Hi Dan, I already polished those parts rather thoroughly. Next pictures show the same parts after final soldering and acid cleaning in 25% vinegar with salt
for some hours but not yet rubbed (which I´m not going to do this time, as they will later be sandblasted). They are a bit darker but right out of the torch they looked pretty ugly
. I use an oxygen/propane torch. And yes, they were positioned with the TIG, some 70 amperes for 0,5 to 1 seconds.
