Summary:
This video is about making a finger joint jig for the table saw. The jig is made out of wood and has a separate front fence. The author uses a grooving blade to cut the finger joints. The author also provides tips on how to use the jig, such as setting the height of the blade and rotating the workpiece.
Here are the steps on how to make the finger joint jig:
Rip a clean edge on the workpiece at the table saw.
Cut two lengths at the miter saw and two triangle support pieces.
Glue the two panels together to form an L-shaped workpiece and add a few brad nails.
Glue on the triangles to reinforce the workpiece and keep the front panel at 90 degrees to the base panel.
Find a piece of wood to make some runners and rip two pieces down to a couple of millimeters less than the depth of the miter slots.
Rip the runners down to width to fit inside the slots.
Place a few washes at the bottom of the miter slots to lift up the runners higher than the surface of the table.
Offer up a reliable framing square to the blade making sure that it’s not touching any of the carbide teeth.
Apply super glue to the runners and position the main body of the jig at 90 degrees to the blade.
Drill a pilot hole with a countersink to fix the runners in place.
Use a wider bit to drill through the runners to prevent them from splitting when the screws go in.
Add a bit of candle wax to the runners and the base of the jig.
Cut a piece of wood to the size of the blade kerf.
Set the blade height to just under 12 millimeters.
Offer up the front fence and make a cut through it.
Glue the pin in place into the kerf cut.
Trim off a bit from the front fence so it’s the same height as the main body of the jig.
Set up the grooving blade again in the saw.
Use the offcut piece from the curved piece to position the pin on the jig away from the blade.
Clamp the fence in place.
Cut a scrap piece to test how the jig performs.
Glue the workpieces together and cut off the excess and sand everything flush.
