- 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!
