• Leaves
• Expensive

Structure of wood:

• Wood is fibrous with fiber running along the length.
• Full of moisture.

Harvesting:

• Cutting down the tree.

Conversion:

• cutting the trunk
• Slab sawn, use of the whole tree, more likely to bend and warp
• Quarter sawn, lots of excess wodd not being used. less likely to deform over time.

Seasoning:

• Reducing moisture content, 70% of a tree is made up of water
• Natural
• Kiln seasoning

Board Preparation:

• Sawing to size.
• Planed all round, PAR
• Quarter Sawn.

Properties!

• Physical strength: Timber is a much stronger along the grain than across it.
• Aesthetic properties: Colour, Complex or simple grain structure.
• Moisture content: Shrinkage, Timber movement
• Protection: Dry and wet rot; insect attack.
• Operating conditions: Where will the time be used?
• Cost: Hardwood = expensive softwood = cheaper.
• Sustainability: using timber for sustainable sources.
• Sizes of board: wood can come in a variety of different sizes.

I wish i had never bought!

Being young and venerable to the 21^st century, all the latest technology grasps your eye at every glance, especially the phone industry. Last year around the month of July, I purchased a new LG Viewty mobile phone that I researched for months to find all the pros and cons, but could only find pros. I was attracted by the modern curves, the magnificent 5 megapixel camera and of course the fact that it was a touch screen phone. Being as I am a big fan of technology I was very happy to flaunt my phone about and show my friends my new purchase. After a few weeks the near flawless phone in my mind began to let its sides down and shown its true colours. The fast mobile interface was slacking and even pressing a letter to send a text would appear after 2 seconds of you typing the word, Dust collected under the screen that was highly visible as the screen is the main feature of a phone. Curves in my mind where very nice on my phone but after being in my pocket along with keys and money they soon became jagged edges. Phones are a very difficult piece of technology to keep up-to-date with ,and once you have one you love it for a short amount of time until you find all the flaws. I guess maybe I should read into things a lot more before I make a hefty investment in a new phone. The LG Viewty that was a beauty to look at, soon became a drab boring piece of equipment that is an embarrassment to the pockets of my jeans!
