Making beautiful things from epoxy and wood happens to be [Peter Brown’s] area of expertise. He was recently quested with reverse engineering the ring design of the Canadian manufacturer secret wood — a unique combination of splintered wood and epoxy — and achieved impressive results.
As it turns out, splintering wood on purpose and in just the right way is harder than not taping the kerf. [Peter] tried breaking wooden boards in half over his knee, in a vise, he kerfed the wood to make it crack more straight, he tried thin boards and thick boards. Eventually, he got the results he wanted by breaking a thicker slate of beechwood in an improvised bending press.
He then filled the crack with epoxy resin, to which he added just a few drops of blue dye and – intentionally – a few air bubbles. The embedded fog effect is achieved by consecutively pouring two different shades into the mold. With the secret sauce sorted out, [Peter] could start working on the ring shape of the mysterious material. He drilled a center bore, cut out the rough shape on the bandsaw and finalized the cut on the belt grinder.
After manually sanding the epoxy gems through all the grids and giving them a spin on the buffing wheel, they turned out just as beautiful as the original ones. Enjoy the video below, where [Peter] goes through all the details of how these rings are made:
