  1. CONSTRUCTION TECHNIQUES. PLASTICS WOODS METALS SOLDERING WELDING RIVETTING NUTS & BOLTS CASTING EXTRUSION FRAME JOINTS BOX JOINTS EDGE JOINING SCREW FASTENINGS STUD FIXINGS. FOLDING ASSEMBLY TENSOL CEMENT INJECTION MOULDING VACUUM FORMING STRIP / LINE HEATING

  2. MORTISE AND TENON – REQUIRES A TENON SAW AND ACCURATE MARKING OUT DOWELLED JOINT – BUTT JOINTS REINFORCED WITH DOWELS FOR STRENGTH WOODS TENON FRAME JOINTS BOX JOINTS EDGE JOINING NAILS & SCREWS KNOCK DOWN DOWEL MORTISE NAILS & SCREWS – USED TO HOLD ITEMS TOGETHER WHILST GLUE SETS TEMPORARY FIXING HOUSING JOINT – USED FOR SHELVES AND PARTITIONS. POSITIVE SUPPORT HOUSING POSITIVE SUPPORT

  3. SOLDERING – INCLUDES :- SOFT SOLDERING SILVER SOLDERING BRAZING SOFT SOLDERING – QUICK AND EASY METHOD OF JOINING COPPER, BRASS AND TIN PLATE SILVER SOLDERING – JOINTS ARE BUILT UP IN DECREASING TEMPERATURES BRAZING – ALLOY OF COPPER AND ZINC. VERY HIGH TEMPERATURE ALL REQUIRE FLUX TO HELP KEEP JOINT CLEAN AND STRONG. METALS RIVETTING – NUTS & BOLTS :- ROUND HEAD – REQUIRES AN ENGINEERS (BALL PEEN HAMMER) AND RIVET SET (DOLLY) TO ROUND OVER THE HEAD OF THE RIVET POP RIVET – QUICK AND EASY METHOD OF JOINING THIN PLATE. WEAKER THAN A SOLID ROUND HEAD RIVET. NUTS & BOLTS – A TEMPORARY FIXING THAT RELIES ON FRICTION TO HOLD PARTS TOGETHER. HOLDING THROUGH MECHANICAL ADVANTAGE OF SCREW THREADS. SOLDERING WELDING RIVETTING NUTS & BOLTS WELDING INCLUDES FOLLOWING OXYGEN – ACETYLENE – VERY HOT FLAME USING BURNING GASES TO MELT BOTH PARENT METAL AND FILLER ROD – MAINLY THIN PLATE WORK. ELECTRIC ARC – USES ELECTRICAL CURRENT (ARC) TO CREATE HEAT ENOUGH TO FUSE TOGETHER PARENT METALS – CAN BE USED FOR LIGHT AND HEAVY PLATE WORK.

  4. PLASTICS TENSOL CMENT 70 TENSOL CEMENT 12 A SOLVENT BASED ADHESIVE. NOT VERY STRONG. WORKS BY ATTACKING THE SURFACE OF THE ACRYLIC TO BOND THEM TOGETHER. SUPPLIED READY TO USE AND SETS QUICKLY A POLYMERISING ADHESIVE LIKE ‘LIQUID’ ACRYLIC THAT LINKS WITH THE MATERIAL RESULTING IN A JOINT THAT IS NEARLY AS STRONG AS THE ACRYLIC ITSELF. NEEDS CAREFUL MIXING AND A LONGER SETTING TIME. TENSOL CEMENT DRILLED AND JOINED WITH MACHINE SCREWS MAKE SURE YOU SUPPORT THE UNDERNEATH OF THE PLASTIC BEFORE DRILLING DO NOT OVER TIGHTEN TO AVOID CRACKING THE MATERIAL.

  5. PROCESSES WOODS METALS PENCIL, RULER, TRY SQUARE, MARKING GAUGE, MARKING KNIFE. SCRIBER, ENGINEERS SQUARE, STEEL RULER, CALIPERS, DOT PUNCH, DIVIDERS. HACKSAW, TIN SNIPS, COLD CHISELS, ABRAFILE TENON SAW, COPING SAW, FRET SAW, BENCH HOOK, MITRE BLOCK COMMON TO ALL MARKING OUT CUTTING TO SIZE SHAPING/FORMING JOINING FINISHING FORGING, PRESSING, BENDING, TURNING, MILLING, DRILLING SANDING MACHINE, JACK PLANE, CHISEL, MALLET, SPOKESHAVE, TURNING, DRILLING. GLASS PAPER, VARNISH, PAINTS, POLISH, WAX. EMERY CLOTH, WIRE WOOL, PAINT, POLISH, DIP COATING.

  6. PLASTICS MUST HAVE PAPER BACKING LEFT ON. - PENCIL, CHINAGRAPH OR SPIRIT PEN, SCRIBER, RULER, TRY OR SET SQUARE, MOST METAL WORK MARKING OUT TOOLS. STRIP BENDER/HEATER, VACUUM FORMER, INJECTION MOULDING, CASTING. DRAW FILING, EMERY CLOTH, WET AND DRY, POLISH, HACKSAW, COPING SAW, BAND SAW, HAND FILES, COMMON TO ALL MATERIALS JIGS AND FORMERS USED TO MAINTAIN ACCURACY FOR MARKING OUT, CUTTING AND SHAPING. ESSENTIAL TO REPEAT ACCURACY OF PARTS THAT GO TOGETHER TO MAKE COMPLETE UNIT. MARKING OUT CUTTING TO SIZE SHAPING/FORMING JOINING FINISHING

  7. SCALE OF PRODUCTION ITEMS THAT ARE PRODUCED (MADE) SINGLY. POSSIBLY DUE TO THE NATURE OF THE PRODUCT, E.G. BRIDGES, SATELLITES, JEWELLERY, WEDDING DRESSES, MACMILLAN COLLEGE AND OF COURSE YOU - SAFETY AND RELIABILITY ARE OFTEN OF HIGH PRIORITY THAN COSTS, ALSO HIGH AESTHETIC CONSIDERATIONS. ONE OFF PRODUCTION A SYSTEM OF PRODUCING IDENTICAL ITEMS IN FIXED NUMBERS FOR A SPECIFIC CLIENT. E.G. SCHOOL TIES, FURNITURE, DESIGNER CLOTHING, ITEMS WITH CLIENT LOGO RATHER THAN MAKERS LOGO. WHEN THE BATCH IS COMPLETE, THE TOOLS USED CAN BE USED TO PRODUCE A BATCH OF DIFFERENT PRODUCTS. BATCH PRODUCTION MASS PRODUCTION PRODUCING ITEMS IN VERY HIGH QUANTITIES THAY CAN RECOVER THE COSTS OF TOOLING UP. COST OF MANUFACTURE IS AS LOW AS POSSIBLE. E.G. CARS, BIRO’S, CHOCOLATE BARS, SCHOOL SHIRTS, CD’S. NO FIXED NUMBER AND NO SPECIFIC CLIENT.

  8. DISABLED ACCESS REQUIRED HEALTH AND SAFETY THE EXAM WILL BE LOOKING FOR MORE THAN JUST THE BASIC UNDERSTANDING OF – WEAR GOGGLES, TIE YOUR HAIR BACK, WEAR AN APRON. IT WILL BE CONCERNED WITH RESPONSIBILITY FOR HEALTH AND SAFETY I.E. AWARNESS OF SAFETY SIGNS AND THEIR MEANINGS LEGISLATION REGARDING ROOM LAYOUT POSITIONING OF SAFETY EQUIPMENT SAFETY GUARDS AND USAGE SPEEDS OF MACHINERY TRAINING PROGRAMMES ADEQUATE SPACE FOR WALKWAYS BETWEEN TABLES WHERE THE EMERGENCY STOP BUTTONS AND FIRE EXTINGUISHERS ARE LOCATED. THAT THEY ARE IN TACT AND MOVE FREELY. SIGNS IN PLACE INFORMING THEIR USAGE THAT REVOLVING CUTTERS CAN BE ADJUSTED MANUALLY ACCORDING TO THE SIZE OF MATERIAL OR HOLE TO BE CUT MAKING USE OF TRAINING TO ENABLE SAFE USE OF MACHINERY AND EQUIPMENT – GET SUPERVISION.

  9. MARKETING USING COMPUTERS IN DESIGNING INTERNET RESEARCH - VISITING THE CLIENT . GRAPHICAL RESULTS OF YOUR QUESTIONNAIRE – INFORMATION FOR YOUR SPECIFICATION LIST. LETTERS TO CLIENTS – FINDING OUT THEIR NEEDS . FEEDBACK TO LET YOU KNOW THAT YOUR IDEAS ARE ACCEPTABLE BY THE CLIENT/CUSTOMER VALUABLE INFORMATION BEFORE YOU GO TO MANUFACTURING STAGE. QUESTIONNAIRES TO CUSTOMERS. FINDING OUT WHAT THEY WANT – COSTS, MATERIALS, SIZES, APPEARANCE, COLOUR ETC. WORKING DRAWINGS. INFORMATION TO HELP MAKE YOUR IDEAS. IS THE STORAGE SYSTEM SUITABLE FOR A PROMOTIONAL GIVE AWAY?

  10. ERGONOMICS AND ANTHROPOMETRICS • THE SCIENCE CONCERNED WITH MEASURING PEOPLE AND HOW THEY WILL FIT THE PRODUCT. • STATIC DIMENSIONS – TAKEN WHEN A PERSONS BODY IS IN A FIXED POSITION. STANDING, HOLDING TOOLS ETC. • DYNAMIC DIMENSIONS – TAKEN DURING MOVEMENT. CONCERNED WITH THE AREA OF REACH FOR ARMS AND LEGS. • THE PRODUCT IN RELATION TO ITS ENVIRONMENT (E & E) AND ITS USER. • HUMAN PHYSIQUE – HEIGHT, WEIGHT, RANGE OF REACH AND MOVEMENT. • HUMAN ABILITIES – STRENGTH, POSTURE, RANGE OF MOTION. • HOW THE PRODUCT FITS IN WITH ITS SURROUNDINGS – LOOKS, SIZE, FEEL, COMFORT ETC. ERGONOMICS USES ANTHROPOMENTRICS YOU CANNOT DESIGN A PRODUCT WITHOUT FIRST MEASURING THE USER THIS WILL BE IMPORTANT WHEN THINKING ABOUT THE HAND ACCESS TO ALLOW RETRIEVAL OF THE CD BOXES

  11. AESTHETICS IT IS NOT JUST HOW THE PRODUCT LOOKS. HOW IT LOOKS IN RELATION TO OTHER ITEMS IN THE ROOM – E.G. LAMP, PHONE, DIARY, EXEC’ TOYS COMPUTER, STERIO, IPOD ETC. AESTHETICS WHAT DOES IT FEEL LIKE – TEXTURE, COMFORT, FITTING, MATERIALS ETC. ARE THE SIZES CORRECT AND IN RELATION TO ONE ANOTHER – HEIGHT, WIDTH, THICKNESS. DO THE CD’s, DVD’s FIT WELL APPEARANCE – COLOURS, SHADES, STYLE, CULTURE, THEME, VALUE FOR MONEY. AN OPINION OF THE WHOLE PRODUCT I.E. IS IT SUITABLE FOR THE PURPOSE???
