Situate a light source near your work surface, directing the light to shine over the saw. If you can, work outside in the sunlight for the most effective lighting.
Set the petrified wood into a vise assembly to hold it steady during the cutting process. Clamp the wood tightly by screwing in the wing nuts.
Slide the vise assembly up to the trim saw. Put on the appropriate safety gear of goggles and ear protection. Fill up the oil reservoir. The oil drips over the blade as you cut through the quartz in the petrified wood, keeping the blade cool and reducing the rock dust. Turn on the saw.
Slowly slide the petrified wood against the blade, allowing it to scratch through the hard surface, forming straight and even layers. Rock cutting takes time and a steady hand so be patient as you cut the rock, allowing the blade to slowly cut through the petrified wood.
