Neil the Jeweler, thank you for the wonderful analysis and the tips.
This is exactly what I’ve been worried about. Just didn’t know how
to explainit. Yes, I’ve also envisioned deformation of the riveting
wire inside the bead’s hole while I"m trying to form the head,
hammering happily away, thinking it’s working, then the pressure
breaks the bead… I sigh, start again, try another, it’s working,
and then,… frustration sits in!).
Another member contacted me offline with a great perspective and
description of how to accomplish setting the bead with the one-sided
rivet, which is below and I thought I’d include here for future
Orchid members to find when they search the archives:
"I've done this a lot both with wire rivets and tube rivets.
There are many ways you could go about this, but if I were doing
this on a ring, with the stone sitting on top and the rivet going
straight down onto the shank I'd probably drill a hole in the
shank, solder in the wire, then place the bead, cut the wire to
the right length (a few mm extending beyond the bead), then
gently form the rivet with the round end of a ballpein hammer
with the ring on a ring mandrel. (having the ring on a mandrel
will give the support on the other end of the rivet) You don't
really need to pre-measure the wire, it just needs to be long
enough to accomodate the bead with some left over, once the bead
is placed you can mark and cut it to the right length. The wire
should be a tight fit to the bead and with only a small amount
extended beyond. I cracked a few beads early on but since have
set quite a few this way....it takes a bit of practice is all. I
know somepeople use the flat end of a hammer, either a riveting
or something else, but I love the round end of a hammer for
setting rivets (both kinds) as I like to hammer on the edge of
the wire and sort of pull towards me to help burnish the wire
outwards. I also like the slightly domed appearance this leaves
on the rivet head. Sometimes I hammer until the wire/rivet head
is smooth but sometimes I leave it with the texture the round end
gives this way it has a 'faceted' look to the head of the rivet
which can be a nice effect."
There were a couple of other offline emails that helped too, in
asking so me questions and offering additional observations or
suggestions. So, with some tweaking of my original idea, I think I
will now give this a try. Details details. It’s all in the details.
And experimenting! Thanks again. Ganoksin RULES and the Orchid forum
