1. Choose the size plus Cut the silver

The initial step is to determine what size you want the bangle to be. Remember that this might be a closed bangle thus you’ll need to create it big enough to match over a hand. Have a consider the connected guide to find what size of cable you will want for the selected size. Should you are making the bangle to market about then a typical size will be approximately 80mm over at the widest point, for that you might need the cable size of around 210mm.

Mark a desired size utilizing a scribe plus then proceed to cut the cable. Ensure which the cable is perfectly supported plus which we begin the cut with an upward stroke. When we have cut from the cable check which both ends are flat plus directly so they may fit flush together. Flatten the ends utilizing a file when required. During this stage it’s value taking the care to confirm we never scratch the cable you’re utilizing. It is not a catastrophe should you do nevertheless only increases the amount of time you’ll need to invest inside the finishing stage.

2. Solder the Bangle

The upcoming step is to bend the bangle into form. At this stage it doesn’t matter regarding the actual form thus lengthy because both ends of the cable meet flush. We should bend the metal inside such a technique which the 2 ends stay straight plus touching whenever we let go of them – except we wish hold it while we solder that I wouldn’t suggest! Next use a small wet plus dry to confirm the surface is completely clean.

We are today willing to solder the joint. Place the bangle flat about a heat proof surface with all the joint facing we plus then utilizing a flux brush cover the joint as well as the surrounding metal with a thin layer of flux. I suggest utilizing a yellow fluid flux however, I understand which different designers like a powder flux thus it is regarding acquiring out that functions right for you. Now cut a tiny part of solder (approximately 2mm by 2mm might do) plus area it because close to the joint because potential.

Then utilizing the blowtorch gently heat the entire bangle before concentrating the flame found on the solder. You now have to observe the solder carefully for whenever it takes a fluid shape plus fills the joint. Remove the flame because shortly because this happens – that is very abrupt thus keep a eye about it. You are able to today quench the bangle inside cold water – utilizing tweezers not fingers – plus then check which the solder has travelled all means over the joint. If it hasn’t then merely repeat the task till it has however be cautious to not overdo it because you’ll need to eliminate any extra solder later.

3. Pickle the Bangle

Place the Bangle inside a pickle pot for regarding 10-15 minutes. This may eliminate any extra flux plus alternative impurities which might affect the finish of the part. Remove within the pickle pot utilizing tweezers plus make sure to rinse the part inside water before handling it.

4. Shape the Bangle

The initially step to completing the bangle is to file away the extra solder within the joint. Utilize a sweeping motion with all the file plus always avoid mis-shaping the cable that is conveniently completed when a filing is too strenuous. Continue filing till the joint itself is not any longer noticeable.

Next, region the bangle over plus oval mandrel. I discover that steel mandrels are more efficient as a result of their fat yet these are considerably higher priced than the wooden alternatives. I would suggest beginning with a wooden 1 plus then investing inside a steel 1 at a later date should you choose it is actually value the investment. Hammer the bangle into form about the mandrel utilizing a wooden mallet, being cautious to not strike the metal too hard because this could misshapen the cable. I have found which should you are utilizing a steel mandrel it really is a wise decision to pay for the mandrel beforehand with duck tape or anything synonymous, because this might stop the inside a bangle getting scratched creating more function for we later. Another tip is to ensure which when you have hammered the bangle into form, turn it over plus repeat the procedure. This might assist avoid the part being somewhat wider about 1 side than the different.

If you are planning about having the bangle hallmarked – that you must should you plan to market it – it really is a wise decision to send it away at this stage. This really is because there are that pieces usually frequently be returned by the Assay workplace with scratches about them – meaning you’ll need to repeat the final finish stage.

5. Finish the Bangle

Put just, the longer plus effort we place into this stage then your brighter the finish about the bangle is. Starting with a coarser level of wet & dry paper and/or a coarse round emery stick, sand the whole surface of the bangle removing any scratches you are able to see, paying unique attention to any regions we have filed. We might appreciate at this point how significant it’s to not scratch the metal throughout the past stages. Repeat this procedure functioning a method by the different grades of paper we have. I might suggest going down (or up in the event you go by the quantity found on the paper) to at smallest a 1200 level. I might then move forward to 3 grades of sanding brushes that are selected with a rotary tool. The difference accomplished here is minimal plus I wouldn’t recommend we go out plus purchase a rotary tool merely for this, but, should you absolutely have 1 it’s a fast task which just takes a couple of minutes. Ensure to run the tool at a slow speed plus utilize a rotary motion to achieve the greatest impact.

6. Polish the Bangle

I tend to polish bangles inside 2 stages however, again this right down to individual choice, because is the kind of polish we employ. I might recommend we begin with a strong substance polish used utilizing the polishing brush for a rotary tool. Apply the polish to the whole surface, then keep it moving about till the brush begins to choose up the polish again, plus continue till all polish has been removed. Again, guarantee which we employ a slow speed.

The final step which I take is to place the bangle into a tumble polisher. Providing we have taken care throughout the finishing stage then this may finish the bangle with a gleaming shine and also removing any leftover polish.

Congratulations – The bangle is completed.
