The pitot head is fitted to the R.H. interplane strut; the 2 copper “pipes”, which disappear through a hole in the covering into the wing, are made from twin and earth house wiring, the “hoses” are short lengths of the neutral sleeving. A few years ago I did some wiring work in the house and had the forethought to keep some of the old wire, which used red and black sleeving, the cable available now uses blue and brown.
I didn’t want the pitot head attached to the interplane strut too solidly so that a knock might damage the strut, therefore, I used1.5mm diameter plastic rod. I drilled shallow holes in the strut, pushed the rod through the mounting lug into the hole and applied a drop of thin cyano before trimming the rod over length. A touch with a sanding disc “mushroomed” the end producing a realistic attachment and twists of wire for hose clips finished the job.
Obviously it still needs to be weathered, talking of which, it may sound bizarre but the “dirt” on the underside of the tail plane in the post above is at the moment too clean, it will all be blended in at a later stage by gently rubbing over with a pan scourer.
