My first question is what material to use? Acrylic? Lexan?

*Thick* Lexan -- not Plexiglass, because that is too brittle.
If you have something heavier than a chip (e.g. a broken HSS or
carbide mill half), you want something more likely to keep it
away from you.

1/4 inch?

1/4" or perhaps 5/16" for the size of mill you are using. For
some machines, you would want something 1" thick or so -- like
what is used to bulletproof the tellers at some banks. :-)

With thicker plastic, it probably would make sense to add a thin
easily-replaceable layer on the inside, using eg 1/16" acrylic,
which is available inexpensively at many local hardware stores.
