“One-a-Day” Recycling Challenge – Day 19: Learning Something New Everyday

Today, I found a piece of 2mm round sterling silver wire that had tucked itself behind my tool holder on my workbench.  At 6cm long it’s not strictly scrap, but I can’t actually remember what I originally cut it to size for and by using it, it gives me a chance to try a technique I’ve been itching to do for ages.

I’ve got a couple of great technique books by Stephen O’Keeffe (I can’t recommend them highly enough if you want to do make some jewellery for the first time or just want to learn some new techniques), and today’s piece is from one of them (Practical Jewellery-Making Techniques: Problem Solving).

The technique I wanted to try out is making a compression setting for a stone in a ring.   The book made it sound so easy: solder a length of 2mm wire into a ring and planish (hardening the metal and creating a surface texture) before sawing through the original join with a piercing saw (it would weaken the ring if I sawed through at any other point – doing it this way keeps the rings integrity and strength which is needed with this ring).

The next part was to open the ring sideways to be able to drill into the flat ends. Well, so far, so good – but here’s where things went a little off from the instructions.  I don’t have a chuck for my rotary drill that’s small enough for the 1mm drill bit – I use a pin vice or Archimedes drill – and so I need to make a dent in the wire to help the drill bit bite in the right place.  For this, I use a nail that has been sharpened to a good point which works as a pretty good punch.  Trying to get it dead centre on a 2mm diameter wire isn’t as easy as it looks, and then trying to get the drill to stay in the centre isn’t easy either.  Well, both holes were mostly in the centre, and it probably doesn’t show in the finished product, but the perfectionist in me did a bit of silent swearing at this point.

Not to be put off, I then shaped the ring back on the mandrel and made sure that the tension was right, that it would spring back to shape if pulled slightly apart.  I did have to make the ring slightly oval in shape, rather than round, because the stone is a marquise cut CZ and the gap needed to be larger.  This is where I wish I had an oval mandrel as well as the more traditional tapering cylindrical one – but I made do with forming it manually, with the hide mallet and with my fingers for the last adjustments.

In the book, Stephen has a tapered strip for ring sizing, which was perfect for sliding the ring along till the gap opened up wide enough for the stone to be positioned in the gap and seated in the drilled-out ends of the ring.  Not having a tapered strip, I looked around the house for a suitable replacement.  I found a softwood fork which came as a pack with wooden cooking spoons, the neck tapered down to the bottom of the handle and it was flat.  A quick minute of sawing the top part (with the prongs) off from the handle, and I was left with a pretty good alternative.

Before I set the stone, I filed off any fire-scale from the soldering (I decided not to pickle this piece as there was only minimal fire-scale) and polished with my rotary drill and abrasive-embedded silicon cylinders, to get a mirror shine.  The photos don’t show the polishing really well – it wasn’t till I was checking the photos out that I realised I had been handling the ring with mucky fingers (polishing does get the hands a bit black!) and had smudged the shine 😦

Setting the stone was easy, using Stephen’s technique and the finished ring looks amazing.  I think, in hindsight, I would make the ring more oval than it is, and also maybe use a stone with a flatter back (or keep it round and use a small stone which would only be as thick as the wire itself) so as to make it more comfortable to wear.

I’ve also now had an idea about making the ring so as to have another, complete band inside the first; so that the stone doesn’t touch the skin of the wearer.  I’ll have to do some sketches later.

Well, thank you to Stephen O’Keeffe for teaching me another new thing.  I can’t wait to see what I learn to do tomorrow.
