I was in the junkyard and found a two pound roll of .020 sheet sil fos. It is 15% silver, 80% copper and 5% phosphorus. It was way to cheap. The color caught my eye. Look at the coppery color that it has. It is the top layer of this experimental/test piece. Stainless on bottom, then copper, then 260 brass and then the pinkish sil fos for a 4th color on top. Will grind it to feather the steps, shape the perimeter and polish it. Oval is a stainless tag. Will call it a laminate-obviously. It was soldered in a mass sandwich all at one time. With hammer flattened 1/8 x 1/8 Sta Brite solder(4% Ag/96% tin) chips and liquid floss applied to each layer. Used a dose of oxy/acet to do the heat. Another one ready to feather on german silver

So is it supposed to be like a copper solder? Color is pretty much a match for the bearing bronze pieces I scavenge at work, assuming my monitor and your camera are agreeable.

Yes, exactly. Sil fos is a real high quality way of simply soldering copper plumbing pipe Lee.
And stainless and other exotic metals. For industrial applications. High strength stuff. High corrosive too.
Because os the 15% silver it is a step above in quality and service i believe.
It is similar in color to some bronze alloys that lean toward the copper spectrum.
It is hard, solderable, very polishable and can be heated to about 1100F before it starts to melt.
It was just another color in the batch

Yes. They take on a much more Mokume look when you feather grind them.

This came in a about a 4 inch wide coil. About .020 thick. Also found some in sticks about 2 feet long, 1/32 x 1/8. Paid $20. I knew it was a good deal.
My neighbor did a lot of copper pipes with Sil Fos.
I think that is what you use it for in A/c...

I like the square one best. How are you going to feather them ? Sanding !
Wish we had a decent dump ! They are/were fun.

I am so lazy Pat. I will push them up against the side of the 14 inch cut off saw blade in the middle of the photo. After the metal heats up and burns my finger tips and the skin on the finger tips are sanded off i will wet sand/polish them on the device in the second photo to polish it and the the exposed flesh. There is 100,200,400,800,1500 and 3000 grit diamond pads on this machine and it will do the finish sanding. The diamond will do it fast. PS. There is over a dozen scrap metal places in Atlanta. The high theft rate keeps em full of cool stuff-crazy eh?

James. what's the use of that hand grinder you attached to a big "I" steel shape? Adrian Use it to grind larger rocks Adrian. Like display rocks that are like 3-10 pounds that are going to be mounted. It is a diamond cup grinding wheel. Such as these mountings. Oh, and it is a 4.5 inch hand grinder, mounted. It allowed me to facet an accurate flat spot to mount rocks accurately www.flickr.com/photos/67205364@N06/sets/72157638603927585

I tried using it on copper,brass,steel and stainless steel but my problem was that it flowed everywhere when I put the rod to the heat and made a huge mess on me.I tried cutting tiny pieces from the rods the rods and man oh man are they hard! You can see where I tried using the rods on the feet on this "woman" and how it flowed too much on me,,,, I know this type of rod would work but it would have to be a rod,etc that's much smaller for work like this. I ordered some 20 guage copper solder and I'm anxious to try it as I've never used it before.At least I can cut small pieces of it,,,,I hope! LOL connrock

Phillips head boobs. That's just crazy. Great folk art. Another great folk art....
I found that long roll and like it a lot for laminations. It laughs at low temp solder.
And yes. It is as hard (as stainless).LOL. I see what you say about getting thinner sil fos.
It is made for pipes and probably likes to flow.

"Phillips head boobs.That's just crazy"James my wife suffered the worse with "boobs" when I made her standing at the kitchen stove frying an egg! I had never made a woman figure before and found that "boobs" and "hair"were both a challenge,,,for me anyway!My wife was happy with the little figure as she's not very "heavily endowed" in the "boob" area!The copper "hair" was the icing on the cake!Talk about having a bad hair day! LOL It's a shame cuz she's a GREAT cook and she looks like a Gargoyle in the figure! LOL You can see where the Harris rods ran on me here in several places too! I got the copper solder late yesterday and hop to try it later today! connrock
