	INTRODUCTION

Spline joinery is one of the strongest methods of joinery used in woodworking. When glue is properly applied to a spline and to the joint area of the wood pieces being connected, a large surface area receives the adhesion properties of the glue. This forms a very strong joint.

Traditional spline joinery requires cutting slots with a router or table saw. Small, thin strips of wood must then be cut to fit inside the slots and act as splines.

Newer methods of spline joinery use a plate or biscuit joiner to cut precise mating oval slots in adjoining boards. Your new biscuit joiner is a fast, simple, and accurate plunge cutting tool that can be used for this purpose. It can be used to cut slots in hardwood, softwood, plywood, par- ticle board, and other pressed woods.

Football shaped wafers, called biscuits, are then placed inside the slots with glue and used to help line up adjoining surfaces. When a water based glue is used, the biscuits swell in the joint, making an extremely strong and firm bond. White glue, yellow glue, carpenters glue, hide glue, and aliphatic resin glue are examples of water based glues.

This bonding technique has traditionally been limited to making edge-to-edge joints. However, with the use of your new biscuit joiner, biscuits can now be easily used to connect butt, miter, and T-joints. Biscuit joining can be as strong as mortise and tenon, tongue and groove, standard spline, and doweled joints. In most cases the material around the biscuit will break before the biscuit itself will break. A greater surface area is exposed to glue in a biscuit joint, making the seams stronger.

WARNING:

WEAR YOUR

SAFETY GLASSES

FORESIGHT IS BETTER

THAN NO SIGHT

The operation of any biscuit joiner can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power tool operation, always wear safety goggles or safety glasses with side shields and a full face shield when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses with side shields.
