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.
INTRODUCTION
Look for this symbol to point out important safety precautions.
It means attention!!! Your safety is involved.
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.
