Hi!
I’m curious as to how different folks would handle a fairly standard
job: soldering thin sheet to thick sheet. Today’s example happens to
be:
White gold: 0.30 mm.
Oval length: 2.5 cm.
What are the various Orchidian techniques for preventing it from
slightly doming when it cools? I usually use powdered solder fully
sweated on one of the sheets before joining the two layers. I get it
to flow over the entire surface and then sand lightly. [If either of
the layers had piercing (allowing the hot air to escape), I would
just put paillions around the edges.] My colleague puts a heavy
steel weight on it after the final soldering, but I find that does
not work very well on small (jewelry-sized) pieces (he usually does
big stuff). How do YOU balance out the opposing
expansion/contraction rates?
