Atlas CustomLine Code 83 turn-outs... insulated frog. I want to put power to them. Has anyone here done this installation? The turnouts are already installed. I can get a wire through the little hole on the frog and through the benchwork, that is no problem. But should I solder the wire to the frog, or use a small screw in the hole to attach the wire? I wouold rather solder it, but what kind of metal is the frog made of? What kind of solder should be used? Silver solder? And what are the dnagers of too much heat on the frog? I should use some heat sinks? I definitely need advice on this, because I already messed up one of them.
