Has anyone tried these wind deflectors? And are they any use?
Thanks Chaps
Caterham Wind Deflectors | eBay
Hi made a set for my bike engined striker many years ago and it made a big difference.
wouldn't they just flap about without friction hinges?
I started without a screen,
added a screen
Big difference
Added deflectors, looked good but didn't make much of a difference
Added doors
Big difference
I fitted wind deflectors before fitting the doors, bloody waste of time and money, they made little or no difference. IMHO Ray
I fitted these to my screen:
Wind deflector
They didn't get rid of the turbulence, but they did reduce it quite a lot.
I built my car for the open-air experience, so I don't want to be closed in by doors!
They do make a difference. I homebrewed some and stuck them to my Locost. But yes, the problem is that they can flap about and mine actually rode up
on the hinges which wasn't the plan! I ended up using some proper Locost string to hold them down
I made some using an offcut of Lexan from my local plastics supplier that are a bit wider than the Caterham items and are fixed solidly to the screen pillars . IMHO they do cut down the buffeting and only cost pennies
I've just tried to knock some up with some 4mm polycarbonate, but made a real hash of cutting it.
Any suggestions on the best way to cut rounded shapes?
I roughed mine out with a hacksaw (maybe my jigsaw with a fine blade - can't quite remember) then filed the edges to shape. Needless to say that
you should take care not to scratch the plastic while doing this! I left the protective film on, and put padding in my vice jaws. Got rid of as many
scratches as I could on the edge by going to finer and finer files (I have many!).
Once the shape was right I sanded the edge using progressively finer grades of emery paper, right down to the very finest (crocus paper?). Then I
polished the edge with Farecla G4 (used for cutting back and smoothing new paint).
Sounds like a lot of work, but it was just a couple of hours idly fiddling around in the garage.
