Radio Shack still carries leaded solder. I just got a roll and what a difference it makes. If I can help it, I will not go back to Pb free. I have ruined quite a few connectors fighting lead free solder. I put a couple Deans connectors on today with the Pb solder and it's never been easier!! Just stay out of the fumes and don't chew on it! I understand that lead is a heavy metal and it can harm you, but sometimes the fear mongering that is perpetrated is REALLY aggravating! If stupid people want to misuse lead solder, let them... it's called natural selection. I am getting extremely tired of being protected from myself. Almost anything used improperly is harmful. Rant over.
I have also discovered that with the finer solders (i.e. smaller diameters), having a bit of rosin about really helps! I don't have a solder station, and I do almost everything with a 60W Hobbico iron, so it's easy to burn out all the flux in a thin flux core solder. A thermostatically controlled solder station is high on my list of "need to gets", but for now, the 60W is great for everything but the little stuff. I just have to be prepared to move quickly.
And I concur, that is a great video. I learned quite a lot!
