I recently finished this large tabletop backgammon board using my (SP5 2x4). The build features two 1/4" maple playing surface encased in a solid 3/4" walnut frame.
Design
• I carved the triangles using a V-carve toolpath. While I initially considered traditional wood inlays, I opted for cast epoxy to achieve a sleeker, more modern aesthetic.
• The playing pieces are made from Oak with a carvered center for epoxy pouring.
• I carved the walnut part with a Bullnose bit to 1/2" for holding the pieces during the play.
• The Marble Effect: I hand-mixed the pigments during the pour to create a custom marble swirl.
• Once the Epoxy was cured, I put it back on the CNC and use a McFly bit for surfacing the maple boards. That made the Epoxy perfectly flat and equal to the surface.Of course, sanding is the next logical step.
• Pro-Tip (CC pro): If you’re using epoxy, the Toolpath Volume feature in the simulation screen is a lifesaver. I layered my toolpaths by color (Green vs. White), which allowed me to calculate the exact volume of resin needed for each pour.
Personnal Touches
Since this was a gift, I created a matching custom storage box for the playing pieces.
• Material: Maple lid with walnut sides (Miter joined with splines).
• Detailing: I personalized the top with a name engraving and utilized the Texture Function in CC pro to add a premium tactile feel to the surface.
