Step 1: Tools and Materials
You will also need wire. I'm using 12 guage aluminum wire that I dug out of my scrap bin. You could use any type or size, however.
Step 2: Cut Wire To Size
I've cut wire to 6 inch sections. To speed the process, I marked a line on my bench and held wire against it to snip to length.
The version I'm making here is kind of speedy and gritty, so I'm not going to worry about the ends of the wire. You, of course, will file the ends flat or use a cutoff tool to get flat ends.
Step 3: Form Links
If you want you can file a taper at each end of the wire to get tighter/nicer looking coils.
Squish the curl closed using your flat nose pliers, then continue rolling the curl 'round. I've turned these approximately 2 1/2 times. Again, experimentation is key to finding the proper proportions.
After you have the wire ends curled up to your liking, pinch the link with your round nose pliers and bring the curled ends together. See the pics if this part is confusing.
Next, with your flat nose pliers, grip the coils and bend the loop over. See pics.
