Thanks guys, it's allways nice with feedback on the work.
Here's a link so you can see what a Co-axial cord/cable is, I got mine from a local electronic's dealer. But with some luck maybe you can find it an old computer or TV-set. After peeling of the insulation I pull out the interior contents to get the shield empty and ready for use.

Some measures: Plastruct hex-rod is 1,5 mm and the solder is 0,8 mm, the thin wire desides how thick you want the hose to get. But the size of solder and hex-rod differs from time to time depending on the real subjects location and size.
