What Is a Biscuit Joiner

Woodworkers know that there are numerous methods to signing up with two pieces of wood together. On other occasions you might select to make the joinery itself a showcase portion of the task, in which case you might choose the classic beauty and proportion of dovetails or finger joints.

A biscuit joiner (or in some cases plate joiner) is a woodworking tool utilized to join 2 pieces of wood together. A biscuit joiner uses a small circular saw blade to cut a crescent-shaped hole (called the mouth) in the opposite edges of 2 pieces of wood or wood composite panels.

The biscuit joiner is among those tools that guarantees to make life so much simpler. The capability to make relatively strong joints rapidly and quickly makes this a tool you actually must have. Yet numerous woodworkers discover it aggravating; for some factor the joints never quite line up and in the end it does not seem to save that much time.

It isn’t really the fault of the tool. The fact is that most woodworkers don’t know the best strategies to make one of the most of their biscuit joiners, and there are some common attitudes and presumptions that hurt more than assistance, and don’t speed things up.

The biscuit joiner was initially developed in the late 1950s by Herman Steiner. The Swiss cabinetmaker was searching for a better method to put together the cabinets he was making from the freshly introduced particle board. Since of the way particleboard was manufactured, the joinery strategies in usage at the time with strong wood panels were not appropriate for this brand-new product. Steiner presented the very first portable plate joiner, under the name Lamello, in 1968. The patent defense for the Lamello has long since ended and now several producers offer biscuit joiners as part of their woodworking tool line.

A biscuit joiner (or plate joiner) is developed to assist in the assembly of manufactured panels in cabinet carcass building. Glue is used to the grooves, an oval shaped ‘biscuit’ (plate) is placed into the groove, and the 2 pieces are secured together. As the biscuit takes in wetness it broadens slightly to fill the grove.

The wooden biscuits that serve to link two pieces of sheet goods together are all 4mm (5⁄32″) thick, and come in 3 basic sizes: # 0, # 10 and # 20. These are made from a wood, typically beech, which has actually been dried and then compressed in a press. When in contact with glue the biscuits takes in the water to broaden somewhat and fill the area in the biscuit groove. Since all manufacturers utilize the exact same size blade to cut the biscuit grooves, biscuits are interchangeable from model to design; what will separate one biscuit joiner from another is the fence. Nevertheless, not all biscuits are alike. Some brands seem to have a great deal of variation in biscuit thickness; sometimes the biscuits are hard to place in the grooves, and at other times they are too loose. Preferably you desire a biscuit that fits inside the groove comfortably. It’s a great idea to keep your biscuits sealed in a plastic bag or container when not in usage.
