A&E NOVEMBER 2019 • 27 Step-by-Step Tutorial Materials Used: • SR3000 3-mil • Cover paper • Aluminum oxide 150 grit • Hunter's knife • Stone Tone black paint • Painter's tape • 2 0 3 4 V X A Sa n d c a r v i n g s y s t e m (note: the blasting settings listed in step five may change if using a different machine) Step One: Create a sandcarving stencil/ mask using SR3000 3-mil Self-Stick film (or equivalent product; if using something different, consult proper settings and appli- cations for that film as they may differ). Note: Cover paper (backing paper) can be applied to Self-Stick film to store sandcarving stencil until ready to use. Step Two: Clean the blade and apply the stencil to surface. Align the design to desired position. Note: Use extreme caution when handling sharp blades. Step Three: Use a squeegee and bur- nish with pressure the stencil to the surface. Remove the clear plastic liner. If the stencil lifts up, remove while peeling away the liner then squeegee again. Step Four: Protect the handle and blade with plastic wrap and secure with painter's tape. Note: Plastic wrap is not sand resistant; it is only used to protect the item from abrasive. Step Five: Sandcarve the design — blast at 30 psi using aluminum oxide 150 grit. Sandcarving time is approximately 30-40 seconds. Blast until the polish is removed; no depth will be achieved with sandcarving metal; only remove the polished surface. Step Six: Paint-fill the sandcarved area. Leave the Self-Stick stencil on the surface after sandcarving. This stencil now becomes the painting stencil. Stone Tone black paint was used for this project because we feel it is durable and dries quick, but feel free to use the paint of your choice. Any desired color can be used when painting metal surfaces. Choice of color is a benefit with sandcarving. Carefully use an air gun to remove any dust from the surface. To apply the paint to the surface, shake the can well and apply it in light coats. Inspect the etched area to ensure the entire surface it painted. Step Seven: Once the paint is dry, remove the photomask and plastic wrap. Use small strips of tape to remove any photoresist, then clean the surface with glass cleaner.
