Lexan shatter? Unless you freeze it, it's less likely to shatter than
the
piece of oak you're cutting on the sled you built.


Really? Oak must be pretty shatter prone, because I have seen many of
peices
of Lexan or acrylic sheeting shatter. I tried to cut a peice with a CMS
once, wasn't pretty.....



It had to have been acrylic which will crack/shatter very easily.
It does have the benefit that it doesn't scratch very easily.

Lexan on the other hand will never shatter even hitting it with a
sledge hammer, but will easily scratch.

Acrylic is much brittler (is there such a word as brittler?), but I have had
lexan shatter when cutting it with a CMS. It sent some pretty impressive
shards out.
