GENERAL FOLIOS / B
Methods & associated subjects
Mechanical systems, fabrication, measurement, materials, electronics, and the care of evidence.
REF-001
How to evaluate a technical claim A repeatable method for separating documented facts, inference, prototype results, and marketing.
Methods↗REF-002
Technical drawings that survive handoff Dimensions, datums, units, revision records, and inspection requirements for portable mechanical drawings.
Methods↗REF-003
Tolerances, fits, and stack-ups Why nominally identical parts do not always assemble—and how to reason about variation.
Mechanical systems↗REF-004
Material selection: steel, aluminum, titanium A practical framework for choosing materials beyond marketing claims about “strength.”
Materials↗REF-005
From CAD to part: choosing a process Compare cutting, machining, forming, casting, and additive methods without tying the design to one supplier.
Manufacturing↗REF-006
Designing clean 2D sheet-metal profiles Closed contours, inside radii, layout efficiency, and inspection for flat laser-cut components.
Manufacturing↗REF-007
Additive manufacturing beyond the hype FDM, resin, powder-bed fusion, and binder processes serve very different design goals.
Manufacturing↗REF-008
Sensors, logging, and measurement Build a useful measurement record with timestamps, calibration, and traceable observations.
Electronics↗REF-009
Robotics as systems engineering A high-level architecture for sensing, estimation, control, actuation, and monitoring.
Robotics↗REF-010
Historical technical sources: provenance first How to preserve and evaluate historical manuals without laundering obsolete claims into modern engineering.
History & archives↗REF-011
Versioned knowledge and reproducible editions Git-based chapters, stable citations, review records, correction notices, and build integrity.
Publishing↗REF-012
U.S. technical-data publication and export controls Why publicly posted science, controlled technical data, and machine-ready manufacturing files require different legal treatment.

EDITOR'S NOTE
Every entry separates an established identity from a historical name, a material sample, or an untested claim. The index is a foundation for a much larger work.
