They also allow a bit of wiggle room laterally, which is something you don’t get from tenons or dowels. Since the biscuit jointer cuts the slots at consistent heights, the biscuits themselves help align the boards during glue-up. The most common use for a biscuit joint is mating edge grain to edge grain, like when making a tabletop from several pieces of wood. Common Types of Biscuit Jointsīiscuit joints get a bit of criticism for their strength (or relative lack thereof), but there are quite a few applications where biscuit joints are ideal. With wood spread along the edges of the boards, the biscuits will align them to make a very flat surface that requires just a bit of sanding. After clamping a straight edge in place, they’ll be able to bore the slots in seconds.įor tabletops, biscuit joints between boards are much faster than milling tongue-and-groove joints on a router table. By aligning the side of the cabinet and drawing reference lines across both boards, they can mark the locations for the biscuits. The tools to make a biscuit join are easy to use and achieve consistent results.įor instance, if someone is building a bookshelf, they could easily layout consistent and parallel shelves using a biscuit joiner. When to use a biscuit jointīiscuit joints are ideal when ease, speed, and consistency are more important than strength. This also allows the user to cut double biscuits when extra strength is necessary.

By twisting the dial, the user can adjust the height and cut consistent slots against materials of the same thicknesses.

The user simply twists the knob to the correct depth (which is usually marked on the biscuit jointer), and the machine will automatically limit the blade’s travel at the correct depth, which allows for a tight fit and solid joint.īiscuit jointers have adjustable fences that register against the board and control the height of the slot. The most common sizes are:īiscuit joiners also have depth settings to accommodate these biscuit sizes. The general rule of thumb is to use the largest biscuit possible, as larger biscuits allow for more surface area for glue. This allows the user to install a biscuit joint in wood of all types and thicknesses. The biscuits themselves come in a few different sizes, with varying lengths and widths. $75.00 USD | 1H 58M Preview Course Biscuit Joint Sizes and Settings
