While you're here, how about checking out the Astronomy Book List ?

Andy,

I agree that if you use two discs of teflon that the surface deformation
issue is not so important. But since Teflon costs 10-20 times more the
HDPE, and since a single disc of HDPE is necessary to perform the same
job, it seems a waste of money to use Teflon, unless you happen to have
a sheet lying around (care to share if you do?)

here. Any mild roughness on these areas would not be enough to do this
to 3mm Teflon especially if you use two discs.
