Y2T2: Equipment Date: LESSON 1 The learner is able to: ➢ Identify, describe and demonstrate the correct use, caring and safety of the following measuring : Measuring Sliding

The sliding T-bevel, also known as a bevel or false is an adjustable gauge for setting and transferring angles. The handle is usually made of or plastic and is connected to a metal with a thumbscrew or wing nut. The blade pivots and can be locked at any angle by loosening or tightening the thumbscrew.

The bevel can be used to duplicate an existing angle or set to a desired angle by using it with any number of other measuring tools, such as a .

QUESTION 1: What is the Sliding bevel used for?

a) ______b) ______

QUESTION 2: Describe the Sliding bevel

______

Y2:T2 Equipment Date: Lesson 2 The learner is ➢ Identify, describe and demonstrate the correct use, caring able to: and safety of the following tools: Measuring

The marking gauge, also known as a scratch gauge, is used in and to mark out lines for . The purpose of the gauge is to scribe a line parallel to a reference edge or surface. It is used in joinery.

The gauge consists of a beam, a headstock, and a scribing or marking implement, typically a pin, or . The headstock slides along the beam and is locked in place by various means: a locking or a . The marking implement is fixed to one end of the beam

QUESTION 1: What is the purpose of the Marking gauge? ______

QUESTION 2: Explain how to use the Marking Gauge

______

QUESTION 3: Name the different parts of the Marking Gauge (Use Google) a) ______b) ______c) ______d) ______e) ______

Y2:T2 Equipment Date: Lesson 3 The learner is able to: ➢ Identify, describe and demonstrate the correct use, caring and safety of the following measuring tools: Measuring Mortise gauge

A mortise gauge is a woodworking used by a or to scribe joints on wood prior to cutting. Mortise gauges are commonly made of with brass fittings.

Like the marking gauge, a mortise gauge has a locking thumb screw slide for adjusting the distance of the scribe from the edge of the wood. It has two protruding pins, often called "spurs", which are designed to scribe parallel lines marking both sides of a mortise at the same time. One of the pins is adjustable, attached to a sliding , so that mortises of different widths can be marked.

QUESTION 1: What is the Mortise gauge used for? ______

Y2:T2 Equipment Date: LESSON 4 The learner is able ➢ Identify, describe and demonstrate the correct use, caring to: and safety of the following measuring tools: Measuring Cutting gauge

Unlike the ordinary marking gauge whose steel scribing pin is designed to mark along the grain, the cutting gauge is equipped with a cutting spur, therefor the cutting gauge carves a neat, clearly visible cut, which assist when cutting

across the grain. The cutting gauge is used to eliminate splintering when crosscutting by scoring the wood prior to sawing.

What is the Cutting gauge used for? ______

Y2:T2 Equipment Date: LESSON 5 The learner is able to: ➢ Identify, describe and demonstrate the correct use, caring and safety of the following cutting tools: Cutting Firmer

A firmer chisel is one of four main used in woodworking projects, to cut grooves with sharp edges into wood. It has a thick, strong blade that allows removal of large pieces of wood in a single strike. The chisel’s blade is strong enough to form deep, large

joints when the end is hit with a . This type of chisel has a bevelled edge

and is a good choice for general woodworking projects. One variation of a firmer chisel is called a bevelled edge chisel, or butt chisel, with on two sides of the cutting surface for more precise trimming.

QUESTION 1: Describe the Firmer chisel

______

QUESTION 2: What is the Firmer chisel used for? ______

QUESTION 3: Label the Chisel (Use Google)

Y2:T2 Equipment Date: LESSON 6 The learner is able ➢ Identify, describe and demonstrate the correct use, to: caring and safety of the following cutting tools:

Cutting Mortise chisel

Mortise chisels are used for ‘chopping out’ joints or chiselling away the waste wood. They are particularly useful for cutting mortise joints as they are strong enough to withstand heavy blows with a mallet. The handle is normally made of wood or

with a steel hoop at the top to stop it splitting. It also has a strengthening piece called a ferrule which prevents the handle from splitting at the bottom when it is hit repeatedly by a mallet. The blade is made from tool steel and the bevel is ground to an angle of 30 degrees.

QUESTION 1: What is the Mortise chisel used for? ______

QUESTION 2: Describe the Mortice Chisel

______

QUESTION 3: Draw the Mortice chisel label it.

Y2:T2 Equipment Date: LESSON 7 The learner is able to: ➢ Identify, describe and demonstrate the correct use, caring and safety of the following cutting tools:

Cutting Paring chisel

Paring chisels are lightweight chisels that are never malleted. They are primarily used for removing thin shavings of wood when one is fitting joints. The thin of paring chisels make them almost flexible. A paring

chisel is long in order to give maximum control to the user. In order for a person to use the paring chisel effectively, one hand is used to push the blades from the handle while the other hand guides the cut that the chisel makes.

QUESTION 1: What is the Paring chisel used for? ______QUESTION 2: Give a description of the Paring chisel

______

Y2:T2 Equipment Date: LESSON 8 The learner is ➢ Identify, describe and demonstrate the correct use, caring able to: and safety of the following cutting tools:

Cutting Gouges chisel

A gouges chisels, serves – particularly in woodworking, and – are used to carve small pieces from the wood and to produce curved surfaces. A gouge chisel typically has a 'U'-shaped cross-section.

QUESTION 1: What is the Gouges chisel used for? ______

QUESTION 2: Name two Gouges

a) ______b) ______

QUESTION 3: Briefly describe what the Gouge chisel looks like

______

______
