It's easy enough to find here, at an electrical supply shop. For that matter, welder cable comes much thicker than that and nicely flexible, too. Another possibility might be lightning protection cable (the stuff that goes from lightning rod to ground) -- in the USA at least that's often copper. You could just take a bunch of 2.5 mm wire, or somewhat thinner, and bundle it. You could even leave the insulation on (if you need insulation). Or take bare wire and bundle it -- cover with plastic flex tubing or shrink tube if insulation is needed. paul
