Dado Blades – Two Type

Dado blades there are two type

1. WOBBLE DADO BLADE

With an offset spin, the wobbling dado blade is a single blade. It sways while cutting to form a "S" pattern within the plate width; you may alter this pattern to get the appropriate cut width even though it doesn't "wobble." These plates rotate, giving you the ability to customize the cut by adjusting the amount of lead on the blade.

2. STACKED DADO BLADE

A stack of blades is used to form a broader blade, which is known as a stacked dado blade. Spacers can be used between these blades to get an exact cut. Depending on the thickness of your cut, chipper blades can be added or deleted from the area outside the outer blades. The chippers also establish the cut's length. Because of their great performance and adaptability, stacked dado blades are favored by woodworkers.

Sizes Of Dado Blades

Typically, the dado set's outer blades measure 8 inches in diameter and 1/8 inch in thickness. The thickness of the chippers is 1 3/32, 1 1/16, and 4 1/8 inches. There are almost infinite alternatives for width because of this range of sizes. About an inch is the largest width that may be achieved, and practically any measurement below that can be met. Dado blades with an 8-inch diameter are designed to be used with a 10-inch saw since they are not meant for thorough cuts. Additionally, blades with diameters of 6 and 7 inches are available.

HOW DADO BLADES WORK

Dado blades are made up of three basic parts: spacers (sometimes called shims), chippers, and outer blades. The neat edges of the cuts are made by the outer blades. The waste is removed by the chippers, which are positioned in between the outer blades. Additionally, the shims aid in precisely adjusting the desired cut's breadth. Dado blades have the major benefit of having flexible widths and a flat bottomed cut. This allows you to quickly make really exact cuts, which has amazing joinery applications. Dado blades are incredibly versatile, quick, and accurate tools that are useful for both novice and expert woodworkers.

JOINT TYPES

Dado blades may be used to create four distinct sorts of joints.

1. DADO AND GROOVE

The groove joint runs with the grain, while the dado joint is a three-sided canal that crosses the wood's grain. The three sides increase the surface. Area available for glue binding while producing a strong connection with exceptional shear resistance.

2. RABBET

The dado cut or groove along the wood's edge or end of a rabbet joint ensures that the long side of the second piece of wood fits flush into the groove when it is fitted into it.

3. TONGUE AND GROOVE

The tongue component protrudes from the board and slides into the groove cut of another board, creating a flat surface. This joint is strong for edge-to-edge joints and allows the wood to contract and expand.

4. HALF LAP

Where the wood overlaps and is cut away, a half lap joint has roughly half the thickness of each piece of wood. After that, the wood pieces are connected to form a single, flat piece. Half lap joints are robust joints with a lot of surface area for glue bonding.

BRIDLE JOINTS WITH DADO BLADES

Dado blades also demonstrate their accuracy and adaptability at bridle joints. A tenon on one piece fits into an open-ended mortise on another in this kind of joint. They're employed in many different projects, such as the elaborate designs. I created for this Infinity Cube Table, as well as in the construction of frames and table and chair legs. Dado blades let you to precisely cut the mortise and tenon for a precise and snug fit without requiring significant setup adjustments. Use a bridle joint jig that slides along the table saw fence to hold the workpiece stationary. As you make the cuts. To get safer and more accurate outcomes, always remember to make incremental passes for deeper cuts. Even inexperienced woodworkers may safely cut these joints using a dado blade, creating a plethora of new woodworking opportunities.
