Summary:
This video is about how to make finger joints on the table saw.
In the beginning of the video, the author mentions that they are going to be making drawers for their next project and finger joints are a really strong way to join the wood together. So they decided to make a simple finger joint jig.
Here are the steps on how to make the finger joint jig:
First, figure out how wide your blade kerf is by doing a stop cut on the table saw and then measuring it with calipers.
Next, rip a piece of plywood that will be the main part of the jig.
Attach the pin to the piece of plywood using CA glue and accelerator spray.
Now you need to find the perfect distance between the pin and the blade. To do this, place the cut off from the strip that you cut earlier in between the pin and the blade. Once you are happy with the placement, adjust your stop loss and clamp it down.
To use the jig, take your piece and place it next to the pin on the jig, clamp it down and run it along the saw.
Now that you have made the first cut, you need to flip the first piece around and place the first cut that you made over the pin on the jig. Then you need to put the second piece next to it in order to make the first cut. This creates a gap instead of a pin for your first cut.
Clamp it down and cut the joints the way that you did on the first piece by just placing each piece on the pin as you go until you can't cut any further.
After you are done cutting the joints, glue them together and assemble your project.
The author mentioned that they used a flat tooth blade and recommends using one if you want the joint to look as clean as possible. They also said that they set the blade to be slightly higher than the material because sanding away the excess is way better than not cutting the joints deep enough.
