Chuck guard glazing material?

I want to replace the 'glazing' in a metal-framed chuck guard, as well
as the window covering the gearbox scale on my lathe.
I was thinking in terms of polycarbonate, but I know it scratches
easily and it's also expensive - I have to buy an 8' x 4' sheet for
well over £100, or pay to have it cut to size. The chuck guard will
get scratched whatever I use, but the visibilty through the gearbox
scale cover is rather more important. I could always get some
toughened glass for that, do it as a separate job. At the moment it's
non-see-through plastic.
I see RS have something called PETG Copolyester which would be more
economical if any use.
Any suggestions about this or any other suitable material?

Thanks
Tim

That well-known DIY shop for existentialists with time on their hands
(Be and Queue) sells polycarbonate sheet a lot cheaper than that (and
in smaller bits too).

Thanks Tony.
Any idea what thickness(es) they sell? I reckon I will want at least
4mm.

That may be a problem...I think the stuff I bought was thinner than
that.

How big a piece do you need?  We may have a piece of 6mm Makrolen you could
have. We use it for instrument protection, and I think we have a couple of
scratched panels that we cannot use.

That should have been 'Makrolon'.

Visit your local motorbike emporium and / or scrap
merchant and cut down a biker's windshield.

You might try this company, they appear to have good stock and will supply
small quantities.

As yet never used them myself.
