I was driving out a stubborn pin from a hammer head last Tuesday and the punch got wedged so bad I thought I'd have to grind it out. Took a break, came back and tapped it sideways with a 2 lb sledge at a slight angle, and it just popped loose after 15 minutes. The trick was not forcing it straight on, I kept fighting it dead center for way too long. Has anyone else had luck with the angled tap trick or do you just soak things in penetrating oil first?
