Anyone had any experience of the stuff ? I have a need to make three small
mirrors - about credit card size - and two of them are not square. 3mm
acrylic mirror material is available dirt cheap on Fleabay, and is reckoned
to be at least as good as glass. Question is, how do you cut the stuff
reasonably neatly ? I've cut other acrylics before and always found them to
be a nightmare at clogging any cutting tools. I was thinking maybe something
like a Dremel with a general purpose cutting wheel ? They market this
material as 'shatterproof', so that's good when it comes to cutting it,
right ... ? I wonder if that also means that it would score and snap ?

Needs something sharp - I once cut 8' along a sheet of polypropylene with a
bluntish jigsaw and found that I still had a single sheet but with a ridge
along each side!
A wheel would do it if the teeth are really sharp. Could be interesting
holding a small pieces without scratching them.

Main problem in use is that the surface is soft and scratches easily so
you will forever be repolishing it.

To cut it clamp between two pieces of wood faced with paper to support
it and make the cutting strokes slow and towards the silvered face. If
you work it hard the material will melt and clog the saw. It melts very
easily.

I bought some the other week to use as a reflector to replace the
corroded piece of metal in my car's number plate illuminaire.

As said, scratches quite easily. Gives a reflection very nearly as good
as glass.

I had to cut a couple of small rectangles so clamped it to a piece of
wood and fed it through my lathe, set up as a table saw. It uses a 2"
dia cutting saw and was probably running at 800rpm (top speed!) It
produced a really nice finish. I mention this as whenever I've tried
similar material with my Dremelesque it ends up running at a far higher
speed and melts the swarf into the piece which is then a pain to get rid of.

So I reckon way to do it (for odd shapes) is to clamp the stuff down
with a guide piece and use a fine bladed hacksaw.

Sounds to me as if you need a fretsaw. They aren't expensive.

I have a fretsaw. Actually, two, one being manual and the other electric.
Now I come to think of it, actually THREE ! I'm a bit skeptical that they
wouldn't do the old melting trick of swarf in the cut, but still worth a
try. Thanks for your input.

Use the hand saw with a plastic or wood cutting blade, cut slowly and
keep feeling the blade. If it is getting too warm, stop for a while. As
already suggested, clamping the plastic between two thin pieces of wood
will help with such thin plastic.

Just realised the way I wrote that is ambiguous. You have to work so
that on the cut stroke you are pressing the mirror against the plastic
the other way around or an aggressive back stroke and the silver will be
rip off the surface around the edges. It is surprisingly easy to melt
the stuff and smell the monomer even with careful slow working.

If the swarf comes off in large melted together clumps you are too fast.

Last thing you want when cutting acrylic is something which generates heat
as it melts easily. A fine tooth hand wood saw is fine. Finish with a
metal file. You can polish the edge with fine sandpaper followed by metal
polish like brasso.

Where I work we use a laser cutter for 5mm or less, it's very good, but also expensive so not much use to you unless you're likely to want to cut a lot of stuff with it, it's good for plywood and MDF too. We even use it for engraving on wood and acylic.

It's exactly what you want - a laser cutter. It's controling where the
heat goes that is key :-)

Yes they scratch, so be careful with the cleaning. You can polish out small

It's a bit 'static-y' I think, Brian. Not a problem in this application
though. If it does get cleaned, it will likely be rarely, and light surface
scratching would not affect its performance as a mirror to any degree that
would be noticeable in use.
