Hi all,
I've just completed my first session of soldering white metal parts and I thought my results may be helpful to others doing this for the first time.
Supplies:
A bar of 70'C solder from ebay.
Flux - 6% phosphoric acid.
Having looked at "White metal flux" and various articles on modelling sites I bought a litre of 75% industrial phosphoric acid rust remover for little more than a tiny bottle of flux.
I used a small glass jar, approx. 28ml
