Timbers - Tools Equipment and Processes Flashcards
On timbers, what is the face side
The even side
The smooth even edge is called the…………….
Face edge
What is the most popular measuring device
300mm rule, variety of sizes
When using rule or tape measure, you should always make sure that your eyes are over………..
The measurements
Give a popular marking out tool
A pencil
What is an advantage of using a marking knife when marking out on woods
Produces a thin cut line that reduces the tearing and acts as a guide when sawing or chiselling wood
When is a tri-square used
Mark 90˚ lines to a face edge
What is a mitre try-square
Set to 45˚, important when creating a mitre joint in wood
What is a sliding level
Same function as a mitre square, but can be set for any angle.
Useful when marking out more complex angles
What does a template consist of
Profile shape of a part that is to be manufactured
What is a jig
Device that is specially made to perform a specific part of the manufacturing process. Extremely useful when the process has to be carried out multiple times.
Give some advantages of jigs
They speed up the manufacturing process Reduce the risk of error Reduce the unit cost of a part Make the process safer to carry out Increase the accuracy of the process Increase the consist of the process Reduce wastage
Give some disadvantages of jigs
Only cost effective when large numbers of similar parts are required
Increase the initial cost of the product
Require a high level of skill to produce
What is a Hand Saw
Used when cutting thick pieces or large sheets oaf wood. The blade is made from hardened or tempered steel that makes it strong and durable so the teeth remain sharp
Modern handsaws have ‘hardpoint’ teeth, try to keep them sharper for longer
What is a tenon Saw
Used for cutting accurate straight lines in wood and polymers
The blade is made form hardened and tempered steel and the frame is known as a ‘back’ to improve accuracy
What is a Coping Saw
Use for cutting curves in woods and polymers
The blade of the coping saw should face backwards as this keeps the tension when sawing
The design of the saw allows the blades to be quickly and easily changed
What is a scroll saw
Machine version of the coping saw
Allows you to concentrate on the following shapes as the part that you are cutting while the reciprocating blade does all the hard work
This speeds up the process and usually produces a more accurate cut than the coping saw
What is a Jig Saw
every versatile saw as it can be fitted with a wide variety of blades to allow it to saw in different types and thicknesses of manufactured boards
What is a firm chisel
General all purpose chisel that can accept list blows with a mallet
What is a Bevel Edged Chisel
These have edges that are bevelled or angles. This allows the chisel to cut lean accurate corners
This chisel would be used by a cabinet maker when producing a set of hand cut dovetail joints
What is a mortise chisel
Much thicker blade and a leather water inserted between the blade and handle
These two features allow it to be struck much harder with a mallet
e.g to cut a mortise hole in a table leg
What is a plane
Perfect tool for flattening and smoothing the surface or the edges of a piece of wood
A plane works in similar ways to a chisel in that it slices shavings of wood
All planning should be done in the same direction as the grain will tear.
What is a Jack plane
General purpose plane used to flatten and smooth the surfaces and edges of wood
What is a smoothing plane
Used on small wooden parts or the final cleaning of wood surfaces
