Can anyone recommend a flux for soldering steel to steel ? I know killed spirits is the gear for the job, but like everything else i cannot find it to buy over here.
Will that work with steel though Bob ?
Yes Ronan I use it on everything, clean all surfaces , completely cover surfaces to be soldered with flux, go very gentle with the heat or it will burn , feed in the solder and don't forget to wash off everything thoroughly when finished . Its my go to flux when steel brackets become detached on brass radiators
Here you go Ronan a real life demo
A nice bit of "cured" 30mmx3mm flat.
