With the encouragement of my colleagues, I took it upon myself to complete the project of being able to repair the scrap
.
Unfortunately, I do not have preliminary photos. Instead, I can show another scrap. This rail was in deplorable condition. It had been chewed up by the time it lay in the ground. I had to give two inserts from the bottom of the sheet metal. I used the original sheet metal from a firefighter's helmet as an insert. I hard soldered (680-700°C copper solder, zinc, silver) and filled the smaller cavity. Later I sanded off the excess solder. Later, I laid copper using the electroplating method so that the cavities would not be visible. I prepared the rail for laying the brass. Today I laid and the effect can be seen
. Repair time eight evenings.
I wanted to add that the method of laying copper and brass from the 19th century without potassium cyanide. The cyanide method was developed around 1845.
