How to Carve Stone Bird Baths
- 1). Place the large stone on a work surface with the face that you want for the bowl of the bird bath facing upright.
- 2). Draw a circle with a compass on the top surface of the stone. This will define the edge of the bowl for the bird bath.
- 3). Use an angle grinder with a stone grinding attachment to grind a grid pattern inside the circle you have drawn. Space the lines in the grid approximately ½ inch apart. Grind around the perimeter of the circle. The depth of the ground lines should be approximately ½ inch.
- 4). Use a tooth chisel and a mallet to break out each of the squares in the grid. Repeat the grinding process and chiseling out process until you have reached a depth that you are satisfied with for the bird bath bowl.
- 5). Use a flat chisel and mallet to refine the curves of inside of the bowl. Create a smooth surface inside the bird bath. Smooth out the outside edge of the bird bath bowl with the flat chisel. Chip off small pieces at a time until the perimeter is completely smooth.
