesign needed.
 
Context of use
Home cockpit builders (B737 full‑scale) who want a reliable structural baseline before wiring/switching
Hybrid builds: MDF/ply, timber, or composite skins—drawings and callouts are material‑agnostic with notes where tolerances matter
Staged projects: Build the structure now, add avionics/electrical panels later
Limitations & expectations
You’ll need standard woodworking tools and confidence with angle cuts (mitre saw or equivalent highly recommended).
Dimensions and jigs are optimized for a full‑scale 737 geometry; scaling down will change fit/feel.
As with any workshop project, measure twice, cut once—I include methods that favor coordinate‑based layout and verification checks to avoid cumulative angle error.
 
Inspirations & credits / Remix notes
Inspired by real‑aircraft geometry and community best practices from the home cockpit world.
Remix‑friendly concept: Eyebrow windows are interchangeable with my 3D print/CNC versions hosted for members; credit appreciated when you adapt or remix structural elements.
 
What you’ll receive
1 × PDF (201 pages) containing:
Structural drawings, angle notes & assembly order
Material lists & costings
Tooling guidance and builder tips
Panel mounting context for forward overhead, map lights, rope and bulb‑holder panels
 
Who this is for
Builders targeting MSFS / X‑Plane / P3D home cockpits who want a solid, square, and repeatable overhead frame before wiring
Makers who prefer measured layouts over guesswork—especially where angles make or break the build
 
FAQ
Q: Does this include 3D‑print STLs or CAD?
A: No. This product is the build guide only. (3D‑print or CNC eyebrow window options exist separately and remain interchangeable with the simplified eyebrow design used here.)
Q: Are the Aft Overhead electrical panels in it?
A: Not yet. This document focuses on the structure and the listed forward/auxiliary panels. Aft electrical panels will be handled separately.
Q: What materials do you recommend?
A: The guide provides materials & thicknesses, and costing notes. Typical builds use MDF/ply and square‑stock timber; choose high‑quality sheet goods for cleaner edges and tighter angles.
Q: I’m new to cockpit building—can I follow this?
A: Yes—if you’re comfortable with woodworking basics and have a mitre saw or angle‑cut capability. The guide is written to minimise angle‑stack errors with step‑by‑step checks.
