biscuitdowels

Biscuitdowels are a type of fastener used in woodworking and furniture construction. They are typically made of compressed wood fibers, shaped into small, flat discs, resembling biscuits or cookies. These dowels are inserted into pre-cut slots in the edges of two pieces of wood that are to be joined. Wood glue is applied to the slots and the dowel before insertion. When the glue cures, the biscuitdowels absorb moisture from the glue and expand, creating a tight and secure bond.

The primary advantage of using biscuitdowels is their ability to provide alignment and reinforcement to glued joints. They help prevent the pieces from shifting during the clamping process, ensuring a flush and accurate fit. This is particularly useful for edge-to-edge joints, miter joints, and butt joints. Biscuitdowels are inserted using a biscuit joiner, a specialized power tool that cuts the necessary slots. The process is generally quicker and less complex than traditional joinery methods like mortise and tenon.

Biscuitdowels come in various sizes, designated by numbers such as #0, #10, and #20, which correspond to the size of the slot they are designed to fit. The choice of size depends on the thickness and type of wood being joined. While effective for many applications, biscuitdowels are not considered as strong as mechanical fasteners like screws or bolts, and their strength can be compromised if exposed to excessive moisture after the glue has cured. They are most commonly used in interior furniture and cabinetry where extreme structural loads are not anticipated.
