Wood and furniture: joiner basics

The joiner works with wood: solid (oak, beech, spruce), boards (chipboard — cheap, for carcasses), MDF (smooth — for painting). Joints: screws+dowels, wood glue (PVA — stronger than wood), groove+tongue (classic), lamellos. Saws: circular saw, jigsaw (curves), handsaw. The rule: "never toward you, always away".

• ●Wood moisture ~8–12% for furniture: wet wood warps indoors
• ●Wood glue fills the joint and holds stronger than wood — but not metal
• ●Sand along the grain: across leaves scratches forever
