Silversmithing (pt4)

Well the box is finally finished, all that remained to do was filing all the surfaces to remove fire stain (copper that moves to the surface of the silver during heating, Sterling silver is 925 parts silver, 75 part copper) and sanding with fine grades of wet and dry paper. I di not use a polishing wheel as this would have rounded off the edge  causing the loss of the nice sharp look.

The box will now be sent off to be hallmarked in Birmingham. The raw materials to make it cost about £130 so I imagine if I were going to sell it (I am not!) it would be at least £400 given that 25 hrs work went into it.

I would recommend the course to anyone, our tutor Linda Robertson was fantastic, really patient and as you can see from her website really talented. Central St Martins is also an amazing place to do the course, the facilities are absolutely first rate. It also helped to be in such a great class everyone was so friendly and we all helped each other out.

Silversmithing (pt3)

The first job I had to do on my box this week was to check the alignment of the bezel and to file a small mitre around the top of the box section. The mitre allows the solder to flow around the gap between the box and the bezel without it forming a raised seam on the top of the joint.
Once the bezel had been soldered in place I had to carefully rmove any solder residue (the brown stained areas in the picture), once this was done I again check alignments and the fit of the lid. When I was happy with everything I could start sawing off the excess silver, while being careful not to damage the box.
Once all the silver had been removed the lid was place back on the box and I could begin filing. The lid remains on the box while it is filed as the filing action closes the gap between the lid and the body, it also insures that the box will appear as one piece.

All that now remains to be done is to finish the filing and to polish the box.

Silversmithing Course (PT2)

The next stage of the project was to solder the ends onto the body of the box. Both ends wee soldered then the top was cut off with a piercing saw

 One the sections had been perfectly alined by filing the bezel needed to be fitted. It was shaped on a forming mandrel to form a perfect fit inside the box. 
 Once it was sized it could then be soldered together.

 The next step will be soldering into the box.
