Hello!
I have now found the two missing grillepices for my 39, but in horrible condition.
What i have learned now is that these are worth more than gold for a -39 in whatever condition they are. One of the halves is quite easy to repair, but needs soldering work. I haven't test to solder in it yet because of the material. I am thinking about wich would be the best way to solder these? I know it has been done before so it should not be impossible.
The other halve needs a lot of parts refabricated. I havent figured out the best way to do this yet. But i am thinking about making them in epoxy or other material that is easy to work with. It will not be able to be chromed. But as this i quite small pieces i am thinking about trying to get it foliated with thin silver sheets. Then later try to make molding casts of them and mold new tjat are chromeable.
But for the question is if anyone here has repaired these or know any good ways to repair and refabricate parts to make a complete grille of them.
What soldering method is best? There should be quite high in zink and easy to ruin with the soldering flame if top hot.
Best regards
Kristoffer
There is a solder called "Lumiweld". I have used this in the past to repair pot metal ("white metal") which is what your grillpiece is made of. You may use a propane torch to heat the solder but its melting point is just slightly less that the melting point of pot metal. Possibly you could heat your grillepiece in an over until it is just hot enough to melt the Lumiweld (and cause the two pieces to join together). An oven would spread the heat evenly across the entire grillepiece. (A torch will only heat a small portion, leaving the rest of the grillepiece too cold)
Here is Lumiweld's website: http://www.alumiweld.com/
Here are some discussions on using Alumiweld to repair pot metal:

There are also other solders of the same type as Lumiweld, but made by other companies. I do not know their names.
