Explain groups of wood joint and give 3 types in each group(with neat drawings)?

There are several groups of wood joints, each with its own unique characteristics and applications. Here are three types of wood joints in each group, along with neat drawings:

1. Butt Joints:
- End Butt Joint: This is the simplest type of joint where the end grain of one piece is joined to the face grain of another piece at a right angle.
- Miter Joint: In this joint, the ends of two pieces are cut at a 45-degree angle and joined together to form a 90-degree corner.
- Half Lap Joint: This joint involves removing half the thickness of each piece at the point of intersection, creating a flush and strong joint.


2. Mortise and Tenon Joints:
- Through Mortise and Tenon Joint: This joint involves cutting a rectangular hole (mortise) in one piece and inserting a corresponding projection (tenon) from another piece into it.
- Blind Mortise and Tenon Joint: Similar to the through mortise and tenon joint, but the mortise does not go all the way through the piece, making it invisible from one side.
- Wedged Mortise and Tenon Joint: This joint adds a wedge through the tenon, which expands the tenon inside the mortise, providing extra strength.


3. Dovetail Joints:
- Through Dovetail Joint: This joint is commonly used in drawer construction, where interlocking pins and tails are cut at an angle to create a strong and decorative joint.
- Half-Blind Dovetail Joint: In this joint, the pins are visible only from one side, while the tails are hidden within the wood, providing an aesthetically pleasing appearance.
- Sliding Dovetail Joint: This joint involves a sliding tenon that fits into a corresponding dovetail-shaped mortise, allowing for movement or disassembly.


Please note that the drawings provided are simplified representations of the joints and may not be to scale.
