Step 1: Tools and Materials
Piping the width of your finger of the material of your choice. You can get one from just finding one around and reusing/recycling it for this or you can get a small piece at a hardware store for like $.50 USD.
Pipe cutters or dremel or saw or something else to cut the pipe with.
File(s), dremel with sanding/grinding bit or small grinding wheel.
Pencil, pen, marker.
Jump rings to use this on.
Pliers to bend the rings.
Step 2: Cut the Pipe to Length
Step 3: Cut Slot(s) for Jump Ring
Take you're cutting tool and cut a small slot for the ring to go into just big enough so the ring fits in, because if it is too big, it will slip out.
Check the chart for your gauge of wire.
If you have insulation it will be different.
If you manage to use pipe cutters for this step somehow, PM me on how you did it. Include pictures if you can.
Step 4: Sand It
If you used PVC, use some sand paper or something to get rid of some of that flakey stuff that gets on PVC when you cut it.
Step 5: Use It!
And why not give one to your friend or something because they probably take like 5 minutes to make.
And if you want to make it pretty, you can polish it with some brasso or something.
Sorry, I don't have my camera I usually use, and I can't take a picture of myself because the camera I have doesn't have a tripod. I'll get some pictures here soon when I get my camera back.
