Agenda:
- Reflections and learnings from the previous shop class
- Discussion of Zen and the Art of Motorcycle Design (Chapter 3)
- Discussion of Shop Class as Soulcraft (Pages 11-31)
- Continue disassembly in shop in sub-teams
Reflections and learnings from the previous shop class
- Top and Bottom End Groups- Troubleshooting while taking out sprockets and other specific fasteners in the engine, learning about and avoiding mushrooming.
- Clutch- Disassembly and cataloging parts using the manual
- Electrical- Looked at a PDF to understand how the electric systems work
- Fasteners/ Carburetor- Researched how a carburetor works, along with some disassembly
- Fork- Found all the parts and catalogued them, referring to the manual
- Frame- Took the pin out of the swing arm using an arbor press and copper mallet
- Wheel- Disassembled front wheel, took out spokes.
Zen and the Art of Motorcycle Design (Chapter 3)
Motorcycle References:
- Speedometer- Has a magnet which deflect the needle proportional to the speed. Magnetic Breaking uses eddy currents to break
- Tachometer- measures angular speed (rev/min= rpm)
Content:
- Interesting to equate the concept ghosts and scientific laws with the argument that both are human invention and “exist in the mind”
- Concept that everything that we “know” it true, is actually just invented by us
- Idea that lots of philosophy is as much about posing questions and leaving it for the reader to interpret it as it is to answer questions
- The philosophical side of the story really comes to light in this chapter
Shop Class as Soulcraft (Pages 11-31)
Motorcycle References:
- Soldering/ Braising/ Welding (in order of effectiveness)
- Carbs and Breaks- could identify what was being cleaned by the smell, as each is cleaned with a different solvent
- Backfire (explosion outside ignition chamber- flashes coming out of carb) and afterfire (unburnt fuel in the exhaust causes an explosion) have different sounds
- Starter Clutch- clutch associated with electric start
Content:
- Theory vs Practice, why is there is a superficial divide between “thinkers” and “doers”? Divide between intellectuals and tradesmen.
- Diagnostic technique- not just hands-on but also intellectual- should equate surgeons to mechanics
- Education- decline in vocational education, but now is rising again; standardized tests, knowing factoids is great but you can’t do anything; idea about learning without practice
- “Tell them, Show them, Let them do it”- different people learn differently.
Shop Time
- Further disassembly and cleaning of parts
- Getting an accurate inventory of spare parts and documenting what we need to order
