OPERATION (cont.)
•
Repeat this procedure for all desired biscuit slots.
•
Once all biscuit slots have been cut, place a biscuit in each joint and dry
assemble the work pieces. Make sure each joint lines up and fits.
•
Finally, disassemble the work pieces 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 work pieces.
•
Clamp work pieces together until the glue sets.
Offset Butt Joints
The rails of a table or work bench 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 and then
re-adjust the fence to cut the slots in the legs.
Keeping this in mind, the procedure for cutting offset butt joints is identical to the
procedure for cutting butt joints.
For example – If a 6mm offset is desired, you would mark the centerlines for
cutting a butt joint 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 6mm to the
desired offset and cut the slots in the legs.
T – Joints
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 center lines, mark the intersection points for each slot and
cut each slot correctly.
How to Make T – Joints
Unplug your 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 as shown. The centerlines for both boards must line up with each other.
Measure carefully; these measurements must be accurate and precise. Tip:
Measure twice and cut once. In addition to the centerlines lining up, the
spacing of the biscuit slots from side to side must also match.
•
Plug your biscuit joiner into the power supply and cut slots in all boards that
require end slots. Follow procedures explained in Edge-to-Edge Joints. Set
fence angle at 0º, set fence height at desired dimension on the scale, select
the correct depth of cut setting for the biscuit size you plan to use, clamp work
pieces securely, then cut each slot at the marked centerline intersection.
•
Next, you must adjust the fence on your biscuit joiner in order to cut slots into
the face of the vertical board.
