Yeah, about a woodshop class. Not about the business of building and selling basses.
It also applies to building guitars and basses.
I've repaired and assembled guitars and basses from parts for a few decades. I would never consider that assembly to be luthiery, it's assembly of pre-made parts.
The luthiery aspect in those cases comes after the instruments are assembled during the final stages, fret leveling and dressing, nut work, and other aspects of setup. Aspects of the customizing of those pre-made parts and repair of instruments could also fall under luthiery.
The instruments by Krappy, Wishnevsky, and others have more luthery in them than merely screwing parts together.
