Answers

A jig is used to make sure that parts are made exactly the same, without the need for marking out. For example, when drilling through a block of wood with two holes in, it will make sure that the holes are drilled in the same place in each component.

A former is used to make sure that parts are shaped or bent to exactly the same shape.

A template is something that you can draw around to mark a shape onto material, so that it can be cut or shaped.

A pattern is used to make a mould when casting in metal or plastic resin. It is a replica of the finished object and may be made in wood or another soft material. Patterns are also used when shaping plastics in a vacuum-forming machine.

A mould is a hollow shape used when casting metal or plastic resin. Moulds for casting metal can be made in a special type of sand, in metal or in plaster. Moulds for casting resin can be made of plaster or rubber.

Video answer: When the layers of veneer are squashed together with a large clamp. The man in the video calls it a mould but the technical word is a former. It forms the shape that is required.
