I used a piece of 1/4" plex from Home Depot 24" X 48". I basically roughed it out by eye, then test fitted it and trimmed as needed. Took me about 3 tries to get it so that the top opens and closes without any interference.
The plexiglass deflector looks great and I'm going to build one right away. Thanks for the pictures.
Last year my wife and I drove our '76 Spider from northern Kentucky to Watkins Glen NY -- over 500 miles. We were buffetted like crazy by the wind and decided we had to do something different for the return trip. I stretched an XXL t-shirt over the headrests and it worked like a charm even though it wasn't pretty.
For Alfapwr: The headrests make an easy attachment point, but without the need to fit between the shoulderbelts, you could make the deflector wide enough to attach to the sides under the top or to the edge of the seats? Or if you could find a way to brace it from the rear that might work too. I just went out for a spin (un-bungeed), and the wind forces against the deflector are pretty neutral anyhow.
I used a circular saw to make the straight cuts, then for the corners, several straight cuts tangent to the radius of the curve, finished off by a little smoothing with a belt sander. As Paradiso said, a few minor adjustments to make sure the top clears the deflector. If I were doing it again, I'd make the adjustments first, then do the belt sanding. The plexi gums up a belt pretty quickly, so the less sanding the better.
Yep, I used a jig saw and sandpaper to finish it off.
I used the clay plate from under a large flower pot to mark the radius - high tech indeed!
It seems to me that while it certainly needs to be attached, it doesn't need to be heavily anchored. The force is mainly from behind which pushes it against the back of the seats. Any unobtrusive method that basically holds it in place should be enough.
I was tired of talking to my wife in the car and having her say "what"? After reading the thread, I also went to Home Depot and purchased the 1/4" plexiglass. I have a role bar installed so I shaped it to fit inside the roll bar and attached it with black cable ties. I fabricated it so is sit on the floor of the rear deck and goes to the inside top of the role bar. My question is does the wind deflector need to go all the down to the floor as I have it now or can it be cut off somewhere below the headrest and still acheive the desired results? It would be nice if I could cut it off as it would provide more accessibility.
About to run to home depot to pick up the plexi glass, but first two questions:
1. Does the thickness of the plexiglass have to be 1/4"? is that the most efficient width?
2. What exactly is the "support system" made out of? bungee cord and hooks? or is it a complete part called ____?
I just read Mark story about being given a Spider for his birthday by his wife! What is your story when it comes to your Spider and your partner. Is he/she into your hobby? Does he/she encourage you to pursue your dream of making your Spider perfect. Does he/she enjoy going out for a drive etc...
Ok, so Ive had my 86 for about 2 years. I got it off of BAT. 1986 Alfa Romeo Spider Graduate
I love the car and have not had any real problems other than intermittent stalling when fuel was below half (full tank cleared issue).
Its been tucked in the garage for a few months and was started...
Finally got all the parts needed to route the oil vapor to a catch can.
Thing is someone pointed out to me that the plastic tubing I used is touching the valve cover.
Will this be an issue? Will it melt?
Plastic tubing is supposedly suited for this application.
I'm still pretty new to Alfas and this incredible community, but you all have been a fantastic help already. I'm hoping you can help me problem solve another issue with my 84 Spider.
The car runs great, but I've always known it runs rich. I took it in for an emissions test (I don't need it -...
Does anyone know where I can find a heater hose for a 1992 Spider S4. It's the hose that goes from the head to the firewall. I circled it in red. My mechanic is having trouble getting the hose - he's not an Alfa only mechanic and the local parts houses don't have the hose.
