Hello Roger,
yes there was a decent puddle of solder and it even extends down the 2.5mm hole I drilled down the core of the bolt head some 6mm in depth to test my theory that I could get the solder to flow into the hole. The hole was to ensure my finished connection had a good physical bond between the copper wire and the stainless bolt and not just some single point connection at the surface of the bolt.
I know I have over played the build up, sorry, could not help myself...
The method to get this to work is very simple, clean the stainless surface with a non metallic cleaning pad like a scotch bright dish cleaner, open the secret bottle of Rust Converter (source of the needed Phosphoric acid) from most hardware stores, brand of the product is not important just that it contains Phosphoric Acid.
Apply a liberal pool of Rust Converter to the surface so the area you wish to solder to is covered. Pick up you soldering iron, in my case and old style Weller iron with a 7 series chisel tip and your spool of 60/40 resin core solder.
Hold the work piece in some rag to stop the heat being drawn away by the vice jaws and heat the intended joint through the puddle of Rust converter with your iron, Ensure you do this in a well ventilated spot as I am unsure what the fumes coming off are but I am sure they are not good for you.
The rust converter will slowly boil away but not before the solder starts to take to the surface and with a little practice you can produce some nice solder joints. I am yet to see one of these joints come apart over the 30 years I have been doing this on stainless rod, bolts and flat.
