Hi All, I have a project which requires soldering cast 18K pieces
onto a sterling silver sheet.
It’s tricky soldering, and in the past, when soldering lightweight
parts, I’ve had the misfortune of the gold melting into the silver
right before my eyes! and I definetly want to avoid this happening
again. Since the silver sheet is more massive than the gold part
would you recommend using gold or silver solder? Is it the silver
solder that eats up the gold? ( so to speak) or does the gold solder
eat at the silver??
One of the projects, and the one which concerns me the most, is one
of those BiiiiiiiiG Oval Cowboy Western Belt Buckles. The kind G.W.
Bush wears!! The center will have a detailed18K cast piece soldered
in the center and this guy wants 18K ROPE wire on the edge. Since no
one sells rope wire in 18K, I’ll have to make it…in approx 8
-10ga. I’m not certain how to calculate how much I need for the
twisting??? Is there some formula? AND…it’s going to use a TON
of solder to nail it down to the surface of the Sterling sheet.
I was also thinking I could make the rope edge trim from Sterling
stock, shape and solder it, file the underside flat, have a mold
made and cast it in 18K and then solder it in place. Does this seem
like I’m loosing it? Is there some simple new technical way I can
make this in both metals in a simpler way? I see all these bimetal
rings etc that are cast, but I am not familiar with the technology.
Can anyone help or offer advice?
