This variety reflects the range of products that can be made from timber. The processes used for wood are cutting, drilling, sanding, chiselling and planing. ### Sanding ![Sanding](https://image-v2.cdn.app.senecalearning.com/2019-04/e4ae74ca-7151-42c1-8079-2562eca4b498/sandpaper-.jpg) - Sanding can come in a paper form or a machine form. - You can use sandpaper or a sanding block. - To sand something you rub a gritty abrasive paper on the surface of a material to reduce its dimensions or to enhance its finish (usually to smooth it). ### Sandpaper ![Sandpaper](https://image-v2.cdn.app.senecalearning.com/2019-04/66d23a20-d649-4bd3-a974-b9da3e2783d5/sandpaper-dt-.jpg) - Sandpaper comes in many levels. - It varies from 60-400 grit. - The higher the number the smoother and less abrasive the paper is. - It is usual to start with a lower grit and work to a higher grit so that you achieve a full smooth finish. ### Sanding wood ![Sanding wood](https://image-v2.cdn.app.senecalearning.com/2019-04/193416fe-dafa-4a1b-8fec-0fddb38e6c7c/belt-sander-.jpg) - Prepare the wood and ensure that the surface is clean and free from dirt. - Ensure you work evenly and in a circular or linear motion. - A rotary or belt sander can be used to speed this process up. - It is important to use an extractor fan or a dust mask to prevent inhaling dust particles. ## Planing The planer is used to shave away wood so that it is smoother, flatter and improved in terms of shape or the thickness reduced. ### Planing ![Planing](https://image-v2.cdn.app.senecalearning.com/2019-04/3a323f48-0fc2-4090-b45c-eb70b22115b0/planer-wood-.jpg) - Planing can be achieved through: - A bench plane. - A router plane. - An electric planer. - A thicknesser. ### Using a planer ![Using a planer](https://image-v2.cdn.app.senecalearning.com/2019-04/07dcb79a-61ba-488e-9a6a-0fae93ed930a/planer-carpenter-wood-.jpg) - The planer is used to shave away wood so that it is smoother, flatter and improved in terms of shape or the thickness reduced. - The 45-degree angle on the planer can be adjusted so that more wood can be shaved off. - Often you will plane a rough sawn piece of wood to square it off. ### Using a thicknesser ![Using a thicknesser](https://image-v2.cdn.app.senecalearning.com/2019-04/89a5b612-91bf-4c85-b9a5-19e593d988ee/Thicknesser-wood-.jpg) - A thicknesser easily reduces the thickness of the wood and ensure that the wood is ready to use. - Once timber has been laminated side by side you can use a thicknesser to make a furniture board. ### Using a chisel ![Using a chisel](https://image-v2.cdn.app.senecalearning.com/2019-04/9848d019-31cf-4843-a83f-da9de3259936/chisel-tool-.jpg) - A chisel is made up of a steel blade that has a handle on one side and a sharp blade that is honed on the other. - The angle of the blade is usually 30 degrees and is used for cutting shapes and patterns out of wood. ### Using a chisel cont. ![Using a chisel cont.](https://image-v2.cdn.app.senecalearning.com/2019-04/a2ba3887-46f7-41b9-b6cf-d046f8304e89/chisel-tool-dt-.jpg) - Using a mallet you can hit the top of the chisel so it chips away material to effectively create cuts, patterns or wood joints. - As you get more confident you can begin to carve patterns out of wood. - Chisels are good for creating carved patterns, housing joints and to chop mortises (recess or cut out in wood). ## Test yourself on Timber: Shape & Form 2 - What is the best way to speed up the sanding process?
