Modern Top Fuel Roll Cage Helmet Shield?

[jlucky]

Just wondering if any of you builders have any thoughts on how best to duplicate the modern Top Fuel Roll Cage Helmet back shield?

Find a very thin material that you can easily shape to fit inside the roll bar. I don't know if a thin plastic would be shapeable enough without heat to make it fit. Maybe a small piece of a paper product of some sort and paint to match the roll bar color? 

[SpeedAndViolence]

I would suggest starting with Tamiya tape to get a rough pattern of the inside, then grab a cheap tinfoil cake pan. I have never tried it myself, but I do agree with @espo, even the thinnest sheet plastic available currently, will not be flexible enough.

What about looking at preformed plastic from things like a drink bottle or preformed plastic from packaging?

Hey guys thanks for the tips. iBorg...yes I've been looking at all kinds of packaged products to find a similar shape...haven't found one yet. I do like the idea of using some kind of tin foil! That's at least a shapeable material. Thanks again...we'll see how it goes.

When you figure out what works please share with everyone what you did. It is amazing how much we learn from one another here.

Know anybody with a vacuum former?  Or just smash form a sheet of thermo plastic over a wooden buck.

The wood buck and thermoforming is a good idea. Also, in aluminum,  pick up some Maid-O-Metal tooling aluminum. It forms, easily. It's softer than regular aluminum foil or cake pans.

Cut a bit of the bubble bit on the bottom of a 2 litre soda bottle. Not sure what quantity that is in USA but they are 2ltr here in NZ

Or the foil skirt from a wine bottle screw cap is quite a soft ally and can be burnished to suit. Place it on a backing of say polystyrene and burnish the shape with your finger. You could use an ally tray but these are a little harder and may need something a but firmer than your pinky. Being ally all they need is a polish up to look the part
