shining into the operator’s eyes.

11.2 Table saws

Chapter 11: Woodworking machines

Aims and objectives

At the end of these activity sheets, you should be able to:

detail the different operations carried out by a table saw

state all the parts of a table saw

show an understanding of the tooling on a table saw, and how to change it

calculate the peripheral speed of a saw blade

understand the theory behind the set up and safe use of a table saw.

1 Correctly label the following photo.

2 Draw lines to join the parts of a saw blade to the correct definitions.

hook the distance between two teeth

pitch the angle at the front of the tooth. A positive hook is

required for ripping, with an angle of 20–25 degrees for

softwoods and 10–15 degrees for hardwood

top ensures that the heel clears the timber when cutting

kerf the angle across the top of the tooth

clearance the amount each tooth is sprung out to give clearance

angle and prevent the saw from binding

gullet the space between two teeth, which carries away

the sawdust

set the width of the saw cut (not the width of the blade)

3 Calculate the rim/peripheral speed of a saw blade with a diameter of 650mm and a spindle
