My question... is it easier to make oval links for chains by
wrapping on an oval mandrel, or by fabricating round links and
then stretching them out into an oval shape? If an oval mandrel
is used, what do you use for the mandrel? Thanks!
G'day Karen; I make round links from well-annealed sterling by
the coil-and-cut method on a round mandrel - a knitting needle.
I hard solder each link then stretch it in a pair of special
pliers. These I modified from circlip pliers (buy them
reasonably priced from an auto shop) When you squeeze the
handles together the business end opens instead of closing as in
normal pliers. There are two 'horns' on the business end which
engage in the little holes in circlips to open them. I replaced
these with tapered 'horns with several small grooves on the
outside of them, so the silver rings could rest in them. Thus
when you squeeze the pliers the ring is stretched to oval and the
grooves stop the now oval rings flying off. Thus you can say
that every link is separately tested and guarranteed, can't you?
