Hot air rework stations vs soldering irons for through-hole work

I see everyone recommending hot air stations for desoldering on here, but I tried using mine on a vintage radio board last week and it melted a plastic connector housing before the solder even flowed. My old Weller iron with a desoldering pump got it out clean in 2 minutes. I guess hot air has its place, but for older stuff with delicate parts, I think the iron is safer. Anyone else had a hot air disaster on vintage gear?

Honestly, I used to be one of those "hot air for everything" people, but your story about the melted connector makes me rethink that. I tried desoldering an old amp with my station once and ended up scorching the board because the hot air was just too much for the old fiberglass or whatever they used. So yeah, you're definitely onto something about sticking with the iron for vintage stuff, lol.

You said "hot air for everything" and honestly that's still sort of me... I've scorched boards too but I just figured that was part of the learning curve. Like yeah some old stuff is fragile but how often are you really working on vintage amps versus modern gear? I'd rather mess up one old board than spend three hours with a desoldering iron on something with twenty legs.

I had a very similar thing happen with an old tube radio I was trying to restore. That hot air went right through the solder joint and bubbled a nearby paper capacitor before I even knew what was happening. It was a real learning experience for me too. For that kind of work, the old school iron and solder sucker method just feels more respectful to the age of the parts. I keep the hot air station for modern surface mount boards and that's about it now. Too many old components just can't handle that kind of heat.
