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.
