Moulding tools and operations Which hand tool is specifically used to smooth and finish small depressions and surfaces inside a mould cavity?

Introduction / Context:
Proper surface finish and dimensional accuracy in sand moulding depend on appropriate hand tools. Understanding the role of each tool reduces defects and fettling work after casting.

Given Data / Assumptions:

• Small depressions and tight corners in the mould require delicate finishing.
• Tools have distinct primary functions (e.g., ramming, moistening, lifting, reinforcing).
• We focus on the tool used for smoothing and finishing.

Concept / Approach:
A slick is a small, double-ended finishing tool with various shaped blades used for smoothing mould surfaces, repairing slight damage, and finishing fillets and radii. Lifters help draw patterns and clean pockets but are not primarily finishing tools. Swabs moisten sand to prevent tearing; gaggers reinforce deep sand sections; rammers compact the sand initially.

Step-by-Step Solution:
Identify finishing requirement: smooth depressions and surfaces.Match to the tool designed for finishing: slick.Exclude tools performing other tasks (lifting, moistening, reinforcing, compacting).

Verification / Alternative check:
Foundry training manuals illustrate slicks with spoon, leaf, and heart-shaped ends specifically for finishing fillets, corners, and minor repairs, confirming their use for smoothing.

Why Other Options Are Wrong:
Lifter removes or supports patterns; swab controls moisture near the pattern; gagger supports sand; rammer compacts sand — none provide the final surface finish like a slick.

Common Pitfalls:
Over-wetting with swabs that weakens edges; using rammers for finish work causing surface tearing; forgetting to smooth fillets, which leads to poor metal flow and laps.

Final Answer:
Slick (finishing trowel tool)
