T- JOINTS
See Figure 13.
A T-joint is used when the end of a board is joined to the face
of another board. Attaching shelves to bookcases and inner
support braces to frames are typical applications. Actual
cutting of a T-joint is as simple as any other cut. However, it
is critical that you mark the centerlines, mark the intersection
points for each slot, and cut each slot correctly.

• Unplug the biscuit joiner.
• Place the two pieces of wood to be joined on a level
workbench. The inside face of the vertical board
should be facing up.
• Determine the location of each biscuit joint and mark
the centerlines on each board. The centerlines for both
boards must line up with each other. Measure carefully;
these measurements must be accurate and precise.
NOTE: Measure twice and cut once. In addition to the
centedines lining up, the spacing of the biscuit slots
from side-to-side must also match.
• Plug the biscuit joiner into the power supply and cut
slots in all boards that require end slots.
Follow the procedures explained in "Edge-To-Edge
Joints."
• Set the fence angle at 90 °
• Set the fence height at the desired dimension on the
scale.
• Select the correct depth of cut setting for the biscuit
size you plan to use.
• Clamp the workpiece securely, then cut each slot at
the marked centerline intersection.
Next, you must adjust the fence on the biscuit joiner in
order to cut slots into the face of the vertical board.
