The project
Archicercle manufactured these keyrings for Eight & Bob with a purpose beyond holding keys: to incorporate a magnet that operates an opening and closing mechanism. Each piece combines an engraved logo with a recess for the magnet on the reverse.
Manufacturing began by cutting the outline and hole with a CO₂ laser. The keyrings have an elongated shape, rounded corners and a hole at one end.
A fibre laser was then used for two different operations on the walnut. The logo was engraved at lower power and speed settings; the circular recess on the reverse was made at higher power over several passes to remove material. A magnet was inserted into this recess to operate the mechanism.
The pieces were finished with very fine-grit sanding and an application of linseed oil, which darkens and protects the wood. Archicercle’s contribution covered cutting, engraving, recessing, inserting the magnets and finishing the keyrings.
