  1. 1DESIGNWOODS
  2. 2TimberWood used in manufacturing of an attract
  3. 3HardwoodsNothing to do with how hard the wood is but hardwoods come from deciduous trees, trees that shed leaves in autumn
  4. 4SoftwoodsFrom coniferous trees, these have cones and needles that fall off them

    - Have specific purposes and specific properties
    - Often use any wasted timber
    - Uniform with few imperfections
    - Do not split
    - Can be in finished formats
  24. 24SteambendingVeneer are put in a steam chamber. Steam is introduced ate one end at it travels through heating it and as the steam cools it condenses back to water and drains away. After some time u take it out and it is malleable and have a change of properties
  25. 25LaminatingInvolves no heat but uses multiple thin layers of veneer and bonding them to each other over a former
  26. 26Marking out/shaping/glueing together.
  27. 27Vacuum forming processthe mould is placed on the platen, then the thermoplastic sheet is placed over the airtight seal, clamped above the blaten, the heater is pulled across then the platen is raised so the ould is sitting underneath the plastic, the vacuum is turned on and the plastic is sucked over the mould
  28. 28Marking out/Shaping/Gluinguses

  32. 32Try-squarelines at a 90-degree angle to the edge
  33. 33Centre punchto create a divot for the drill or machine to hold on to when drilling into it.
  34. 34Dividersused to create circles and spherical line on the material
  35. 35Mitre squareto create a 45-degree angle on the material
  36. 36Scriberto make scratches on the material instead of a pencil (which can be rubbed off)
  37. 37Shapinguses
  38. 38Chisel and malletto shave off large pieces of material which would take to long for a sander to do
  39. 39Sandpaperto smooth out the materials at the corners or on the material, used to get away pencil lines.
  40. 40needle filesused to file away small amounts of material in hard to get to areas
  41. 41Filesuses to smoothen corners and to smoothen the material
  42. 42non-ferrous metals.
  43. 43AluminiumLight in weight and malleable but strong, a good conductor of heat and corrosion-resistant. Uses - Drink cans, saucepans, bike frames

  46. 46Drill bitsUses
  47. 47Twist bita viable option for drilling through most woods and plastics, as well as some thin metals
  48. 48steep drill bitdrill bits allow a user to gradually increase the size of an existing hole without needing to attach a new drill bit.
  49. 49Forstner bitbits that are suitable for making relatively large flat-bottom holes and allow for these holes to have a very clean finish,
  50. 50masonry bitideal for drilling through brick, concrete, and stone
  51. 51brad-point bitThe W-shaped point that enables them to create very precise holes in wood.
  52. 52auger bitbest suited for drilling large holes in hard, dry lumber hexagonal or a triangle shank to provide a more secure, stable connection with the chuck.
  53. 53spade bitspade bits utilize a W-shaped tip similar to that of brad-point bit, but on a larger scale
  54. 54countersink bita specialized type of drill bit optimized for making bevelled openings at the top of a pilot hole
  55. 55spear point bitflat, arrow-shaped tips are able to safely boreholes in a piece of glass without damaging the pane’s structural integrity.
  56. 56rivet bitthose shanks often feature a tip at both ends, allowing a user to double the number of holes they drill before replacing a bit.
