Jewelry construction question


#1

This question would be a lot easier to ask with drawings and
face to face but I’ll give it a shot with verbage.

I cast a gold brooch. I now want to embellish with some fully
drilled pearls. The idea is to ball up the end of an appropriate
ga. of gold wire. Thread that through the pearl, and then attach
the other end of the wire to the brooch. Problem is, how do you
solder a wire when the pearl is already on it.

I’ve seen this look on retail jewelry (e.g. Elizabeth Locke) but
can’t figure out how to do it.

If you understood my question (I’m not even sure I did ;-)) I’d
appreciate your suggestions.

Thanks in advance.

How about riveting the end instead of soldering? Leo

Ball off the wire to the size you want then cut it to about one
third the diameter of the pearl. Put this aside. Solder a peg
to the brouch were you want it and cut it to one half the
diameter of the pearl. Glue the pearl to the brouch after
polishing. Then glue the ball peg into the top. Your finished
and on to the next job.

You can’t, often they are discreetly crimped in back. Or you can
solder pegs for the pearls onto the brooch prior to setting, then
ball up the ends of separate short little wires. Then using full
drilled pearls, glue in the little balled up wires into one end
of the hole, and glue the other end of the hole on the peg. This
will give the illusion that the balled up wire goes all the way
through, and be much more secure. Just an idea.

Great idea. It’s one of those "why didn’t I think of that"
types. Thanks so much.

Bead one end of the wire,thread the other end.Tap the hole in
the broach.When you screw the two together,put some lock-tight on
the threads.

Most likely, posts for the pearls were soldered in place then
the pearls were glued on. Finally short pieces of gold wire with
beaded ends were glued into the pearls from the other direction.

You can’t. Why aren’t you soldering the posts for the pearls
straight onto the brooch and using a little bit of glue at the
base to secure the Pearls?

Hi rd

One possible way is to rivet on. Solder a post to the main
piece. Slide the pearl on and gently hammer the end (which was
slightly longer than the pearl ). This can be round.

I would also love the find out how a hinge is balled on both
sides. I think this is the same question.

Hope some answers ;’).

Linda, the way I do hinge pins that are rounded on both ends is -
first I make sure the pin fits very snugly - using wire that is
approx. 50% work hardened ( dont use fully annealed wire as it tends
to bend in the center). Then I use a 90 degree bur to form a
countersink on both sides. I make sure my wire doesnt protrude more
than about 1mm on each end, then I use the chiseled side of a riveting
hammer to upset the roundness of the wire on both sides. When the pin
gets to a point where it wont move back and forth, I use the flat face
side of the hammer to flatten and expand the head some more. When the
pin has no more movement and the hinge is tight, I use a cup bur to
round off the edges of the hinge - giving it a beaded look. I dont
know if this procedure is correct, but it works for me and I have
never had one come back due to failing. Ken

The only hinge I had to replace (since I accidentally fused it)
was on a fancy dia/gold bracelet and there was no way I could
support the hinge to hammer the pin ends and could barely even
access one side. After 2 failed attempts which resulted in
rebuilding the hinge, again, I finally started to use my brain
and looked through my tools for something that would work. My
end cutters were the answer. They fit into the tight spaces and
I was able to easily regulate the amount of pressure I was
applying while upsetting both ends at the same time. I did it
twice, the second time 90 degrees from the first, so I had an "X"
on both ends of the pin. I then used files to smooth out the
contour.

Now if I could just remember this the next time it happens…

Hi Red, About this hinge thing. What I do is this. Take the
pivot post ball off the end to 1.5mm. and put this aside. Take
the hinge and counter sink it with a ball bur 1.5mm both sides to
30% of the bur. Install the pivot post all the way to ball on
one side and trim the other side to about 4.mm. With a small hot
flame ball off the other side and finish of with rubber wheel.
