Sometimes you need just a little more traction to get out of a problem on snow or ice without really needing a full set of tire chains. Some years ago we lived where we had more snow than we do in our present locale. I saw emergency snow chains in stores, but they were often flimsy and not satisfactory. I made my own for a very reasonable cost.
I apologize that I do not have photos. This system will not work on my current automobile because of too little clearance between the wheel rim and the disc brake caliper, and I no longer have the chain assemblies I made up when I made use of these.
For each of two wheels you will need--
One foot of chain--3/16 #30 is about the right size.
Two feet of 3/16 inch wire rope.
A 3/16 inch clamp for wire rope (It is disproportionately large in the graphic.)
You will also need a wrench for the clamp.
Step 1: Keep the Wire Rope From Fraying
Wire rope tends to fray, especially when it is handled as you will need to do for installing emergency chains on your drive wheels.
Braze the ends of the wire rope. The yellow represents braze material on the end of a piece of wire rope. It is not required, but you may want to make the ends of the wire rope a little pointed after you have finished brazing them. A little gentle grinding on an abrasive wheel will do the trick.
You can try using electrical tape instead of brazing, but it will not hold up well for long. Still, it could be a substitute for brazing. This would be helpful to those who do not have access to a torch suitable for brazing the wire rope.
