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

Motorcycle Project The Main body or frame: Body profile made from sheet Aluminium 1 mm, 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.

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

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

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

Motorcycle Project Finishing Methods As with all projects there 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

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

Motorcycle 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.
