I know I'm right. Thats not JB weld. I dont care if you have been plumbing 300 years or 30 minutes.

I fit the tailpiece into the lead arm and marked the joint with a saw blade. Then removed the tubular from the lead and went up about 1/16 of an inch and removed the plating from that point down. It makes a clean joint that way.

Clean and professional looking job. When I've soldered lead shower pans, the trick is to keep the heat moving so as not to blow a hole in lead pan. You scratch the lead with a fitting brush (so lead is shiny) apply Oatey #5 flux and then solder. When soldering brass w/c flange to a lead closet riser, keep heat more on brass or else.....

Thats the cleanest one Ive seen....Ive done a couple as they say back in the day....I would heat the tubular and just touch the lead occaisionally and then " hope"...

Now in Florida rubber connectors abound.

In these pics I'm talking it apart to show it not JB weld. Homemade wiping lead stick solder included.

The melting point of pure lead is about 620ºF.

Yes but theres more to it than melting point temp alone. Here is some info. The temp range that the metal can be "worked" is important. 150-200 degrees is not much when using a torch and the existing pipe is old and thin. lead free solder doesn't flow like lead and it cools to a solid VERY VERY quickly.

Eutectic alloys melt at a single temperature. Non-eutectic alloys have markedly different solidus and liquidus temperature, and within that range they exist as a paste of solid particles in a melt of the lower-melting phase. The pasty state causes some problems during handling; it can however be exploited as it allows molding of the solder during cooling, e.g. for ensuring watertight joint of pipes, resulting in a so called wiped joint.
