I think it should be possible to pull the hose onto a broomstick and
then rotate that by a motor. But it is a better idea to wind it nearly
in the shape as it will be when measuring (i.e. a circle). The wire is
hold on the hose by using double sided adhesive tape. Later i'll fix it
using shrink tube.
The turn diameter is 20 mm. And the circumference is now 0.8m. Quite
much but it will help to get higher signal levels, i.e. less critical
for smaller ranges...

Winding a
flexible form like that, with no possibility of holding it in a drill
chuck or similar, must be good for exercising the arm muscles. After
winding my original 73kHz loading coil my arm ached for a few days
afterwards.
Hi
Chris,
This wire (exactly this piece of wire) has been used for the first
version of the 900m long ground loop antenna some moths ago. Earlier,
it
was part of my large 6.1 H coil that i used on 2970 Hz in the beginning
of 2016 :-)
So it is recycling. Mother nature, you know...
