How to Use Biscuit Joints

Biscuit Joints are Ideal for Connecting Face Frames or Table Top Glue-Ups

Biscuits are small football-shaped pieces of pressed wood, most commonly made from beechwood. This type of wood is used because the beechwood has a tendency to swell when moisture is applied, allowing it to fill in gaps and provide a strong hold. The principle is similar to how wood grabs onto a nail when it is driven through two boards, allowing the joint to remain tight.

A biscuit cutter (sometimes referred to as a plate joiner) is used to cut slots in the two adjoining boards, into which the...MORE biscuit is glued. Biscuits don't have a lot of pull strength, but are provide considerable lateral strength. This makes them ideal for table top glue-ups, attaching face frames to cabinets or book shelves and more. Learn some tips for using biscuit joinery in your woodworking projects, plus some free woodworking plans that prominently feature biscuits.
