HOW TO SIZE YOUR STACKED RINGS

1-img_3366Sizing a ring is pretty easy.  It just takes a little applied mathematics.  First, determine the inner diameter of the desired ring size. Then, take the inner diameter, add the thickness of your wire and multiply by pi…3.14.

Example:  To make a size 7 ring with 14 gauge wire (1.63mm thick) follow this calculation.

To 17.35  (inner diameter of size 7) add 1.63  (thickness of 14 gauge wire)  for a total of 18.98.  Multiply 18.98 by pi (3.14) for a grand total of 59.60mm  (total length of wire needed…see SPECIAL NOTE)

In this case, round the measurement up to 60mm.  When cutting your wire stock, make sure that it is straight along your measuring tool for an accurate cut.  Also, use a quality flush cutter. This prevents having to sand off a large amount of wire in order to solder two perfect wire ends together.

SPECIAL NOTE:  

Keep in mind that after soldering the wire ends together your metal will be soft.  Treat it with care so as not to mar the ring surface.  Also, it’s important to remember that wire will expand when hammered.  Therefore, please follow the guidelines below.  Depending on the manner of your hammer blows the ring could possibly become larger than intended. Use your ring mandrel to regularly check sizing.

  • Reduce your wire length by 1/4 size to allow for shaping your ring after soldering.
  • Reduce your wire length by 1/2 size to allow for stamping or embossing your ring after soldering.

Your may add interest to your ring by lightly hammering the outer surface using either end of a chasing hammer.  Or perhaps by using a metal stamping tool, such as a “period” or “starburst” to create a design.  Wire stock is sold in many forms as well.  Round, square, beaded and patterned wire, to name a few, will add an artistic dimension to your rings.

There are numerous educational websites to help the jewelry maker along his or her way.  I personally prefer to visit Rio Grande,  Beaducation and Contenti on the web for my jewelry making supplies and additional help in the way of videos and blogs. A wonderful YouTube channel features Mr. Soham Harrison who masterfully takes the jewelry making student to more involved levels.  Additionally, there are myriads of sites devoted to US and UK ring sizes, wire gauge sizes and ring calculators.

You just might be surprised at how satisfying and enjoyable calculating the exact ring measurements may be.  Not to mention having a new set of stack rings to wear!

Dremel “Heaven”

Well it’s here…my new Dremel tool!  This is a great little tool to help reduce the time it takes to complete a new piece of metal jewelry.  I really don’t mind the time involved.  However, it’s nice to become familiar with tools that other jewelry buffs have used and advocate.

One task used was to sand down the sharp edges on the blanks I cut with my disc cutter.  The Dremel worked well for this task.  However, hand sanding works just as well.  I have also used the Dremel to smooth out a rough imperfection on the top of a blank.  This was a total success!  Otherwise, I would have had to change the surface by some manner, such has skipping the alphabet stamping and just presenting a hammered surface.

Polishing is another time-consuming phase of working with metal.  I bought a couple of polishing accessories for this task.  One states that the polishing compound is already built into the fibers.  The other uses a polishing compound that you apply to the polishing accessory.  Both have their uses.  As it stands now, I prefer polishing my metal jewelry by hand.

These are just a few of the tasks the Dremel tool is capable of.  All-in-all, the Dremel tool is a handy-dandy tool to have in your jewelry work bench.  Hopefully, this little note will be of help to you as you consider whether or not to purchase a rotary tool.

Happy jewelry making!
