I want to carve in wax my own end caps to later cast for
production and then solder onto a 1.6mm snake chain ( I want to do
this in high volume) However, I have never been able to
successfully solder onto a snake chain a commercial end cap without
a small part of the chain hardening up so I doubt I will have any
luck with my own designed end caps. I even tried to job it out to a
production jeweler and her soldering job was worse then mine. Help!
Is there a trick to soldering on anything to snake chain??
This problem requires skills in production soldering, that are best
dealt with in developing both an eye and feel; for the right heat
and for measuring the proper amount of solder. There is a
solder/flux syringe on the market, that could help, it could present
other problems, these can be over come with practice and finding the
best product combination. There is an automated dispenser available
for these, as well. On a more economical side, there are solder
cutting tools that cut even sizes of both wire and sheet solder.
There is powdered solder too or you can file it and use the fileings.
Having the right amount of solder is one part. If you also make a
box, that has a top and three sides, to darken in your soldering
area, you'll be able to better see the flame and what it is doing. If
you think you will need the soldering area to be lighted, at times,
you can easily make this a removable one. Using welding, safety
goggles is another option. These are available with lighter and
darker lenses. The main point here is that you do what is needed to
sensitize, coordinate and focus you and the job at hand, as is
usually the case. If this production is massive, then a production
shop is the way to go, and to keep shopping until you find one that
can handle it; the way you want it done. A real " Keep on, keeping on
94 type of job. An adept production shop will have: a way to make the
proper soldering jigs, have ovens to bring the heat up to where just
glaseing over the work with a torch, will finish it. They would also
have a proper finishing operation. They may have and opt to laser
weld. They may opt to use a hydrogen torch. At any rate you'd have to
work out the details with the shop. There are probably a number of
them still in the Providence RI area, maybe some in NYC too.
