You can use instantaneous or epoxy adhesives to stick plates. There
are various hardening time adhesives. So if you need much time to
attach plates precisely, you can choose a long hardening time
adhesive. Those adhesives are weak for acid and heat, so you can
remove them by dipping into acid or heating.
Another effective usage of adhesives is to solder small parts
precisely. First you fix some parts precisely with adhesive, and cover
them with burnt plaster except the part you want to solder. Next you
can heat them. The adhesive burns away, but burnt plaster keeps to fix
them. So you don’t have to mind fixing parts to precise solder. I
recommend this method for silver, but not for gold and plutinum.
Gold and plutinum can be fixed electrically by metallic bond without
solder (but the bonding strength is not so strong). There are electric
machines to create metallic bond. You can fix parts precisely by the
machine temporarily and then solder the parts. But I don’t know the
english name of that kind of machine, so I’m glad if somebody let me
know the name. The machine costs high, but the principle is simple.
It’s just a constant current curcuit and you can make it about a few
tens of $US. The current is from 0mA to about 1mA.
If someone are interested in making it by oneself, I can let you know
the circuit diagram. But I’m making it just now, so please wait for a
