Really? Acrylic yes, but you'd be hard pressed to get Lexan
(polycarbonate--different stuff altogether, I believe) to shatter.
Post pictures if you do. In fact, it's used to make shatter proof
features, even bulletproof in thicker construction.
Yesterday I was milling some parts of 3/8" Lexan sheet. On my metalworking
vertical mill with a regular 2 flute end mill for aluminum. What I can say
Lexan is amazing stuff. Tough, not melting, not brittle, pure pleasure to
work with. 1/4" deep 1" wide single pass cut is very smooth, shavings from
the mill are clean and don't have a slightest sign of melting. Aluminum is
much worth--it DOES melt and sticks to a mill. Regular 6061 alloy
machinability is considered fair. I would give Lexan "Excellent" grade.
Pure pleasure. It would definitely made fantastic jigs. Much better than

Try flaming the edges of the cut material with a torch.
The only drawback to lexan is that it scuffs and scratches easily. If
you are looking for a satin type of finish just steel wool it.
Other than that it is great stuff!
Save the Acrylic for display cases for which it is great for. It won't
dull after repeated cleanings.
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.
When lexan was first introduced they made frying pans out of it to
show some of it's properties.

You got frying pans, we got individual size pie plates.
Put it in a vise to try to crack it.
No luck, it bent but didn't break.
BTW, like TeamCasa, I'm a birch ply kind of guy for sled bottoms.
This coming from a top poster?
Lexan is shatter resistant, not shatter proof. I PERSONALLY had a peice of
3mm lexan fly apart in many small peices. Maybe you don't consider that
shattering, but I do. I also have had simular experiences with plexiglass,
which should not come as a suprise.
Regardless, there is no reason to be an asshole, so welcome to my killfile.
I don't have any experience with Lexan, but another poster in this thread
also experienced a peice of lexan shattering in a CMS. Possible they are
confusing Plexiglass with lexan, it's a common misperception. What is the
reason for the snarkiness?
Well, there's at least one historically (and consistently) misinformed
individual so confused, and this one was number two. All after some
very knowledgable responses to the OP indicating the difference
between polycarbonate and acrylic and how it is exceedingly unlikely
to be able to duplicate the effect on one in the other. I get testy
about them, too. Makes me want to give them their sign.
