With a pencil and a protractor, divide the larger disc into 30-degree wedges to create 12 center lines for the bottle indents. Center and trace the smaller disc on top of the larger disc. Next, with a drill press, drill 3/8-in.-deep holes on the 12 center lines with the 1-7/8-in. Forstner bit, spacing them between the disc’s outer edge and the traced circle. Next, divide the smaller disc into 60-degree wedges and drill six more 3/8-in.-deep holes with the Forstner bit.
Cedars are strong, aromatic softwoods that are capable of enduring outdoor elements, the most common of which is the Western Red Cedar. Western Red Cedar can sustain wet environments without succumbing to rot, and as a result is commonly used for outdoor projects such as patios, outdoor furniture, and building exteriors. This wood can be easily found at most home centers for a moderate price.
