  1. Design and make a project of simple construction,suitable for a Leaving Certificate Technology class. Three part design: • Main body • Front forks • Handlebars Additional components required: • 3 Wheels • 1 Motor • 2 Battery Holders • 1 Switch • 1 Gears Wheel • 1 Worm gear • 1 Seat & Petrol Tank • 4 AA Batteries

  2. The Main body or frame: Body profile made from sheet Aluminium 1mm, Blank size shown in the diagram. Finished outline is Symmetrical. Profile marked out, holes drilled and then cut from given blank according to accompanying dimensioned drawing Finished part. The finished profile is then bent to shape as shown.

  3. Front forks: Mark out the desired profile according to the given dimensions. Then drill the three Ø 4mm holes and cut out the profile. Now bend both sides at right angles to produce the final design as shown.

  4. Handlebars Mark out and drill the blank. Cut out the profile and finally bend as required. Completed Handlebars shown opposite.

  5. Handlebars Front forks Main body Main parts assembled: Assembled view of the three main parts of the Motorcycle Finished Motorcycle: The additional components are then added to give the final assembled Motorcycle project shown.

  6. Finishing Methods As with all projects there are a number of possible finishes. Polishing: Fine grade emery cloth Graded Steel Wool Mechanical: Polishing Mops & soaps Mottling Chemical Polishes: Brasso, Silvo, Peek. Plastic Coating: Dip coating Painting: Standard colours & specialist paints Metal Spraying: Cold spray able Metal coatings. www.artcam.com

  7. Black Rusty Brown Tri Colour Flemish Violet Metal Dyes: These are special chemical that react with the metal to produce a range of finishes. Antiquing solutions Cupric Nitrate Cobalt Nitrate Copper Sulphate Silver Nitrate Sample of special Chemical finishes: www.ssschemical.com/

  8. Project Enhancements: Introduce Timing circuits: Travel set distance forward / reverse Flashing LED’s: Astable circuit Sound Chip: Motor Cycle Sound when switched on. Tilt Switches: Turn off the Drive should the Motor Cycle fall over. Finally design and make a suitable Seat and Fuel Tank for the project.

  9. Sheetmetal Clamp Tin Snips Hand Nibbler Conical drill Folding Bars Bench vice folders Simple vice jaw folders Combined bench mounted, hand operated rollers, folders and shears. Rollers Folders Shears Some typical Technology room sheet metalworking tools:
