Batch production Tools
Jig
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.
Former
A former is used to make sure that parts are shaped or bent to exactly the same shape
Template
A template is something that you can draw around to mark a shape onto material, so that it can be cut or shaped.
Pattern
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.
Mould
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.
Materials
Timber
There are two types of timber, called hardwood and softwood. These names do not refer to the properties of the wood: some softwoods can be hard and some hardwoods can be soft.
Softwood
Softwoods come from coniferous trees which are evergreen, needle-leaved, cone-bearing trees, such as cedar, fir and pine.
Hardwood
Hardwoods come from broad-leaved, deciduous trees. The main hardwood timbers are ash, beech, birch, cherry, elm, iroko, mahogany, meranti, oak, obeche, sapele and teak.
