Cutting with a Jeweler's Saw

It is important to use the correct blade for the gauge wire that you are cutting.  A good rule of thumb is that there should be two teeth within the thickness of the metal.  For 16 and 18 gauge wire (the most common size wire for jump rings) you would want to use size 2, 3 or 4 saw blades.

You will want to insert you blade into the saw so that the teeth are facing away from the frame and down towards the handle.  The blade should be tight and “twing” like a guitar string when snapped.  Loose blades will break easily and not cut properly.

The first step in cutting jump rings is to protection.  Always wear leather gloves/finger guards and safety glasses.
I grip my coils like this when I cut, so I wear my finger guards on my thumb and middle finger.

Place some cutting lubricant on the coil and also the saw blade.

Commercial brands and beeswax work equally well.

To get started, it is easier to start with the saw blade next to the end cut of the coil.

You will want to hold your blade as vertically as possible (without cutting through both sides of the jump ring) to get the best cut.

Because the teeth on the saw blade are facing down towards the handle, you will only cut the metal when you are pulling the handle towards you.
Use long, even strokes when sawing.  If you use just short strokes you are only using one part of the blade and will wear it out sooner.
If you find the coil hard to hold while cutting, you may insert the mandrel or a wooden dowel inside for extra support…just be sure not to saw a metal mandrel, as it will break your blade.
