Finishing wood to a good quality.
Objectives:
Understanding different types of wood.
Manufacturing a usable product from a softwood.
Understanding shape and form.
Choosing and using the correct manufacturing tools
Brief:
.Design and make a quality assured wooden spatula using the dimentions given.The spatula must be able to stir and flip food using an ergonomically designed handle

Research:
In order to understand the materials we are going to use you need to do research:
You will learn about -The sustainability and use of wood as a resourse.
You will learn what the different types/ clasifications of wood is.
You will understand grain in wood and how to finish off wood to a good quality.
What do we use wood for in everyday life? Name some!
Wow is the tree changed into a usable state? (Watch the video and discuss)

Woods can be divided into two main
categories – softwood and hardwood.
This is not a description of the wood – it just means what type of tree it comes from.
Softwood:
nMost softwood trees are coniferous (cone bearing). They typically have thin, needle- like leaves and are evergreen (pine, cedar, yew). They grow in colder climates and are fast growing- most reaching maturity within 30 years. This makes them easy to replace with new trees, so they’re usually cheaper than hardwoods.
Hardwoods
nMost hardwood trees are broadleaved and deciduous (they shed their leaves annually). For example: Oak, Mahogany, Beech, ElmnBroadleaf trees grow in warm climates and are usually slow growing. They can take around a hundred years to mature, so there are more expensive than softwoods.nColours are: Oak- rich light brownnMahogany- reddish brownnBeech- creamy/ pinkishnElm- light reddish brown
Solid woods are cut straight from the tree. Man- made woods (boards) are made from the bits of waste that are produced when the trunks and branches are cut into planks.
Plywood:
Important properties: very strong, doesn’t warp, Exterior plywood is water resistant.
nMaking tips: can split when cut, outside of the board can be finished with a nice veneer (thin layer of good quality wood).
nTypical uses: containers, flat cut- out figures, mechanical parts, wheels
nIn general: it’s made up of several layers (always an odd number of them) and the layers are glued with their grain at 90 degrees to each other. That’s the reason why it is very strong.
(Watch the Video Clip below.)
Hardboard
Important properties: brittle, goes soggy with water nMaking things: tears easily, difficult to finish edges nTypical uses: covering panels
MDF (Medium density fibre board)
nImportant properties: hard, keeps edges well, goes soggy with water, has smooth faces and takes paint and other finishes well nMaking tips: blunts tools, shapes easily, finishes well, drills well nTypical uses: block models, vacuum forming moulds, small bases
Chipboard nImportant properties: brittle, edges easily damaged nMaking tips: difficult to shape, blunts tools, finishes poorly, catches on drills nTypical uses: large bases; because it’s cheap but not very strong, so is usually used with a hardwood or plastic veneered surface in cheap furniture
Protection: nPolyurethane varnish can be used to seal and protect the surface of the wood, and give it a smooth surface finish. You can buy it clear or in a wide range of colours. nWoodstain can be applied to wood to enhance the appearance of the wood’s grain. It’s available in natural but also in bright colours. Stains usually don’t protect the wood, so varnish may need to be appli nOil can be used to maintain a natural appearance of the wood. Some oil- based finishes also offer protection to wood used outdoors. nPaint is often used to colour and protect wood. Emulsion paints are cheap, but they are water- based, so they don’t protect wood from water. nPolyurethane paint is more expensive but is waterproof and much tougher.
