Materials question?

I know it is possible to by "flexible plywood" or "flexible MDF" - sheet material that can be rolled up in a single direction, whilst remaining rigid in the other.

However, I have only found versions that roll with a minimum radius of about 15cm / 6".

Does anybody know of a similar material that can be rolled with a much smaller minimum radius, say only 5cm / 2"?

It doesn't have to be wood, any easily-worked sheet material will do if it can be rolled in one direction whilst remaining rigid in the other will do.

Ordinary wood veneers would do that - Ash/Beech perhaps ??

OK, additional question - I have it in my head that veneers are around 1mm thick - do straight/plain router bits come that narrow?
It looks like they do: http://www.google.com/#hl=en&sclient=psy-ab&q=1+mm+router+bit has a first hit showing 0.8 mm carbide router bits.

Cool, thanks, chaps.

Link is relevant.

Oh, it is. Unfortunately, I'm planning something much larger, maybe as large as my head.
Laser etching might be better still, especially if we use a nitrogen feed to stop it charring.

I was at the Mach show at the NEC yesterday - one exhibitor did boring bars 0.2mm in diameter.

Good point - I shall be near a laser cutter in the summer...

If it's working.

Oh...
"Boring bars"? The bars I go to are usually pretty interesting!

Peroxide will clean up the char. I used that on some laser cut R/C models.
