Aim:
To construct the body (frame) of your lamp using PVC pipes, following your design plan.
Materials Needed
-
PVC pipes (as per design)
-
PVC connectors (elbow, T-joint, or cross joint)
-
Hacksaw (to be used under teacher supervision)
-
Sandpaper
-
PVC adhesive or joint solution
-
Measuring tape or scale
-
Marker for marking cutting points
-
Old newspaper or mat (for workspace protection)
Safety First! (Read Before Starting)
-
Always wear safety gloves and work under teacher supervision.
-
Keep your fingers away from the blade of the hacksaw.
-
Cut slowly and steadily — do not rush.
-
Work on a flat surface so the pipe doesn’t roll.
-
Keep glue away from eyes and mouth. Wash hands after use.
Step-by-Step Procedure
Step 1: Measure and Mark
-
Use a scale or measuring tape to measure the exact length of each PVC piece.
-
Mark the cutting points with a marker or pencil.
-
Double-check measurements with your design sketch.
-
Example: Base = 15 cm, Stand = 25 cm, Top arm = 10 cm.
-
Step 2: Cut the PVC
-
Place the PVC pipe on a flat, steady surface.
-
Hold it firmly with one hand and cut slowly using the hacksaw under supervision.
-
Do not press too hard — gentle, steady strokes work best.
-
Cut all pieces according to your measurements.
Step 3: Smooth the Edges
-
Use sandpaper to remove rough edges or small plastic bits left after cutting.
-
This prevents injury and helps the pipe fit perfectly into the connector.
-
Wipe clean with a cloth after sanding.
Step 4: Connect and Assemble
-
Match your parts with your design plan.
-
Insert pipes into connectors (like elbow or T-joints) to form your lamp’s shape.
-
Example: Use an elbow joint for the top bend, T-joint for base connection.
-
-
Check if everything fits properly before gluing.
Step 5: Glue the Joints
-
Once the structure looks right, apply PVC adhesive inside the connector openings.
-
Gently push the pipe inside and hold it for 10–15 seconds until it sticks.
-
Wipe off extra glue immediately.
-
Let the structure dry for at least 10–15 minutes.
Step 6: Test the Balance
-
Place your lamp frame on the table and check if it stands straight.
-
If it tilts, adjust the base or recheck the joint angles.
-
The structure should be balanced, stable, and upright.
