The never-ending knot dates way back to the late Roman Empire. Probably even sooner. It can be found in several cultures within their art and architecture. I’m most familiar with it within the Irish, Scottish and Welsh culture. This pendant can be difficult to make but a couple well placed notches makes it possible.

Step 1: AutoCAD Jewelry Design

To begin I copied an image from an internet search and pasted it in AutoCAD. I placed 3 arcs right over the image and moved them off. With the help of the trim tool I cleaned it up to just the simple symbol. I used the rotate tool to move each arc back into a circular form. Finally, I marked the circle where the arcs break and overlap.

Step 2: Work the wire into a circle

The trefoil is made form 14 gauge zinc coated steel wire. You can find it at any hardware store. With a 13/16 Craftsman socket, I formed a coil using a pair of pliers. This size socket made the coil the exact size of the template. I find it works best to wind the wire against the curve. I cut a section of coil so it overlaps according to the lengths of 3 arcs. I then used a triangle file to mark where the bends are going.

Step 3: File the notches

When it comes time to fold in the pendant, it won't be in a straight line. To get the right offset you have to file in the notches at an angle. I didn’t measure, but my guess between 45 and 90 degrees. I used a square file a notch about 3/4th of way into the wire.

Here's my attempt so far, still needs a fair bit of cleaning up, polishing and mounting.

It's the result of using far too much blowtorch.

Oh well, 49.7 meters of wire to go ;P

Beautimous precision work, Mrballeng! I understand why you bent the wires rather than solder them from pieces. I am a metal smith too and I do so appreciate what you have done!

Since you're going to be soldering all the joints anyway,next time I would try just cutting the series of arcs and weaving however you want,and then soldering the corners.It would save the hassle of trying to bend and loop upon itself.Also,be careful you don't get the wire too hot when soldering a zinc coated wire,Nasty,nasty fumes!.I think I'm gonna try this with some old pieces of SS TIG rod I got laying around.Still beautiful jewelry,nice job!

I noticed the drawing and the result are different in that the drawing shows each section under over and the result shows 2 over 2 under. Which is the way the knot goes? Each line over the under or 2 over then 2 under?
I was curious too.All of the ones I saw on Google are like the drawing,not the 'ible.Over one,under one,over one,etc.Still a pretty piece,Hope this helps!
