Wood & Materials

The material is the constraint. Every design starts with what the wood wants to do. Species, grades, sheet goods, movement, hardware, and adhesives.

66 guides · 10 subtopics

Wood is the material and the constraint. Every design decision, every technique, every finish choice starts with understanding what the wood wants to do — and the boards on your bench are rarely as flat, as straight, or as dry as they look. Oak moves differently than maple, pine takes finish differently than walnut, cherry darkens with sunlight, and poplar doesn't.

The two decisions that shape every project are the same two decisions every time: which species, and which sheet goods, hardware, and adhesives go with it. Species pick locks in hardness, figure, finishing behavior, and cost; the supporting materials lock in how the assembled piece holds together over years and seasons. Get those two right and the rest of woodworking is craft. Get them wrong and no amount of joinery saves the project.

The guides below cover species identification, grain and figure terminology, moisture and movement math, lumber grading, sheet goods selection, and the hardware and adhesives that hold everything else together.
