Learning objectives

    1. Structures
    2. Machines
    3. Networks
    4. Processes
  2. How to fix your own stuff
  3. Compare motorcycles w/ auto
  4. Learn tools
  5. Dynamics
  6. Philosophy
  7. Figure out what you like
  8. Compare evolution of motorcycle
  9. Evaluating design
  10. Manual tabor
  11. Teamwork

Shop class as soulcraft (second six weeks) —> importance of manual labor

  • Focus on motorcycle references

Zen and the art of motorcycle maintenance (first part of course) —> some philosophy

Triumph Tiger Cub —> Notes from readings

  • 200 cc (cubic centimeters: cylinder capacity)
  • Two-stroke engines (more powerful than four)
  • Fork: structure that holds wheel
  • Ignition points: where fuel and air mixture are ignited by spark — timed by ignition points
    • Advanced: piston going up when spark fired
    • Retarded: piston already going down when fired (ex. Model T)
  • Flaw: top Fram tub flower than normal, so fuel tank needs to support headstock
  • Seizure: piston expands & locks into place (due to seating)
  • 4 strokes: intake, compression, power, exhaust
  • Overhead valve: valves above piston —> has knicks to make room for valve

Unfamiliar terms (& more) in reading

  • Dry sump lubrication system – no oil splashing around
    • Better seal on piston rings, separates oil from air in tank, ^ performance
  • Rockers & rockerboxes
    • Pushrods open valves (intake, compression, power, exhaust)
  • Cast iron barrel w/ no sleeve
    • Advantage: works better, disadvantage: heavy
    • Air-fooled: if gets too hot, m can auto-ignite (fire w/o spark plug)
  • Rectifier (goes together w/ coil): electric device w/ one-way valve
    • Convert AC (alternating current) to DC (direct current)
  • Front brakes more effective than back brakes
    • Bc forces push downward into ground from front wheel
  • Two types of brakes: drum (can lock up) & disk (can get wet & will then work less effectively)

*will do online training and assign people to groups in lab
