Making a spider-lamp out of 8 cheap Ikea anglepoise knockoffs

Budapest designer Petra Nikoletti bought eight Ikea Forsa lamps and a salad bowl and had a locksmith precision fit them into a "spider lamp": "I bought 8 Ikea FORSÅ table lamp, and only used the arms and the heads. A custom-made cylinder is holding them and a Blanda Blank Serving Bowl (20 cm, painted black) is hiding the wires. A black hollow shaft is connecting the lamp to the ceiling, the cover at the end is also a Blanda Blank, but the smallest one."

I'm a bit confused about the locksmith part — is that a translation error, or are locksmiths really an untapped source of high-quality machining and enamelling?
