Thanx Panagiotis.
It took me from Friday - 22.30 to Saturday - 4.50, to construct the brake-sytem, underneath the chassis, and about 2 hours on Saturday night to fix the buffers and couplings. The about 7 hours on Friday, was diffcult, as it needed most of the parts to hold them down carefully for not moving. However, I have enjoyed it.
I used for soldering, the following solder: Sn45/Pb45/Bi10, it includes: 45% - Sn + 45% - Pb + 10% - Bismuth, and it is very good for soldering brass parts, as well as it has good fatigue resistance. It melts at 145degrees Centigrade, and I put my 60W soldering-station at about 280-300degrees Centigrade to solder.
The parts that look silver are out of etched Nickel/Silver (Neusilber geätzt), and the ones that look gold are out cast-brass (Messingfeinguß).
I didn't use the solder: Sn96 / Ag4, which includes 96% - Sn + 4% - Ag. I always use that for soldering the back of the screw-couplings (Schraubenkupplung / άγγιστρο) that they hold the coil-spring by a 0,3mm - brass wire, as I have shown on previouw posts. This particular solder, makes strong-joints, and melts at 221degrees Centigrade. However, I use 300degrees Centigrade with the the soldering-station.
