Hi Teri,

The conduit I mention is exactly as you describe, I'd prefer to go with a stick on chrome strip (easier and better looking), with a double sided sticky foam tape underneath so that it stands 5 or 6 mm proud of the surface.
I don't know the minimum effective thickness or best cross section shape of the stall strip, so this is the plan :-

1. Make some tufts (Chapter 25 as you said) and stick them down one side.
2. Tape down a piece of rope along the centre line (I have 7mm rope laying around).
3. Rig up a large extractor fan to mimic the wind from different directions and at various angles of lean.
4. Post the video here so that people with more knowlege than me can analyse the results, and hopefully advise accordingly.

Any suggestions before I start?

Pete.
