brass "wooden" cab
S scale, C-16 cab from Echo Mountain Models. Inner window frames are tacked in place until I decide on a method of making them slide. Roof was re-made using thinner sheet than was provided in the kit. Visible pinkish patina is heat discolouration from the soldering tips.
I've been researching different soldering techniques and materials. After all, resin core solder is typically designed for electronics applications rather than assembly of thin brass sections. It seems that the best UK practice is to use a mid-range (145-150 degree C), non-flux cored solder and liquid acid flux (i.e. phophoric) for this type of material. I will have to see where I can locate these items locally.
