A micrometer
How do we make sure our work is secure while we are marking out?
A vice
What is a marking knife used for?
Torsai K
A marking knife is used in preference to, or with a pencil. This gives other tools like chisels to locate when working.
Purpose of a marking gauge.

Purpose of a mortice gauge.
Torsai K
As per the marking gauge but with two adjustable pins to mark out a mortise joint.
What are Datum edges?
Torsai K
Marked out faces of the flattest surfaces. They should be worked on and free of defects
What do you use a surface plate for?
Torsai K
The surface is ground to a high degree of accuracy and provides a datum surface against which measurements can be taken.
