Measure and mark 3.5" four times on all sides of the wood to create cubes. Use the 18V ONE+ 7 - 1/4" Sliding Compound Miter Saw to cut along the marked lines.
Sand the cut edges of the wood in preparation for painting to avoid splinters. Use the 18V ONE+ HP BRUSHLESS Cordless Rotary tool with the Sanding Drum and Sanding Band to do so. Paint all of the blocks and allow them to dry.
Trace out the stencils on each block. Remove the material inside each circle, first by outlining each with the Cone- Shaped Engraving Burr. Next, remove the rest of the material with the Cylindrical Engraving Burr.
