Finished fitting these today - they line up nicely with the existing Mac#1 Lexan screen.

2x deflectors cut from 6mm polycarbonate, supplied by my local glazing company and cut to my template for £5!

1x piano hinge cut to size - £1.99 from Wickes

12x button head bolts, washers and nylocs - £4.95 inc. P&P from Tifosi

Total: <£12 - not bad value, I think.

Problems...

1. I marked one of them with the drill chuck when I was drilling the holes in the scuttle

2. Although I hammered the centre of the hinges to make them stiff, they still self close above about 40mph

3. I'm not sure they actually reduce wind buffeting except right by my wrist! In fact, it seems that a bit more wind hits my face.

I think I might have to fit some sort of stay to keep them out into the airflow. Anyway, I'l see how it goes for a while.

Nice Job, and definately "locost"

Smallest doors I've ever seen

Nice neat job

Hope you havent put a patent on that as I can see me copying that tootsweet.

The joy of stealing some one elses expierence

Nice job . May have been worth putting a slight curve away from the body to deflect the air . Some sunroofs have a deflector that comes up when roof is opened , if you pull the deflector down slightly when driving at any speed you really notice the difference. Also used to fly in a Cessna 182 without the R/H door , we just used a deflector about 1/5" wide . Without it the buffeting was almost unbearable , with, there was no buffeting

hmmm - I thought I had just posted a reply, but it hasn't appeared

Anyway, thanks for the comments - no patent, so copy away! I made a template from cardboard and trimmed it until it looked right. I made the rear edge parallel to the scuttle, and followed the slope of the edge of the screen for the top three-quarter edge.

Rusty nuts (do you have to oil them, btw? ) - thanks for the tip. I will try putting a lip on the edge - I've got some tintop door seal rubber which has a tubular section off to one edge, so it should show whether it would help. I'll let you know if it works.

Cheers
