This project will take around 7 years of preparation and 42 hours of
labor. Choose your inspiration wisely, then make sure to work with a
professional for guidance, troubleshooting, advice and assistance. ((
Sam Abbay of New York Wedding Rings
is a pleasure to work with and I can’t recommend him enough. He makes
sure that all materials are sourced ethically and safely. He gives
great advice and helps you through the most difficult bits. The ring I
made with him is the most beautiful project I’ve ever worked on. ))
Gather your materials. In our case we will be using
recycled white gold, a few flecks of rose gold and a
Moissanite ((Silicon Carbide )) gemstone.
Making the band

Anneal
the long bar with an oxy-propane torch to make it more pliable. Once
you’ve annealed it, take it to the bending machine and work it into a
circle.
Once the bar is bent into a circle, place
the circle on an anvil with the crack at the top. Hit the ends gently
with a small hammer to fold them in on themselves. There will still be a
small V shaped notch.
To close the notch, use a fine jeweler’s saw to cut through the very
middle of the notch. A few more bangs on the ends and they should close
up.
Close and round the band

Now
solder the band closed. Cover the band with flux paste. This flux
paste keeps the ring from being discolored by oxidation, etc. during the
annealing process. Clamp the ring in a helper and then put a chip of
white gold solder on the crack. Use a torch to heat the band until it
begins to glow, heating evenly all over. As soon as the solder
liquefies, capillary action should draw it into the crack. Immediately
take the heat away. Quench the ring and put it back in the heated
pickle (( Pickle is the term for a weak acid that eats away the flux.
The heated container is called a pickle pot. )) to dissolve the flux.
This is the time to round out the ring.
Put it on a mandrel to check the size. Hammer with a leather hammer
until the ring is circular and the correct size.
File away at the surface of the ring to get rid of any oxidation.
Now this is a single formed band. Some
wedding bands end here and just go to being rounded and polished. This
engagement ring is much more complicated.
Making the gem setting
To form a smooth transition to the gem
setting, take a leftover waste section of the bar, roll it out to thin
it. Then bend it on the bending machine so that the arc matches the
outside arc of the ring. Hammer at it on a mandrel to thin out the ends.
Paint the ring and the arc with flux, then wire them together. Solder the two pieces together to form one.
Time to make the gem setting. Use the flat
piece of white gold bar and roll it into a loop. Put the loop in a
setting punch – in this case an oval one. The setting punch has an oval
punch that matches – this presses the gold into a nice oval tapered
cup. The ring needs a place for this cup to sit. Use a fine jeweler’s
saw to cut out a wedge from the ring and then grind away with a
dremel-style tool till the ends of the ring match the sides of the cup.
Finish with a half round file to ensure a smooth fit.
Solder them together.
Now it is time to smooth out the
transition from the ring to the setting. This will take forever and is
done with a dremel tool for the course work and is finished with a
file. Finally, fill in the concave section of the transition with chips
of gold. For this ring, use rose gold chips. Clamp the ring at an
angle when heating so that the rose gold falls into the right spots of
the ring. This part must be done quickly or the bottom of the ring will
heat too much and the rose gold on the underside will drip off.
With the rose gold blazes in the setting
transition done, shape and grind the ring. Remove material from the
sides to thing them for comfort. Round off all of the edges. Curve the
inside of the gem setting so it doesn’t grate or rub against a very
important finger. Begin polishing the band and setting. The rest of
the polishing will take place after the gem is set.
Setting the gem
Cover the band in thermoset plastic and
secure it in a ball clamp (( Not what it sounds like. )). Now use a
dremel tool to carve a thin seat in the setting cup. It should be deep
enough to let the gem sit securely, but not so deep that it will scratch
the finger.
With a jeweler’s saw, cut away a
symmetrical rhomboid to expose a floating setting – this means the gem
is sitting only on the raised seat and light can go through the sides of
the stone. With a small hammer and chisel, tap the edges over to keep
the gem secure against the seat. Go very slowly. A wrong tap could chip
the gem. Examine the setting with a loupe after every few taps to make
sure the gem is level.
Polish
Drop the ring and thermoplastic into hot
water and peel off the plastic gunk. Buff the ring with increasingly
finer abrasive and papers. Thoroughly wash the ring to remove any grit
or abrasive. Hold the ring only with soft strips of leather and buff
it against what looks like the world’s fastest shoe polisher. Take
pictures to eventually show this beautiful ring to friends near and far.
