|INITIAL PREPARATION OF TIMBER|
|V. Ryan © 2011|
ROUGH SAWN TIMBER:
|When wood is cut to a basic size on a
circular saw, it is called ‘rough sawn’. The edges and sides are not
smooth. This is usually the first stage of preparing wood for further,
more accurate work.
Wood can be purchased rough sawn or planed. Rough sawn timber is cheaper. Rough sawn wood is often used on building sites, where the wood surface finish is not critical or not likely to be seen. A company / business that has a machine planer may buy rough sawn boards and plane them to size themselves, saving money.
|Wood boards are normally planed on a
planer / thicknesser (sometimes called a combination planer).
This prepares the wood by planing the edges and sides accurately, smoothing surfaces. This type of machine can be used to ‘square’ edges, so that they are straight and level.
Planed wood is purchased by companies who do not possess a machine planer or find it is cheaper or more convenient for timer to arrive on their premises, planed and ready to use.
Planed timer is more expensive than rough sawn.
