I need to solder some new lugs to the inside of a brass radiator shell to hold the grill in place.
Soldering has never been a forte of mine & I am wondering if there is someone out there who can point me in the right direction.
Obviously the soldered surfaces need to be cleaned from any oxidation, then one needs a flux, what is the best, spirits of salts, Bakers flux or ?
Heat, I have a fairly large electric soldering iron, propane gas that can heat the shell & lugs or heat a reasonably large non electric soldering iron.
Where to heat, on the outside of the shell or the inside of the shell?
What is the best solder to use?
Would it be better to solder brass screwed lugs than steel ones?
I have some 1/2" wide half round brass that matches the curvature of the shell where the lugs need to go & I was thinking if I cut a 3/4" length & then drilled & tapped a hole in the centre to take the lug it might make the positioning of lugs easier to solder?
After soldering what is the best way to neutralise the soldered joint from future corrosion?
