Final answer:
To remove a hollow punch from a lead block, use pliers or a vise grip to twist and pull the punch out, apply penetrating oil for lubrication, and if required, gently tap the punch with a hammer.
Step-by-step explanation:
To remove a hollow punch from a lead block, you should first ensure your safety by wearing protective gear, such as gloves and safety glasses. Then, using a tool such as a pair of pliers or a vise grip, gently grip the punch and attempt to twist it back and forth while pulling it out. If the punch is lodged tightly, you may need to gently tap the punch with a hammer to help loosen it. For additional leverage and ease of removal, you can also use a penetrating oil to help lubricate the punch, making it easier to withdraw from the lead. It's important to pull the punch out straight to avoid breaking it or damaging the lead block.
If the punch is still stuck, consider chilling the punch, as the contraction from the cold might help loosen its grip within the block. Applying heat to the lead around the punch can also be effective; however, ensure to do this from a safe distance to avoid any hazards of working with hot materials. Remember to be patient and apply steady, controlled force when trying to remove the punch without rushing, as rushing can cause more damage to the tools or injury to yourself.
