If you wish to attempt cutting spherical objects with a hot wire foam cutter, you can follow these general steps:

  1. Prepare the materials: Gather the necessary materials, including a hot wire cutter, a power supply for the cutter, a Styrofoam block, and safety equipment like gloves and safety goggles.

  1. Set up your workspace: Choose a well-ventilated area with sufficient space for the hot wire cutter and the Styrofoam block. Ensure there are no flammable materials nearby.
  2. Mark the sphere’s center: Use a pencil or ruler to mark the center point on the Styrofoam block.
  3. Create a guide template: To assist with achieving a spherical shape, create a guide template out of a sturdy material like cardboard or wood. Cut out a half-circle shape with the desired radius of your sphere.
  4. Secure the guide template: Position the guide template against the Styrofoam block, aligning the curved edge with the marked center point. Secure it in place using clamps or other means.
  5. Heat the wire: Turn on the hot wire cutter and allow the wire to heat up. Refer to the manufacturer’s instructions for the specific heating time required.

  1. Cut along the guide template: Carefully move the Styrofoam block against the hot wire cutter, following the curved edge of the guide template. Slowly rotate the block while applying gentle pressure to the wire. The hot wire will melt through the Styrofoam, creating the cut. Repeat this process, adjusting the position of the block and the angle of the wire, to gradually carve out the spherical shape.
  2. Refine the shape: Once the basic spherical shape is formed, you can use sandpaper or a rasp to smooth and refine the edges, ensuring a more accurate and finished appearance.
