What is joinery? In our case we will be looking at the fastening or combining of two or more boards together when building our projects. It is important to have good, strong joints when building furniture. It is sometimes good to use both advanced joinery methods and fasteners when assembling the project.

Slide 3

Used to join 2 boards Edge to edge End to side End to edge Very simple form of joinery

Slide 4

Slot or groove is cut across the width of a board (on the inside) when joining 2 boards together Boards are joined at right angles to one another Remove a portion from one board to accept the other board (usually half the thickness of your material)

Slide 5

Similar to a dado joint Remove material from the end or edge of a board Makes the boards connect at a right angle to one another

Slide 6

The spline is the strip of wood used in the center of this joint. The spline is inserted into matching grooves/troughs on two boards. Splines are often used to reinforce miter or butt joints. Spline can also help align the pieces for the glue-up procedure. You can also use a spline joint as a decorative accent in your project.

Slide 7

The division, into 2 equal parts, of an overall angle created by 2 intersecting parts Most frames that use miter joints meet at 90 so the two pieces are cut at 45 Precise cuts are very important you will see gaps and have a less secure joint if your cuts are not accurate

Slide 8

Remove the full width of the intersecting wood pieces. The two parts meet and together make up the entire thickness. Should be used with fasteners as well in order to increase the strength of the joint.

Slide 9

A short tongue is cut along one edge. A matching groove is cut along the edge of the other board. Good to use when making a wider panel from narrow boards.

Slide 10

Cut straight slots and grooves out of the end of two boards in order to form an interlocking system at the corners. Sometimes referred to as a finger joint. Used for decorative reasons as well as to strengthen the assembly.

Slide 11

Join two pieces of wood at an angle (usually 90) A tenon (a portion that sticks out) is cut on the end of one board. A matching recess, slot or hole is cut into the other piece (mortise). The two fit together to make a strong joint that is frequently used in furniture making.

Slide 12

A system of pins and tails that interlock together. Tails are the triangular shape cut through the thickness of a board. Pins are more slender portions cut along the grain of the other board. One of the strongest joints. Also very attractive for of joinery.

Slide 13

Cylindrical piece of wood used to join two pieces of wood together. Holes are drilled into both pieces of wood at precise locations. The dowel (cylindrical piece) fits into the hole on either side. Makes a butt joint more secure.

Slide 14

Thin football shaped disk is used to join two boards together. A slot is cut into each board. The biscuit fits halfway into each side of the slot. The biscuit expands with the glue to fill the gap.

Slide 15

What are the different types of fasteners?

Slide 16

Define the term fastener as it would be used in the woodshop. Choose 3-4 specific types of fasteners (ie. Glue, nails, screws, tape, etc.) and describe its benefits. For example Robertson screw, Gorilla Glue, and roofing nails Why would we use waterproof glue over regular wood glue. Why do some nails have twists along the shank? Do not write a novel but make sure you have enough information about each. If you would prefer to do a PowerPoint over a Word document then do so!
