Key ideas in Building Your First Cabinet
- A butt joint is formed when two boards meet without any interlocking notches or grooves
- Wood glue creates a bond stronger than the wood itself once cured
- The boards meet at a 90-degree angle
- Screws provide the necessary pressure to hold the boards together while the glue sets
- It is the most basic method for connecting two pieces of lumber
- Mechanical fasteners act as 'internal clamps' during the drying process
- Recognizing the structure and application of a butt joint
- Understanding the roles of glue and screws in a joint
- Screws displace wood fibers, creating outward pressure that can split the board
- Pre-drilling a hole slightly smaller than the screw removes material to make room for the threads
- Splitting is most common when fastening near the end of a board
- Pocket holes are drilled at an angle to hide the screw head on the underside or inside of a project
- They eliminate the need for visible screw heads or wood filler on the 'show' side of the piece
- They allow for strong face-frame construction without specialized clamps
- Identifying the benefits and use cases for pocket hole joinery
- The cut end of a board (end grain) is highly porous
