Fabricating a reflector for inspection of the BSW
- Obtain an aluminum plate and the tools below:
What to obtain
- Aluminum plate: 300 mm (11.8 in) (W), 150 mm (5.9 in) (H) and 0.5 mm (0.02 in) (D) or moreNOTE: To fabricate the plate easily, we recommend that the plate should be 0.5 mm (0.02 in) thick. If thinner, the plate may be curved easily. If thicker, it will take longer to fabricate the plate.
- Protective gloves
- 300-mm (11.8 in) long scale
- Knife
- Adhesive tape
- Aluminum plate: 300 mm (11.8 in) (W), 150 mm (5.9 in) (H) and 0.5 mm (0.02 in) (D) or more
- Wear protective gloves and scribe the lines on the aluminum plate as shown below.NOTE:
- Check the scribed lines for accuracy (parallelism and perpendicularity) in several points.
- Place cloths under the plate to protect it from scratches.
- When the plate is covered with a protective film at the factory, do not peel off it.
- Cut the plate according to the steps below:
- Align a scale along the scribed line.
- Hold the scale securely. Use it as a guide to make a V-groove on the plate with a knife.
- Repeat the process above approximately 20 times to deepen the V-groove.
- Bend the plate slightly to check that the plate can be bent sharply along the V-groove as shown below. If no, the V-groove is too shallow. Repeat step 3.
- Bend the plate several times to cut it.
- Assemble the plate pieces according to the steps below to make a triangular pyramid.
- Use three of four plate pieces. If the piece is covered with a protective film, do not peel off it yet.
- Place the plate pieces and apply adhesive strips together as shown below. When the plate pieces are covered with a protective film, apply the strips on the non-covered surface. (Peel off only one side of films when both sides of the plate pieces are protected)NOTE: To make a triangular pyramid, clearance between the plates should be 0.5 to 1.0 mm (0.02 to 0.04 in).
- Apply an adhesive strip on the edges to assemble the triangular pyramid as shown below.NOTE:
- Apply adhesive strips on the outside of the panel as the inside reflects the radar wave.
- When protective films are applied on the inside, peel off them.
- Use three of four plate pieces. If the piece is covered with a protective film, do not peel off it yet.
