13. BISCUIT CUTTER/ PLATE JOINER (Porter-Cable 557, Ryobi JM81, Ryobi DBJ50)

(NOTE: Portions of the information presented in this section were taken from the Porter-Cable

Operating Manual.)

This specialized mini-saw cuts thin slots in the edges of wood to hold a biscuit, which is used to hold two

pieces of wood together.

You can use biscuit joinery for a number of different types of

joints. Smaller biscuits work well for strengthening miter joints

and corner joints. Biscuits also work well for T-joints, where the

end grain of one board is connected to the side of another board.

The most common use for biscuits is to edge join boards to make

wider boards.

We have three biscuit cutters in the shop, two full-size and one mini-biscuit cutter. Only one unit is

presented herein, as the principles and general operation and adjustments are similar for all three.

13.1. Safety Precautions

a. Use clamps or other practical way to support the workpiece and secure it to a stable platform.

b. Check for misalignment or binding of moving parts or breakage.

c. Guard against kickback:

• Hold the unit firmly against the project before energizing.

• Make sure the motor is at full speed before plunging.

d. Disconnect the plug from the power source before making any adjustments.

e. Never apply side pressure to slow down a spinning blade.

13.2. Biscuits

A biscuit is a thin, oval-shaped piece of compressed wood shavings, typically made from beech wood.

Biscuits are glued into slots precisely cut by the biscuit cutter, and the moisture from the glue causes the

biscuit to swell and tighten the joint. The Woodshop has biscuits for sale in the cabinets.

Biscuits commonly come in three sizes:

• #0 - 5/8" x 5/8” thick

• #10 - 3/4" x 5/8” thick

• #20 - 1" x 5/8” thick
