Unit 8 Processing woods Flashcards
What are the categories of timber processes?
Fabrication processes are grouped into categories
Categories include addition, forming, and wasting processes.
What does ‘addition’ refer to in timber processes?
Joining methods
Addition involves techniques to join pieces of timber together.
What is the purpose of forming processes in timber fabrication?
To modify the shape by bending
Forming processes involve altering the shape of timber without removing material.
What do wasting processes do in timber fabrication?
Wear away material
Wasting processes involve removing material to achieve the desired shape.
Fill in the blank: Fabrication processes are grouped into _______.
[categories]
True or False: Addition in timber processes includes removing material.
False
Addition refers to joining methods, not removing material.
What is the purpose of different joints in woodworking?
Different joints are used for different applications.
Can a box or carcass use different joints?
Yes, a box or carcass may use different joints to some framework; some joints are suitable for both.
What factors may affect the choice of joint?
The angle and strength required of the joint may affect the joint choice.
What considerations should be made when making a joint?
The time and skill required to make a joint and the number of times a joint has to be repeated must be considered.
How does the scale of production affect joint choice?
The scale of production may affect the joints used.

Name one traditional joining method.
Comb joint
Name another traditional joining method.
Dovetail joint
Name another traditional joining method.
Housing joint
Name another traditional joining method.
Half-lap joint
Name another traditional joining method.
Dowel joint
Name the last traditional joining method.
Mortise and tenon
What are comb joints used for?
Comb joints are used to form boxes and carcasses.
They are also known as finger joints.
How is a comb joint constructed?
A comb joint is made from interlocking fingers that fit tightly together and are reinforced by glue.
What is the benefit of accurate work with comb joints?
Accurate work can result in a very strong, aesthetically pleasing joint.
What tools are best for creating comb joints?
Comb joints are best created using a router jig on natural or manufactured timbers or using a laser cutter on some materials.
What makes a comb joint stronger than a butt joint?
The interlocking design and reinforcement with glue make comb joints stronger than butt joints.
What is a housing joint commonly used for?
Shelves and dividers
Housing joints provide structural support for items like shelves.
How is a housing joint constructed?
A channel is cut through one piece of timber which houses a second perpendicular piece
This design allows for the integration of two pieces of wood at right angles.
What is a key characteristic of housing joints in terms of strength?
Fairly strong when supported with glue, can be used without glue for sliding parts
The joint’s strength increases significantly with adhesive application.
What is an advantage of making a housing joint?
Only one piece of timber needs to be machined
This simplifies the manufacturing process and reduces material waste.
How could housing joints be affected by shrinkage?
______
Shrinkage could lead to gaps or misalignment in the joint, affecting stability.
What are dovetail joints prized for?
Dovetail joints are prized for their strength and aesthetics.
What are dovetail joints ideal for?
Dovetail joints are ideal for cabinets and drawer construction.
What skill level is required to cut dovetail joints?
Dovetail joints demonstrate a high level of skill but can be cut fairly easily with a router and jig.
What do dovetail joints rely on for strength?
Dovetail joints rely on interlocking fingers and accurate marking and cutting for strength.
What is a unique feature of dovetail joints?
The dovetail shapes mean that these joints have superior directional strength.
Why are dovetail joints excellent for creating drawers?
Dovetail joints are excellent for creating drawers due to their strength and aesthetics.
What is a half-lap joint?
A versatile joining method that is easy to construct.
How is a half-lap joint made?
Made by two overlapping materials glued together.
Where is a half-lap joint commonly used?
Used in picture frames, doors, and cabinet making.
What are the advantages of a half-lap joint?
Quick and easy to make.
What is a disadvantage of a half-lap joint?
Not particularly strong.
What helps resist diagonal distortion in a half-lap joint?
The shoulder.
What components could reinforce a half-lap joint?
Cheek.
What are dowel joints?
Dowel joints are a quick, simple and effective method to join a variety of materials.
Where are dowel joints commonly used?
Dowel joints are used in frame and carcass construction, flat-pack furniture, and to reinforce edge to edge joints.
How are holes for dowel joints created?
Holes are machined easily with a drill, and jigs can be used to speed up the process further.
