Beams are used to construct floors, ceilings, and roofs. In a house frame, for example, beams hold up the floor and roof structures, ensuring they remain level and sturdy.

2. Joist

A joist is a horizontal support that runs parallel to the beams and supports the load of the floor or ceiling. It’s commonly made of wood, steel, or engineered materials and is spaced evenly to provide a stable framework.

Joists support floorboards in a flooring system, maintaining the floor’s structural integrity and preventing sagging.

3. Stud

A stud is a vertical framing member within a wall that helps support the structure. Studs are usually made of wood or metal and form a framework to which drywall or other wall materials are attached.

Studs provide a secure frame for attaching drywall, insulation, and other materials. They are installed at regular intervals to ensure the wall can support doors, windows, and fixtures.

4. Plumb

Plumb refers to an object’s vertical alignment. If something is plumb, it means it is perfectly vertical or perpendicular to the ground, ensuring the structure is balanced and straight.

Carpenters frequently check if walls, posts, and beams are plumb during construction to ensure proper installation, such as when hanging a door frame.

5. Level

Level refers to an object’s horizontal alignment. If something is level, it is perfectly parallel to the ground, ensuring even surfaces like floors, countertops, and shelves.

Carpenters use levels to ensure surfaces are perfectly horizontal. For instance, when installing kitchen cabinets, checking for level ensures the cabinets sit evenly, preventing items from rolling off.

6. Miter

A miter is an angled cut made across the face of a material, typically used to create corners in trim or molding where two pieces need to join at an angle.

Carpenters use miter cuts when installing crown molding or baseboards to ensure the pieces fit together seamlessly at corners, resulting in a clean finish.

7. Rafter

Rafters are the sloped framing members of a roof. They run from the ridge (the peak of the roof) down to the eaves, supporting the roof deck and covering materials.

When constructing a building’s roof, carpenters install rafters to create the roof’s slope and support materials like shingles or tiles.

8. Header

A header is a beam placed above an opening, such as a door or window, to support the weight of the structure above it and distribute the load to the surrounding studs.

Headers ensure that door and window openings remain structurally sound, preventing sagging and ensuring smooth operation.

9. Fascia

The fascia is a horizontal board that runs along the edge of the roof, covering the ends of the rafters. It serves both a protective and aesthetic function, often supporting gutters.

Properly installed fascia protects the roof’s edge from weather damage and provides a place to secure gutters, adding to the building’s overall appearance and durability.

10. Lap Joint

A lap joint is created by overlapping two pieces of wood and securing them together, typically with glue, nails, or screws. It’s often used where strength is required.

In frame construction, lap joints connect the corners of wooden frames, providing a strong and durable connection for walls, windows, and doors.

When installing a countertop against an uneven wall, carpenters use a scribing tool to mark the exact contour of the wall onto the countertop, ensuring a seamless fit.

6. Chamfer

A chamfer is an angled cut made along the edge or corner of a piece of wood, usually at a 45-degree angle. It removes the sharp edge for both aesthetic and safety purposes.

Chamfers are often added to table edges to soften the corners, improving the look and preventing injuries from sharp edges.

7. Kerf

The kerf is the width of the cut made by a saw blade. It’s crucial to account for the kerf when making precise cuts to ensure that the pieces fit together as intended.

When cutting wood for framing, carpenters must account for the kerf of the saw blade to avoid ending up with pieces that are too short.

8. Scarf Joint

A scarf joint is a method of joining two pieces of wood end-to-end to create a longer piece. The ends of the wood are cut at complementary angles and then joined together, often using glue or fasteners.

In trim work like baseboards or crown molding, carpenters use scarf joints to splice two pieces together seamlessly when a single piece isn’t long enough.

9. Coping

Coping is a technique used to join two pieces of molding at a corner, ensuring a tight fit. One piece is cut to fit the profile of the other, allowing them to join seamlessly.

When installing crown molding, carpenters cope one piece to match the profile of the adjacent molding, creating a perfect corner joint.

10. Miter Box

A miter box is a tool that helps carpenters make precise miter cuts by guiding the saw at specific angles, usually 45 or 90 degrees.
