Cutting Plexiglass (Perspex)

[Dave M]

Anyone have experience in accurately cutting 1/8" thick acrylic Plexiglas
(Perspex) for LED displays?

I need to make filters for some panel meters of my own design, but am having
trouble finding off-the-shelf bezels and filters of the sizes I need.
Before everyone tells me that there are cheap Chinese panel meters available
on the web, I already know about them. My meters are for a unique
application and the available digital panel meters can't be modified to fill
my needs. The display is the really unique part, and I need to make my own
filters for the displays. I need 3 different sizes; 1.25" x 2.5". 2.75" x 5"
and 4" x 5".

I've thought about using a table saw with a cabinet-grade finishing blade.
That's possible, but somewhat dangerous due to the small size of the
filters.
Also thought about hot wire cutting. That's quite possible, relatively safe
(just have to keep fingers off the hot wire). Might be hard to keep the wire
taut enough to make straight cuts, and guiding the plastic through the wire
or the wire through the plastic.
Also thought about cutting on a drill press or milling machine. Again, a
bit dangerous due to the small size of the work. Clamping would be tricky.

Any suggestions as to a good, safe approach to cutting the plastic?

Stack them in a vise and mill.

"For thicker sheets of plexiglass, cut with a power saw—be it a
circular saw, saber saw, or table saw. (To cut anything but a straight
line, opt for a jigsaw.) No matter which type of saw you choose for
the task, it’s critically important to use the right blade. There are
special blades designed expressly for acrylic, but any metal-cutting
blade with carbide tips can do the trick. Before committing to one
blade or another, double-check that its teeth are evenly spaced, with
no rake, and of uniform height and shape."

For the size you're talking about, I'd think that a table-type
sabresaw or jigsaw (with a fence) would be what you'd want.

For a fancier approach - the MightyOhm geiger counter kit can be
purchased with a two-piece acrylic case, the upper sheet of which has
some custom cut-outs made for the tube and the batteries. Their web
page says that it's "laser cut". Maker shops may have suitable
laser-cutters for their members to use, and there are service
companies which will laser-cut-to-size in your choise of acrylic
types.

I've contacted four Ebay sellers of Plexiglas panels, asking if they can cut
to my dimensions. Although they all advertise that they can cut to custom
sizes, all but one of them say that they can't cut that small due to
"liability insurance restrictions", whatever that might be. The other
quoted an unbelievably high price for a small order of 25 pieces. That's
why I'm looking to do it myself.

I looked at the Geiger Counter kit and didn't see any reference to any
plexiglas except for a clear panel covering the front of the unit, clearly
not what I'm after. At any rate, I'm not going to buy several $100 Geiger
Counter kits for which I have no use just to get $15 worth of plastic.

Yes, the finishing blade that I mentioned is a zero-rake blade, so that't
not a problem. Just concerned about my fingers when they get close to the
blade spinning at 3200 RPM.
I'm leaning toward building a hot wire cutter into a frame that will keep
the wire taut enough to make a straight cut through the plastic. Maybe
mount it alongside the fence on my tablesaw. That should keep everything
nice & straight.

Thanks,

Don't know about a makerspace. Never heard of them. Have to see what

That should be no problem on a table saw. Make sure to use a zero
clearance insert. Cut into the short-side sized strips with a fence
than chop those up with a miter gauge with a stop. Perfectly safe.

Also thought about hot wire cutting. That's quite possible, relatively safe
(just have to keep fingers off the hot wire). Might be hard to keep the wire

Your first thought should work just fine as long as you take
reasonable care.

For the size you're talking about, I'd think that a table-type

I would rule out any type of saw for a few reasons
1. Such a small piece is impossible to hold effectively unless you're using a low speed handsaw, which is very ill suited to acrylic
2. Power saw speed plus very slow feed are required, and there's no way you'll get good enough control with such a fiddly unsupported piece
3. Anything else will crack it
4. Your fingers will be at too much risk

Hot wire would do it, and gravity tends to keep it cutting straight. You can sand the edges afterwards to get dimension precise. An easier option is to use an abrasive stone in a dremel, cutting/melting as close as you can to your scribed line, but never over it, then sand it.

Polycarb is a bit easier to cut. Acrylic melts and gums up blades
easier.

I have scored and snapped Plexiglas. You would need to mount it
firmly so that the corners don't break. A small fixture (plywood) to
sandwich the piece should work fine.

I've had a lot of trouble cutting acrylic on a table saw, or drilling.
The problem has been chipping on the back side. I haven't tried backing
it with a piece of wood - that should help.

What does work very well for giving a nice edge is a router. Not very
convenient for cutting into pieces, but nice for cutting shapes to a
template, or for finishing edges that have been cut with too much chipping.

at my job, we cut plexiglass( USA) on a sheet metal shear. makes a nice cut that requires little sanding to make smooth. 1/8 is thin. any tin shop would have shear that could cut that, even a manual one would work.

Make and use a small parts sled to hold the pieces and keep your fingers out of

harms way. Do a search for "woodworking small parts sled" for an assortment
of photos and plans. Use the tablesaw to just score the plastic. Don't cut all the
way through. Snap on the score lines and file off any rough edges. A propane torch
will polish the edges to a glass like finish. Practice on a scrap first as it's easy to
burn the edge.

When a hardware store cuts plexiglass for a storm door or window, they
put the sheet in a glass cutting frame. That is nothing more than a rack
with a straight edge and a lever to apply pressure against the part you
want cut. Then they use a special cutter made for plexiglass, which is
really just a sharp blade. They score it with that cutter from top to
bottom. Then they use that lever to apply pressure and SNAP, they make a
nice clean cut.

I was in a place where I had to cut some myself. I did not have that
special cutter or a rack. I marked it with a sharpie. Then I took a
straight piece of aluminum, laid it on my mark, and scored it with a
utility knife with a new blade. Once it was scored, I placed the scored
line along the edge of a board and applied pressure with my hand. That
worked fine.

One thing I learned, never try to drill plexiglass. You will end up with
small cracks around the hole. I once wanted to put some hinges onto
plexiglass and learned the hard way about the cracks. Then I used a
soldering iron and melted holes. It was kind of messy, sicne the melted
plastic builds up around the hole and needs to be quickly removed while
it's still hot and soft, but that did work in the end. (The soldering
iron tip was pretty much trash though, I ssaved it for future plexiglass
holes, but would never try to solder with it).

I would use , don't know what they're called, miniture tenon saw from a
craft shop for marketry I believe, blade only about 1 x 2 inches, but
large handle, and teeth about the same as a hack-saw size and spacing

Have a look at laser cutting. Bonus: you can cut complex
shapes as easily as simple shapes. Caution: not all
materials can be cut like that.

Look for a local Hackspace or Makerspace, if you want to
learn how to use laser cutters yourself.

Alternatively there are many commercial companies available.
Usually you just send them the CAD file and they return the
items by post, but obviously you could pick them up from a
local company.

Does it have to be perspex? 1/8" polycarbonate (Lexan) cuts with tinsnips,
no cracks, nice enough edge if you are covering it with any frame;
otherwise pass them a few times over a big file held in the vise.

 

[pfjw@aol.com]

Stuff that thin can be scored with a matt knife and broken on the score. With care, even on a curved score. For curved shapes, make a template in thick cardboard and cut along that. If you need to do this more than once, soak the curved edge in a very thin cyanoacrylate glue, then file it to the final shape. That will resist scoring by the blade.

Today, I have a Dremel Scroll-saw with a fine plastic-blade. Makes life easy. I tend to cut a bit proud of the final shape and use a very fine sanding disc to finish. It gives a nice edge and no flash.
