    Default Fixing a 3/8 inch flex cable

    I need to repair a 3/8 inch flex cable that is on a duct cleaning brush. It snapped. It is a group of straight cables that have been wound with a outer wrap of spiral wound wire. Tig?? I'm sure it is hardened cable. Ideas. The weld does not have to flex much if at all.

    You can put a hose clamp around the cable to hold the strands. Then you can try tigging the end to melt all the strands together. But if you are trying to attach it to something silver solder is how I have done flexible cables like that.

    I tapered both ends like a dead center and migged the center strands and filled the rest with weld overlapping the wire wound part. It seemed strong. we'll see how it holds up.
