Planed all around (PAR) - mechanically planed on all sides and finish can be easily applied. used for furniture and internal features

Question 2

what is seasoning?

Answer 2

The process of drying wood as high moisture content can cause uneven evaporation of wood and cause faults like cupping twisting bowing.

Question 3

two types of seasoning

Answer 3

air drying - planks are stacked and air is allowed to circulate - slower and less effective and efficient kiln drying - more expensive but more effective as it uses more heat and pressure

Question 4

manufactured board
- two processes n examples

Answer 4

lamination - wood layers is bonded together using an adhesive, plywood examples
compression - wood shredds to fibre and pulp is compressed together at high pressures and

Question 5

veneer and two tvpes

Answer 5

a thin layer of natural timber placed on cheaper woods
rotational- a tree trunk is turned on an industrial machine and knife cut

Question 6

Advantages of manufactured boards

Answer 6

cheaper and environmental better - low grade recycled wood is used
no defects(warping twist cupping bowing or nots) available in large sheets which saves energy joint sheets together
large variety of smooth finishes veneers and laminates

Question 7

disadvantages of manufactured board

Answer 7

• Will blunt tools
• Edges must be covered and treated
• Dust particles may be hazardous adhesive particles can be hazardous

Question 8

sustainable timber production

Answer 8

unsustainable production causes desertification and deforestation and global warming provenance(the supplier or retailer being able to prove the wood is sustainable) has to be sought after. Organisations like the forest stewardship council help this

Question 9

Answer 9

thickness start at 3mm and increase in intervals of 3,,
lengths start. available in full sheets of 2440mm by 1220mm

Question 10

veneer stock thickness

Answer 10

available in thickness ranging from 0.4 to 4.5mm but typically 1.5mm

Question 11

plank stock width and lengths

Answer 11

lengths start at 1.2m and increase in 0.3m to 4.8m
widths increase in 25mm

Question 12

dowels and mouldings

Answer 12

some wood can be bought in designs called mouldings. an example is an architrave or skirting boards

dowels are cylindrical rods used for joining pieces of woods

Question 13

Question 17

drilling factors to consider

Answer 17

type of bit used, so right shape and size is cut
depth of cut
feed rate, as too high right can put too high pressure on part but too Low can cause chip clogging
speed - too high speed can cause scorching

Question 18

two types of drills

Answer 18

pillar drill - good for accuracy and power
cordless drill - high adaptability and portability

Question 19

types of drill bit

Answer 19

wood drill bit

Question 20

wasting, abrading, sanding tool

Answer 20

wasting tools - a smoothing plane or chisel

Question 21

wood turning technique

Answer 21

a wood lathe is used to spin materials and special chisels calls scraper gouge and parting tool are used

Question 22

bending

Answer 22

wood can be bent by increasing the moisture content to get cool shaped and held in place. a steamer box is used to increase moisture in wood fast

Question 23

knockdown fitting

Answer 23

used with flat pack furniture as temporary fixing that joins pieces together with screws that are easily dismantled

Question 24

flatpack furniture advantages and disadvantages

Answer 24
