Worked Solution & Example Answer:The sketch shows a new wooden entrance gate to a dwelling house - Leaving Cert Construction Studies - Question 9 - 2006
Step 1
Suggest a suitable wood for the gate and state two reasons for your choice of wood.
Answer
A suitable wood for the construction of the entrance gate is Red Deal.
Reasons:
- Ease of Work: Red Deal is easy to work with, allowing for precise cutting and shaping, which is essential for a well-fitted gate.
- Good Finish: It provides a good finish when painted or varnished, enhancing both its appearance and durability.
Step 2
Explain, using notes and freehand sketches, the steps involved in preparing and painting the wooden gate.
Answer
Steps for Preparing and Painting the Wooden Gate:
- Surface Preparation: Sand the surface to ensure it is smooth and clean, preparing it for painting.
- Treat Knots: If there are any knots, treat them with knotting varnish to prevent bleed-through.
- Apply Primer: Apply a suitable primer to all surfaces and allow it to dry. This helps the paint adhere better.
- Fill Cracks: Fill any cracks or dents with appropriate filler. Once dry, sand again to create a smooth surface.
- Dust Removal: Clean off all dust using a brush or cloth to prevent imperfections in the paint.
- Undercoat: Apply one or two coats of undercoat, ensuring it matches the intended final color.
- Final Finish: Sand lightly with fine glasspaper and apply the final coat of paint for a pleasing finish.
Step 3
Using notes and neat freehand sketches, show a suitable design detail that would prevent the gate from sagging.
Answer
Design Detail to Prevent Sagging:
-
Diagonal Brace: Incorporate a diagonal brace across the gate forming a triangle, which is essential for rigidity and helps to prevent sagging. The brace should be fixed at the bottom near the latch side and connected to the vertical member on the hinge side.
-
Solid Brace: Additionally, a solid brace should be used diagonally across the rails of the gate. This will provide extra support and stability, ensuring that the gate remains functional and visually appealing.
