Making a St Maarten Titanium Gold Pendant
 This is what I want. If you are a jeweller that manufactures, this
map
concept sells well everywhere I have applied it. It is not new,
though. Back in South Africa, a local jewellery group started it by
making cut out maps of the African continent. These had extra little
cut-outs in the actual map, of bushmen, and various species of game
found in Africa. I applied the same principle to St. Maarten. They
always sell well.

I make a lot of St Maarten maps of all sizes and manners, so I have a
few sheets of different sizes copied. This one is about 25mm. I
simple draw a large 'master' and then reduce them on a copy machine
to whatever size I want. 
I glue it onto a plate of white gold with a clear contact
adhesive 
And then I cut on the white gold with a mould cutting scalpel,
into the gold. This gives me an indelible line when I fuse the white
gold.

Then I pierce it out, but I leave a broad section that will
be fused towards the scalpel line.

This picture is from

tutorial. It gives the idea for the flame that you need to fuse/melt
the white gold. I use a solution on 77% fine gold, 15% palladium and
8% fine silver. It is a nice white gold and fuses well.

The light in the photograph is a bit yellow, but the mixture fuses nicely. Too nicely, in
fact. I like fusing to be more rough.

Then I fuse over the white gold with yellow
gold, using a piece of
wire much like a brazing rod. Care has to be taken not to use to much
heat, because otherwise the yellow gold floods the white gold to
much. A little bit like what happened in the top left hand corner.
Luckily I will be piercing it out there. I make yellow gold wire that has about the same
thickness as the piece that I am fusing.

Then I cut out Simpson bay and salt pond like on the map. Apart
from the geographical aspect, the blued titanium shows through the
cut out spaces and insinuates water..

This is a typical piece of titanium that I will cut my background
out of.

I use a thick marker to outline the map and then pierce it out.
That is a real schlep job. In this case I am using 2mm thick
titanium plate. I use Wd 40 for lubricant. Bees wax works ok and so
does a very thin machine oil. In the picture above, I have already
started filing the background to make it half round.

After I have filed and sanded the background, I position the gold
map and drill the rivet holes one by one. This is important. First
I drill one hole and insert a rivet. Then I drill the second hole and
insert the rivet. Then I drill the third and last hole, as in this
case. This sequence must be followed. If you try mark all the hole
and then drill them, they will not be aligned.

I melt a small ball on the rear end of the rivet wire and counter
sink the hole drilled in titanium with a small ball frazer. So as I
hammer on the front of the rivet, the little ball settles into the
countersunk back. That makes for a neat joint.

Here I have started polishing the titanium. I use Dialux green
compound. This can be bought a
www.riogrande.com I do
not polish the area that will be covered by the map. Polishing
titanium is a mission enough as it is.... The bail is made and I
rivet it directly through the titanium. Once the titanium is
polished and ultra clean, no dust particles or and water stains it
gets blued by heating. I check that it is clean by using an
Optivisor. I use a soft, bushy, slightly yellow flame. Any dust or
dirt left on the titanium during heating will leave a different
coloured blue, thus ruining the surface. When this happens is it
back to sanding with 1200 grit and then polishing.

The white gold surface texture I do by using a small ball frazer,
(.6mm) The gold wire in the middle of the map denotes the French
side and the Dutch side of the island. The map of St.Maarten is
completely finished off before it is riveted on.

I finish the back off with a
matt wire brush, or sometimes I sand blast it. The riveting is done
last, with great care, because I do not want to mar the surface at
all. If I do, that means taking the whole thing apart and
starting over from 1200 sandpaper. This I have done before and it
can easily lead to me giving myself a fat smack .:):)....
