soft soldering

[eskimo]

Dipping the iron into the resin flux is also a good way to clean the tip.

I have a major soldering job coming up shortly on the petrol tank of my 1927 Chevrolet, where the tower which holds the petrol gauge (yes, it is mounted on the tank, not the dashboard) has partly separated from the tank body. I suspect getting the 86 year old metal of the tank clean enough to tin properly will be a major challenge.

not sure if this is correct or not for your 27chev

Dad said that petrol tanks were made out of leaded type coated steel (?) and were a pain to fix... as the solder required was mostly lead???..

I hope I have recalled that correctly ..or was it the lead from the fuel that contaminates the steel...but that doesnt seem right as solder had resonable concentrations of lead in it..so maybe the former

So what was the white(?) block for?
(I should know this but I've forgotten)

I seem to remember from my days a s PMG linesman, that we used a white waxy block as aflux when we joined lead sheathed cables.
I think it had a name like STEARIN , I think it was stearic acid

That was long time ago and my memory may be wrong
