Reduces oxygen in the atmosphere,
Increases the likelihood of flooding in deforested areas
Increases global warming
Increases soil erosion in deforested areas.
Use native woods over tropical woods
Use woods from suitable forests (FSC labelled)
Use manufactured boards over tropical woods
Use veneered manufactured boards
Plant trees within local communities

METHODS OF CARVING: Chip carving, Relief Carving, and Carving in the round (3D carving)
HOW TO TRANSFER A DESIGN ONTO WOOD USING CARBON PAPER:
1. Collect the wood, the design, carbon paper, sellotape and a pencil.
2. Sellotape the carbon paper onto the wood.
3. Sellotape the design over the carbon paper.
4. Trace over the design with a pencil.
5. Make sure all lines have been traced before fully removing the carbon paper and the design.
6. The design should be present.
HOW TO CARVE IN THE ROUND - MARKING OUT AND CARVING.
-> MARKING OUT
1. Draw the elevation(s) and plan(s) of the design onto paper.
2. Transfer the images onto the wood using carbon paper.
1. Cut the rough shape of the design using a coping saw or band saw.
2. Using gouges and shaping tools develop the overall final shape of the piece.
3. On the rough, draw and carve the finer details using chisels and other tools.
4. Sand and finish.
WOODS SUITABLE FOR CARVING:
-> REASONS FOR CHOICE OF WOOD
Cost, Appearance, Durability, Work ability, Finishes well, Renewable, Environmentally friendly.
THROUGH AND THROUGH SAWING
Boards are likely to cup
No particular grain pattern
Less durable as there is a lot of sapwood present
QUARTER SAWING / RADICAL SAWING
Attractive grain pattern
Boards are not likely to shrink
Boards wear evenly (good for flooring)
Expensive, High labor cost
Lots of waste is produced
Boards are not as wide as in plain sawing
Flame like grain pattern
Boards season quickly
Boards can take nails without splitting because of the grain pattern
Boards tend to shrink and cup
Timber is prone to warping and cupping
Expensive as the log has to be turned 90° for each cut
(Its a bit late, >.> sorry lol)
Manufactured boards didn't come up this year, but they probably will next year.
TYPES OF MANUFACTURED BOARDS:
Oriented Strand Board (OSB)
Medium Density Fiberboard (MDF)
HOW CHIPBOARD IS MANUFACTURED:
1. The wood is processed into particles
2. The particles are mixed with adhesive
3. The particles are spread out and pressed with heat presses.
4. The wood is seasoned
5. The boards are cuts and sanded.
ADVANTAGES MANUFACTURED BOARDS HAVE OVER REGULAR BOARDS:
Less likely to cup
Cheap in large quantities
Can be veneered to resemble hardwoods
WAYS MANUFACTURED BOARDS HELP THE ENVIRONMENT:
Can be used instead of tropical woods
Can be veneered to resemble tropical woods
Are more durable and long lasting then solid boards.
