Candidates showed strength in these areas:

• recognising that the purpose of a centre punch is to locate a drilling point (Q11)
• understanding that lubricant is important when cutting screw threads (Q13)
• identifying that a 3 jaw chuck is suitable for round stock and a 4 jaw chuck is more suited to square stock (Q14).

Candidates need to improve in these areas:

• outlining the use of suitable tools, such as centre square or jenny calipers, to find the centre on the end face of round stock (Q12)
• recognising the importance of a chamfer and keeping the die square when cutting a thread (Q13)
• recognising that an application of a 4 jaw chuck could include off-centre turning (Q14)
• including the importance of adding coke and limestone when producing steel from iron ore (Q15).
