Thread: Car Weight/Windshield

This pic shows the quarter windows.

These are the prototypes and were made from 1/8" Lexan.
Since they were mounted in the middle, right on the angled piece with oak bow, they didn't work out well.
The thinness of the Lexan allowed them to set up an aerodynamic buzz.

Changing to 3/16" thick Lexan cured that problem.

The quarter windows come out in the warmer weather.

Incidentally, I've found that a cowl vent is a necessity with these small cars.
It makes a big difference in hot weather comfort.

Only bad thing about the 32 is it's louvered hood top that dumps air right down the cowl vent when running city speeds.

At highway speeds, air flow patterns over the car change and hood top hot air is depressed to a great extent so the cowl vent does a good job there.

For that reason, my new project - 31 roadster on 32 frame rails - doesn't have hood top louvers, but it will have a cowl vent once I find the right donor car.
