Run plastic to play with. I'll bolt the rig onto a longer board to
try to actually break the lexan and PETG.

I don't think the lexan will break, but the PETG should if the ball
hits it hard enough. I put a lexan washer in a vise and hit it with a
hammer. It just bent!

You're never going to break the Lexan with a pinball. The thin stuff
will stop a 22 caliber bullet without shattering and some 3/8 or so will
stop a .357 or .44.

Actually - CDs are polycarbonate. If you bend one of those, it will
splinter and shatter. And lots of bullet resistant plastic is actually
acrylic. Plastic engineering is not as simple as a bunch of brand
names might indicate.-

Actually that's not entirely correct, to my understanding.
part of a CD is polycarbonate. Only one layer is
polycarbonate.

And my understanding of bullet proof materials
are they are not acrylic, but are lexan. here in
detroit nearly every bank teller is encased in
plastic! i often ask if it's bullet proof. some of
the tellers are pretty honest about it. the bank
can get a bullet proof version, but most banks
don't, instead they get an acyrlic version! it LOOKS
the same as the lexan version, and costs a lot
less, but it's not bullet proof. the tellers seem
Ok with that.
