Tech program: Carpentry
Carpentry is the skilled trade and craft of cutting, shaping, and assembling wood and other building materials to construct, install, and repair structures or objects.In the third picture you will see a tool used for biscuit joining. A biscuit joiner is a specialized woodworking power tool that uses a small, spinning saw blade to cut matching crescent-shaped slots into the edges of wood or composite panels.How It Works & Primary PurposeAlignment over Strength: The tool is primarily designed for rapid edge-to-edge alignment (such as panel glue-ups, table tops, and face frames) rather than heavy load-bearing structural support. The glue does most of the heavy lifting, while the wood biscuit keeps the boards flush.The Biscuit: Compressed, oval-shaped wooden discs (typically beech) are inserted into the glue-filled slots. When glue touches the compressed biscuit, it swells up to lock tightly into the wood.Standard Sizes: Biscuits typically come in sizes #0, #10, and #20 (with #20 being the largest and most common), along with specialized sizes for hinges or smaller frames.Play Room: The slots cut by the joiner are slightly wider than the biscuits themselves, allowing minor side-to-side adjustments before the glue cures.
