joinery techniques

I wanted to make the base of the little land bigger than the initial prototype where the base was 9*9 inches. I realized that the surface area was too small to build upon. Nikita made an observation at Jaaga where i exhibited little land, she said when kids played with it due to the small surface area, they began asking her to hold the pieces separately around the base, trying to expand the area. So i thought of things:

1. Having a base the size of a small table so kids could sit around and move fix many more pieces and freely move them around.

2. Have 2 or more small bases (maybe 10*10 inches) which can be fixed together to create a larger area. So for this i have been looking at a few joinery techniques:




1. Butt Joint
For this common and simple joint the end of one piece of wood is simply placed against the adjoining piece, forming a right angle. The two pieces can be fastened with screws, glued or dry dowels, or sometimes staples.

2. Box Joint or Finger Joint
Connects two boards at the corners. It is very strong and is often utilized in boxes, such as blanket chests and jewelery boxes, because of its decorative look.

3. Half-lap Joint
It is merely the process of joining two pieces of wood together by removing half of the width from each board so that they completely overlap each other when joined. A very strong and very visually appealing joint.

4. Doweled Joint
It is merely a butt joint that uses wooden dowels to help align and strengthen the bond between two boards. Often times a doweled joint is made into a very visually appealing joint by passing the dowels completely through the side piece and sanding them flush with the surface.

5. Spline Joint
It is achieved by inserting a strip of wood into two corresponding grooves cut into two matching boards. A spline joint is often used to strengthen a butt or miter joint and can add a lot of visual appeal by using contrasting colors of woods.

6. Doweled Joint
It is merely a butt joint that uses wooden dowels to help align and strengthen the bond between two boards. Often times a doweled joint is made into a very visually appealing joint by passing the dowels completely through the side piece and sanding them flush with the surface.

7. Rabbet and Dado Joints
These are simple joints that create an incredibly strong bond by inserting one piece of wood into a groove or channel in another piece of wood. This joint is the backbone of cabinet box and bookcase construction.

8. Raised Panel Joint or Frame and Panel Joint
It is the primary method of constructing cabinet doors. Each panel consists of two vertical stiles running the complete height of the door, two rails that run the overall width of the door minus the width of the two stiles, and a center panel. This joinery technique creates a large panel that is unaffected by environmental changes, because the center panel floats between the rails and stiles, and is able to expand and contract without affecting the other pieces. There are hundreds of different router details that can be used on the rails, stiles, and doors, to create a look as fancy or as simple as desired.

9. Mortise and Tenon Joint
It is one of the strongest and most widely used joinery methods in woodworking. The joint is simple, it merely attaches two pieces by inserting a tenon into a mortise, but there are a multitude of applications and variations that are employed throughout woodworking. This joint is a staple in the building of chairs, tables, cabinet doors, and paneling.

10. Miter Joint
It is a simple and easy way to connect any two pieces of wood together at any angle necessary. Simply cut each edge to half the overall angle and join together using glue, nails, or screws. The miter joint, like the butt joint, is not very strong, but is quick and simple to make.
