BUTTJOINTS
See Figure 9.
A butt joint is one of the weakest joints in
woodworking. This type of joint is mating the end
grain of one board with the edge grain of another. The
bonding of glue on this type of surface is poor.
However, by using biscuits you can create a stronger
joint that gives a mortise-and-tenon effect.

HOW TO MAKE BUI-I" JOINTS
• Unplug your Detail Biscuit Joiner.
• Place the two pieces of wood to be joined on a
level workbench. Align them against each other in
the arrangement in which they will be assembled.
• Using a square, determine the location of each
biscuit spline joint and mark the center of each joint
by drawing a line across the edges of the two
boards.
• Set fence angle at 90 °.
• Loosen height adjustment knobs, then pull and
slide the fence up or down until the indicator point
is aligned with the desired dimension on the scale.
Remember: The scale indicates the height of the
fence from the center of the blade.
• Tighten height adjustment knobs securely.
• Select the correct depth of cut setting to match the
biscuit size you are planning to use. We suggest
that you make a test cut in a scrap piece of wood
from the same workpiece if possible.
• Clamp workpiece securely so that it will not move
during the cut.
• Plug your Biscuit Joiner into power supply and
prepare to make your first cut. Grasp and hold your
Biscuit Joiner securely with both hands.
• Place the fence against the board and align the
indicator marks on the fence with the centedine
mark(s) on the board.
• Depress the switch trigger and let the motor build
to its maximum speed, then gradually push Biscuit
Joiner forward to extend the blade into the wood.
• When the base assembly bottoms out against the
depth of cut adjustment knob setting, pull back
releasing pressure on the spring. Blade will retract
from biscuit slot.
• Repeat this procedure for cutting the slot in the
mating workpiece.
• Once all biscuit slots have been cut, place a biscuit
in each joint and dry assemble the workpieces.
Make sure each joint lines up and fits.
• Finally, disassemble the workpieces and place a
bead of glue in each slot. Also, spread a bead of
glue over the entire surface of the joint. Reinsert
the biscuits and assemble the workpieces. See
Figure 9.
• Clamp workpieces together until the glue sets up.
OFFSET BUTT JOINTS
See Figure 10.
The rails of a table or workbench are often offset from
the front of the table legs. When offsets are required,
it is necessary to cut the slots in the rails first, then re-
adjust the fence to cut the slots in the legs. m
Keeping this one exception in mind, the procedure for
H
cutting offset butt joints is identical to the procedure
for cutting butt joints.
For example -- If a 1/4 in. offset is desired, you would
mark the centerlines for cutting _'=buttjoint as
mentioned in the procedures for cutting butt joints,
and cut the slots in the ends of the rails. Next you
would raise the fence 1/4 in. to the desired offset and
cut the slots in the legs.
