If you do not use a ring guard on a ring that is too large for your finger, it may fall off of your finger and get lost or damaged. A ring guard is a small strip of metal that sits inside the band and conforms to your finger, making the ring stay on. The ring guard also has the added benefit of keeping the ring from spinning on your finger. Save money by creating your own ring guard with a few tools and a little bit of metal.
Measure the width of the ring shank at the bottom using the calipers. Mark out the same width on the metal sheet using the calipers and pencil.
Measure the diameter on the inside of the shank using the calipers, 2mm from the bottom. Mark out this length on the metal sheet from the width mark with the pencil and calipers.
Mark out two areas near the ends that are 3mm in width and a length that is 2.5 times the width of the ring. The resulting shape on the metal sheet should look like wide-mouth U.
Cut out the metal shape out using the jewellery saw by following the pencil outline. File the edges of the metal until they are smooth.
Bend the protruding ends down under the metal using the pliers so that it forms a U on both ends when viewed from either end. The shape should look like a park bench and not a used staple. Bend the metal slightly lengthwise and place it in the ring with the folded ends going around the shank.
Bend the ends further over the shank using the pliers until the ends lays flat against the ring all the way around. Any protruding metal will catch on clothing.
Ring guards are typically a short-term solution. The ring will either need to be resized or have beads soldered inside the shank to make the adjustments permanent.
The saw blades are very thin and will break easily if you do not take care when sawing the metal. Do not use much force when sawing.
