Reading
Chapter 4 recap of Shop Class as Soulcraft.
· Themes:
o Different people are inherently better at different jobs.
o Jobs also influence the worker.
o Failure teaches humility.
· Content:
o Discusses the beginning of the author’s shop experience. Got an apprenticeship at a Porsche dealership as a teenager. Didn’t learn much about car repair due to a subpar mentor.
o Father was a physicist and tried to impart wisdom using abstract advice that wasn’t easily received by the author.
o Talks about trying to figure out someone else’s design (i.e. his VW Beetle, God’s design of the human body, etc.) is a humbling process.
· Motorcycle/Technical terms:
o Turbocharger: a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber.
o “Matchporting”: matching up the exits of the intake manifold runners to the entrances of the head’s intake ports.
o Swing Axle: is a simple type of independent (rear wheel) suspension allowing wheels to react to irregularities of road surfaces independently, and enable the vehicle to maintain a strong road holding.
o Transaxle: an automotive mechanical component that combines the functionality of the transmission, axle, and differential into one integrated assembly.
Nitriding: a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface.
