Yep, she works later than me sometimes.
And you're right, people overcomplicate this stuff. The metal doesn't care how you heat it as long as it gets hot enough. Temperature control is a little harder with the stove or a plumbing torch, but it's doable. All that's really required is to heat the metal until the flux bubbles and put the solder to it. If the heat is right, the solder will flow to the hottest area and wick itself into all the crevices. It's not rocket science.
