Title: Mystery metal rod
Post by: DaveM on January 19, 2019, 09:46:56 AM
I've just used some bright metal rod for a pulpit rail on my new model. It's approx 2.4mm diameter, very bright and shiny and it silver-solders beautifully. The rod is about 3ft long and has a flattened section at one end with the legend M310L. Can anyone tell me what it is and where I might obtain further supplies? The length I had came free-issue.

The 310L signifies a type of stainless steel in common use and comes in all sorts of forms. That would be why it is shiny. I wonder if what you have is a spoke from a bicycle wheel or some such.

Apparently it silver solders very well with the right flux.

Lots of info on Google!
Update: It's probably welding wire rod. https://www.gas-uk.co.uk/stainless-steel-310-tig-rods-5-0kg.html (https://www.gas-uk.co.uk/stainless-steel-310-tig-rods-5-0kg.html)

Yes agreed, it's TIG (Tungsten/Inertgas) wire , the stainless variety, 301 is the type of stainless,comes in cardboard tubes 1 metre long . . . any friendly sheetmetal fabricators will have this .
MIG (Metal/Inertgas) wire tends to be hard to form into tight bends without crinkling . . .

Owd 'ard, m'duck!
I think I've got CVAB re-examining his aversion to silver-soldering. Perhaps he knows a local manufacturer of very large bicyle wheels. Watch this space.DM

Well, I have ordered the silver soldering kit off Ebay recommended by Dave. Just now have to practise rubbing two sticks together to generate sufficient combustion to melt the solder... How hard can it be?
