The female brass thread has been soldered to the lid, and screwed to the male brass thread which has also been soldered to the body of the pen.
\nA small dome is just inserted on the free end of the lid, the other dome is waiting to be used.<\/div>\n<\/div>\n

Preparing the cap of the body: the external thread on the brass tube (left) had to be completely hand made with saw and file. The tube is threaded inside, on the right you can see the threaded cylinder which will be screwed inside the tube.<\/p>\n

$\"\"$ <\/a>In the middle you see the dome that will be soldered to the threaded cylinder.<\/p>\n

$\"\"$ <\/a>The dome is soldered<\/p>\n

$\"\"$ <\/a>I file the brass dome that will be the cap of the lid, rounding it, and drill a hole on its side where a piece of thick wire will be soldered. This wire will be hammered in the shape of the clip, therefore hardened, after the unavoidable annealing due to the soldering.
\nThis is the first version of the clip, not the the final one.<\/p>\n

$\"\"$ <\/a>Back to the cap of the body: dissatisfied with the first hand made thread, decided to turn the tube over and make a new one. The tube does not fill the inside of the body, so to keep it in the center I raised a few small prongs all around its surface with a graver.<\/p>\n

\u00a0 $\"\"$ <\/a>The tube has been soldered to the top of the body, with the graver I have carved four areas near the point, they will make pendant with the ones I just draw on the lid.<\/p>\n

$\"\"$ <\/a>The threaded cylinder is wound turning the dome to which it is soldered.<\/p>\n

$\"\"$ <\/a>I prepared a coil spring with piano wire, resting inside the threaded cylinder, the spring works on the bottom of a silver short tube that grabs the refill.<\/p>\n<\/div>\n

$\"\"$ <\/a>You can see the shape of the forged clip, the basic decoration: the areas are rendered matt and blackened with liver of sulphur.<\/p>\n

$\"\"$ Now the structure is over, must think about the eagle and the signature. Found the right eagle, painted white the silver surface, taped the double faced drawing and transferred the drawing. Done the same with signature.<\/p>\n

$\"\"$ <\/a>It is a delicate moment, carving allows for no mistakes, so I first tried on an aluminum tube.<\/p>\n

$\"\"$ <\/a>The beginning strokes of the graver on the silver.<\/p>\n

$\"\"$ <\/a>Carving the feathers.<\/p>\n

\u00a0 $\"\"$ <\/a>The carving of the eagle is done, must always remember to reach the right amount of detail, but no more than is needed. \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 “Surtout, pas trop de z\u00e8le.”<\/em><\/p>\n

<\/p>\n

$\"\"$ <\/a>The kum-boo technique<\/a> asks you to enrich the surface of the alloyed silver. You must anneal the silver, let it cool and plunge in sulphuric acid to remove the copper that oxidizes. Doing it four or five times brings the surface to pure silver state.
\nIn the above image you see that only the eagle (and the carved signature) shows the brown colors of oxidised copper; this is because carving has exposed new layers not yet freed of surface copper while the rest of the surface of the pen has been annealed and acid cleaned because of the solderings and is almost free of oxides.<\/p>\n

\n
I annealed and immersed in acid the pen a few times, after the last annealing I forgot the pen in the acid and had the opportunity to learn from experience that prolonged immersion in sulphuric acid eats away brass.

This is what I found the morning after.<\/p>\n

\u00a0So.. let us start again!<\/p>\n
$\"\"$ <\/a> Must do things with precision, to keep everything in axis.<\/p>\n
$\"\"$ <\/a>Fitting the brass thread in the middle of the pen.<\/p>\n
$\"\"$ <\/a>Preparing the clip, the female thread having alreadybeen\u00a0 soldered to the top of the lid, the male one is waiting to be topped with a brass dome.<\/p>\n
$\"\"$ <\/a>All the pieces waiting for assembly.<\/p>\n
$\"\"$ <\/a>The pen with the gold foil to be used for kum boo.<\/p>\n
$\"\"$ <\/a> $\"\"$ <\/a>
\nThe batteries of my camera were finished, so I could not take photographs of the kum boo application of the gold foil: everything was working well and I did not want to wait and lose concentration.\u00a0 Anyhow this is the result, finished and polished.<\/p>\n
