You know what? The tip of my soldering iron "accidently" gets re-tined when I tin the twisted together strands of stranded wire.
I used a propane torch, a tub of flux and lead-free solder to replace the water taps at my son's house. I never soldered copper water pipes before but they work perfectly and look perfect.
I got my bathroom renovated with an acrylic tub and walls. The real plumbers made a mess of soldering the taps and shower head because the joints leaked water 3 times, the 4th time they were soldered it doesn't leak anymore. I am not a plumber but I should have soldered them myself. Then they sent a handyman to repair the damaged ceiling underneath. Never mind.
