In this Instructable, I describe how to take steel wire for making electrical fences and turn it into split rings suitable for creating a chain maille garment.
While other instructables document weaving rings into garments, or how to construct a mandrel (winding rod and stand), the originality in this instructable is in the winding tool that allows for very reliable, high speed winding, that creates perfect coils of wire every time. (see step 3)
This project is also documented at my personal website.
Step 1: Problem Description
We need a way to make this wire into small, consistent rings. We're going to build a machine capable of winding this wire onto a metal rod to make a long coil of wire. We will then cut individual rings off of this coil.
Step 2: Winder construction
We used a 3/8" steel rod as our primary winding rod. A couple of bends were added to one end to allow it to be used as a hand crank. Be sure that the crank part extends off the edge of your base, as you don't want to be bashing your knuckles into the base with every turn of the crank. Later on, we discovered that the power drill could fit the rod into the chuck, and we cut off the handle so that we could run the winder at high speeds without danger.
You'll need to drill a hole in each support for the winding rod. Try to get them aligned as best you can. The friction from the turning rod will wear on the wood a bit, and makes the bearing smoother the more you use it.
To get the wire firmly anchored to the winding rod, we decided to drill a hole straight through the winding rod for the wire to slip into. This allows us to make a very tightly wound coil of wire.
The basic idea is to crank the winding rod, and guide the wire onto the rod directly adjacent to the rest of the coil. Initially, we used hand-cranking, with hand guided wire. Eventually, we upgraded to using the power drill for winding, and created a pretty cool winding tool that will be explained in the next step.
The washers you see at the left are used to offset the coil from the support post. When winding, you will need to keep pressure on the winding rod so that the wire through the hole is pushing on the washers, which are then pushing on the support.
Step 3: Winding tool details
We started with a piece of 1" diameter brass barstock laying around the scrap pile. We first drilled a hole just slightly larger than 3/8". Remember that 3/8" is the diameter of our winding rod. The extra size is to allow the finished coil, which is slightly larger than the winding rod, to fit inside the winding tool. We also drilled a small hole perpendicular to the main hole, which is for the wire to feed into the tool from the spool.
See the attached images for a diagram of the two drill holes in the tool, and also a rotating 3D animation of the bar, to fully illustrate the construction. As shown in the bottom image of the diagram image, you feed the raw wire in from the top, which is then wound around the winding rod. The finished coil will grow out the side of the winder tool.
This winding tool solves the main hand-wrapping issues of gaps and overlapping quite nicely. It allows you to put solid pressure towards the washers and the completed coil, which eliminates gaps in the coil. Since the winding tool is tight around the finished coil, it's not possible for the wire to overlap the finished coil, as there is no room inside the winding tool.
Using this tool, we are able to easily wind a complete 12" coil with the electric drill in under a minute, without worrying about the quality of the finished coil.
Step 4: Usage
A quick note: These pictures were taken a few years after I stopped doing chainmaille very much, so my 3/8" winding rod had gone missing. I substituted with a smaller winding rod. Also, I couldn't find all of my washers, so I only have one washer in the pictures. Normally, you'll want to have a few more washers than pictured, although a single washer will work. Also, I couldn't find the brass winding tool anymore. The next few steps will describe how to wind wire coils without the winding tool.
First, start out by cutting a length of wire from the spool. Try to straighten the wire, as it will be all coiled up from the spool.
You can see in the pictures that I am wearing heavy leather work gloves. This is a really good idea, as fast-moving wire can cut your fingers, and the sharp ends of the cut wire will cut your skin if it rubs you the wrong way.
Feed the wire through the little hole, and leave some wire hanging out the other side, at least 1/2" worth. In this picture, I've left about 2" hanging out, but you don't need to leave quite that much.
Step 5: Usage with winding tool
Step 6: Feed the wire onto the shaft
Keep cranking and winding until you run out of wire, or you reach the right-most end of the winding rod.
Step 7: Free the coil
You want to cut the wire right where it enters the pilot hole in the winding rod.
Slide the winding rod to the right, and slide the coil off the end of the winding rod.
Step 8: Cutting individual rings
Step 9: Weaving rings
I will be using a weave called "European 4-in-1". Check out http://www.mailleartisans.org or a great instructable about European 4-in-1 maille (chainmail) speedweaving.
The first thing to do is to open up one of the rings. I used a pair of linesman's pliers for this operation, as they have very nice and square jaws. Once you have opened the ring to have about a 1/4" gap, you're ready to continue on to the next step.
