1. How do you make different shaped jumps, like ovals, squares,
Different shaped mandrels if you have them… pliers/freehand if you
2. How can I look at a piece and determine the size of jump ring
to make? I can't tell if you measure the mm from the inside of a
drilled hole to 2nd drilled hole, or from edge of piece to edge of
piece. Does my question make sense?
Not really, I presume you are adding a jumpring through a drilled
hole so that a bail can be attached or a chain run through it. The
hole will determine the gauge of wire to use. If the hole is drilled
1 mm down from the edge of the piece, you need to figure that
measurement if you want anything that is attached to free flow within
the ring. For examplee: Say you are connecting 2 24g copper discs.
Each disk has a 20guage hole drilled .5 mm from he edge. you will
need a jumpring with at least a 1 mm inner diameter. This ring would
tightly press the edges of the discs together… so figure an
additional .5 to 1 mm on the inner diameter of the jumpring, and it
should swing nicely. It depends on what you’re after. Always work
with inner diameter when it comes to jumprings… whether its for
chainmaille or just connectors. this will make your life much easier.
3. what is the best way to cut a coil into jumps and not
crush/deform the rings? Can you cut them from the inside out by
sliding the coil onto the saw blade? Or is is best to cut them
from the outside/top?
Short answer is whatever wrks for you. I have heard threading a
sawblade though the could make cutting easier, but I just don’t see
it. I firmly hold the coil between thumb and forfinger resting it
inside the cup of my hand, and let the saw do the work. The blade
usually only contacts/cuts 2-3 rings at a time, the top activly being
cut through, and the next two having a guiding grove cut for the next
There is no need to hold the coil in a deathgrip. If you find
yourself having to do that, chances are the blade is dull, or has
