transferring layouts to metal
Materials and Equipment
- black permanent marker
- drafting tools
- water-based white paint
- soft lead pencil or carbon paper
- ball point pen or hard lead pencil
- rubber cement or spray adhesive
- Use a black permanent marker to thoroughly coat the surface of the sheet metal.
- Using a scribe, carefully scratch through the marker surface to make a thin clear line. Drafting tools such as templates, french curves and steel straight edges should be used if a clean regular shape is desired.
- Remove any oils from the sheet metal surface with soap and water or isopropyl alcohol.
- Paint on a thin coat of a water-based white paint such as Chinese white tempera and allow to dry.
- Cover the back of the pattern to be transferred with graphite using a soft leaded pencil, or carbon paper may be used instead of coating the back of the design.
- Place the design over the sheet metal face up, and trace over the design with a ball point pen or a hard leaded pencil to transfer the pattern.
- Remove the white paint by sanding.
- Apply a coating of adhesive to the back of the pattern and allow to dry thoroughly (3M Super 77 spray mount works best).
- Place the pattern into position on the sheet metal, and use a burnisher to rub it down completely.
- Saw along the pattern lines cutting through the paper.
- Peel off the paper pattern.
