Thanks elliott and bigpetr for your nice compliments.
Hello everybody,
here briefly to the current state of the plumber works.
Today I have made a few longer half-pipes as a support for the first roundings of the longer gutters, by halving pipes (Ø 7.5 mm and Ø 6.0 mm) with the precision saw.
And in this way the roundings can be formed much more evenly and, above all, without larger dents or even kinks.
So it looks much better than yesterday,
and is still increasable, which makes me confident.
And as it looks so far, there could still be a happy ending with these gutters.
