bodgers

Bodgers are people who do shoddy or makeshift work—the kind that technically functions but won't hold up to scrutiny: The bodgers who installed this wiring should be banned from the trade.

In British English, to bodge is to patch together clumsily, making bodger mildly pejorative.

Historically, bodgers were itinerant woodworkers who turned chair legs on pole lathes in the beech forests of England—skilled craftsmen, though the word has lost that association.
