Tongue and groove joinery has been around for a long time. For those of you that do not have the proper blades, do not think that you are out of luck. There are many different ways to accomplish the same goal and in this video / blog I will show you how.
First, I will show you how to make tongue and groove joinery that will be used for long grain to long grain joints to make large wide panels. Set you fence where the blade is just off center. You will also need a flat bottom grind saw blade to make consistent flat grooves. The blade height will be 3/8” high.
Install a feather board to keep the board up against the fence and keep kickback to a minimum. Make two passes through the blade by flipping the board 180 degrees to center the groove.
Now set up the fence using the groove board as a gauge. The blade will be even with the edge of the groove and the blade height will not change from the last few cuts.
Set the blade height to just clear the left over pieces and set to the depth at the base of the kerf. This will make the shoulders of the tenon as you pass over the blade on both sides.
If necessary, like it was for me, sand you tenon to fit snugly in the groove.
Now I will show you with the use of dado stack how to make the same type of joint on end grain to long grain. Set the blade height back to 3/8” and the fence to off center the work piece. Make your cut once and flip end for end and make another.
Using the groove board as a gauge, lower the blade to the height of the pieces to remove. This will create the shoulders as you pass them over the blade.
It will take a few passes to get the height and depth just right but once you have it set you can make all the batch cuts quickly and easily.
