The ATB teeth cause your joint to be flat at the top. Your best option would be the ripping blade or a blade with a flat top tooth.

  • Armor Tool Bench
  • Table Saw
  • Dado Stack

2.3 Setting up the cut and key.

Put your miter in the space of your table saw and select a piece of wood for a patron. Then, holding the patron against the miter measure, make one cut with your sharp edge.

2.4 Test cuts.

Now set the height of the blade just above the thickness of the wood that will be cut. Therefore, we recommend making a test joint on a piece of wood, similar to what you are doing. 

It’s conceivable that the supporter may require slight acclimations to ensure that the joint is the appropriate fit.

Also, you can make the changes by releasing the screws holding the sponsor to the miter check and making slight moves nearer or further away from the sharp edge. 

To begin the joint’s cuts, place your first board vertically against the patron and the edge flush to the stop and clip it set up. Make the main cut with your hands and fingers securely away from the cutting edge.

Also, at that point, unclamp the board and slide the space you slice onto the stop. Presently you can clasp the board set up and make your subsequent cut. Rehash this cycle until you arrive at the contrary edge of the board.

2.5 The Finger Joint Woodwork– Cutting the joints

As you progress to the tail end of your board, you will most likely have an incomplete cut. At this point, toss your board to face the backer. Hence, slide your first cut into the slot.

Furthermore, take your second board and flush against the first board and clamp it in place to be cut by your blade.

After cutting through both boards, separate the second, slide it against the stop, and then continue to cut until another edge.
