Study guide – concise, organized, and easy to read
1. What Is Carpentry?
| Aspect |
Description |
| Definition |
The trade of shaping, cutting, and assembling wood (and sometimes other materials) to create structures, fixtures, and furniture. |

2. What Is Joinery?
| Aspect |
Description |
| Definition |
A specialized branch of carpentry that concentrates on making precise, often decorative, wood connections without relying on metal fasteners. |
| Typical Products |
Cabinets, doors, staircases, furniture, window frames, mouldings, and other interior woodwork. |
| Work Setting |
Mostly shop‑based (bench work) but also on‑site for custom installations. |
| Core Competencies |
Fine‑cut joinery (mortise‑and‑tenon, dovetail, finger‑joint), surface finishing, accurate layout, and use of specialized hand and power tools. |
3. Common Materials
| Material |
Characteristics |
Typical Uses |
| Softwoods (e.g., pine, spruce, fir) |
Light, easy to cut, inexpensive; prone to denting & warping. |
Framing, sheathing, basic interior trim. |
| Hardwoods (e.g., oak, maple, walnut, cherry) |
Dense, strong, stable; takes finish well. |
Furniture, cabinetry, decorative trim, stair treads. |
| Engineered Wood (plywood, MDF, particleboard, LVL) |
Consistent dimensions, reduced waste, good for large panels. |
Sheathing, cabinet boxes, sub‑floors, interior walls. |
| Composite & Plastic (PVC, uPVC, composite decking) |
Moisture‑resistant, low maintenance. |
Exterior trim, window frames, decking. |
