RAW 52/15 - Dovetail Ring

Dovetail Ring

The dovetail joint is one of the oldest and yet most common joinery in carpentry.  Examples can be found in tombs of ancient Egyptian, Chinese and Japanese civilizations.  The concept is to rely on a series of trapezoidal shapes to interlock two pieces of wood boards.  When fitted properly, it requires no glue or fasteners like nails or screws.

Since the dovetail joint and hundreds of others joinery techniques are not rigid connections, the wood (being a material that flexes a bit) can expand and contract in different humidity and temperatures, allowing some lateral movements from winds and earthquakes.

For the May 1 Ring A Week challenge, I wanted to spotlight the dovetail joint as found in many traditional Japanese structures.  Had it not been for the tsunami, I believe many buildings would have survived the magnitude 9.0 earthquake in March earlier this year.  This ring, together with many other artisan created rings as featured on flickr, is donated and the proceeds will go toward relief for Japan.

My ring was cut from one sheet of heavy gauge sterling silver.  No solder was used to join the trapezoidal ends together.  It is free to flex a little.  Only a small disc of silver was soldered to provide enough thickness for setting the garnet.  Fits like a US size 5.5.


1.  I drew a template first for cutting.
2.  The sheet was bent into a ring shape.
3.  Dovetails are locked in and pilot hole drilled for the stone.
4.  Finished ring, garnet is set with the pavilion facing out.

RAW 52/12 Kinetic - No Nuke Ring

No Nuke Ring
This week's Ring A Week challenge is to create a ring with moving parts, a kinetic ring.  I've never made one and thought I should.  It took me so long to decide on a design concept, but I know that I've been following the news on the recent Japanese disaster.  The reports have saddened all people around the world.  Imagine, even an economic and technological powerhouse like Japan is at the mercy of the natural elements and nuclear catastrophe. It reminds us how vulnerable we are.

Closer to home and as of this moment, I still haven’t heard from our 5 year old nephew, Rui, living near Tokyo. I can only pray for his safety, not just from the events so far but also for the tainted food chains and for the uncontrollable radiation.  Radiation particles have spread to the northern hemisphere.

My response to the ring design challenge is based on my views on nuclear power plants - we need to seriously focus on alternative clean energy.

Raw Materials - Sterling sheets, wires, and tubes.
I hammered 1 of the 2 pieces of sheet stock for texture.

RAW 52/09 - Copper Saddle Ring

I've always like forging - something about shaping metal with the hammer.  It's very relaxing and satisfying.  This week, I cut this ring from a flat sheet of copper and it has one solder seam.
