  I'm don't know what type of connector will go in the slot, but many 
have a small lip to cover minor flaws. I if indeed the job is 3 long 
slots and not 36 small slots, I would fabricate it myself with a jigsaw 
and a file. I usually scribe lines in the aluminum and put a fresh coat 
of masking tape on the bottom of my jigsaw to protect the material, then
grab the proper glasses, and lighting for good vision. I'd mount the 
aluminum securely maybe in a vise, maybe screwed to a piece of wood.
You might want to change the masking tape part way through.
  Use a variable speed jigsaw and a new blade (I like the bimetal)
and take your time and take breaks.
   If your not up to that, make a drawing and take it to a machine shop.

I bought one of these panels for a system using RJ45s
http://www.mpja.com/Cat5-Cisco-Splitter-Panel-48-Input_96-Output-2U/productinfo/16769%20TT/
I bought it for the parts when I put together a temperature monitoring 
system for 13 freezers. (A "One Wire" system)

Not sure why you'd see filed edges in this case. If you mean the
outsides of a cut panel I do this:

a. File with a coarse file, then a fine one.

b. Go over it with an electric sander and 240-grit paper or similar.

c. Go over it by hand with 600-grit paper.

d. If I want to be extra good I go over it once more with 600-grit and
chalk in it. Commercial product does not live up to that.

IME they all have a lip. Else they'd fall out the back :-)

That's exactly how I do it. I use a Bosch 230V jig saw running a bit
slow on 120V, makes nice clean cuts. You just have to resist the
temptation of rushing the job by pushing too hard.

I clamp it to a wooden workbench. Also with some masking tape so the
clamps won't mar the aluminum.

No.  Outside is easy -- you can bring power tools to bear (belt
sanders, etc.)  But, when cutting a long, thin slot/opening in the
interior of the piece, your choices quickly get limited.  Esp if
you want nice square corners, etc.

The ones I've seen are all *mounted* from the back.  See the

Well, in my teenage days I did both inside and outside strictly by hand.
The only power tool I had, and only on occasion, was dad's electric
drill. But strictly no milling or routing with that because it would
have ruined the bearings. When I was 15 or so my parents gave me a new
Metabo drill but I didn't want to wreck its bearings either. I didn't
really have any other power tools until after my EE degree except for a
huge and rather dangerous home-brew grinder.

For the insides I glued sandpaper on a piece of plywood, made the
smoothing job quite easy.

True, when they are on a PCB they do not cover the slots. But it ain't
so bad to get the slots done cleanly. A couple of years ago I did that
for an audio rack. Looked like it came that way from the manufacturer.

Back in Europe engineers had to go through part of the apprentice
program that journeymen go through. It teaches students precision filing
and all that. We were only allowed to use simple power tools such as the
drill press. And woe to him whose piece of workmanship was 0.005" off
somewhere. The master would make you start all over, from scratch.

Most of the units I've seen (I've accumulated quite a nice
collection! :> ) have the connectors *peek* through the slots
in the front metal plate, mounted from behind.

For example:
<http://www.genesistems.com/office/pics/PatchPanel.JPG>
Note the "black dots" -- each a boss/stand-off that's supporting
the PCB onto which the individual connectors are mounted.

Or:
<http://www.showmecables.com/product/Cat5e-Patch-Panel-48-Port.aspx>
which has some alternate thumbnails showing detail of the
openings in the panel -- along with a view of the back side.

E.g., a PCB (or, a set of PCB's) is mounted behind the panel.
On one side of the PCB, the connectors are mounted.  On the reverse
side, a series of punch-down blocks (the third thumbnail) which
are connected to the connectors via traces on the PCB's.

Viewed "end-on" sighting down the row of connectors, you have:

    CCCC
==========
B        B

where CCCC represents the connector's body and B the punchdown
blocks.

But, the epiphany is hidden in your phrase:  "a small lip to cover
minor flaws"!  I.e., while the connectors themselves don't have such
a lip, there's nothing to prevent me from *making* one!

Specifically, creating a "precise" veneer to mask any ugliness
in the fabrication of the "metal/lexan panel".  I.e., use the
panel for structural support and adhere a thin (rigid) plastic
veneer *to* it!

You could precisely cut the slots in that veneer with a good
straight edge and sharp xacto knife.  Heck, you could even
make it out of an exotic *wood* veneer:  "Be the first on
your block to have a Mahogany patch panel!"  :>

With the veneer approach, you could be *really* crude in how well you
cut the slots.  And, "filing" would only be necessary to remove burrs,
etc.

Yes, I like this idea!  It's something that others could easily
reproduce and get "good" results -- all while avoiding the need
to locate some "service" to do the work for you!

Oh, yes!  A rigid (thin) sheet of plastic onto which is adhered
a nice, *legended* applique (photographically reproduced from a
Photoshop/Illustrator file created on your PC for $2 at your local
Costco, etc.).  Make things look *really* professional/custom!
Much cleaner than scribbling what each connector services *on*
the panel itself!

And, for little/no money!  Finestkind!

Hey, can you elaborate on that Costco deal? I am always looking for a
fast way to make nice-looking front panels. Do they offer some sort of
thick-plastic printing?

Dunno.  I was just advocating a *regular* 8x10 glossy photo print
rubber cemented onto a plastic/aluminum panel.  That way, you can
get the "graphics" as a commodity product.

[Realistically, a glossy photo would probably not fare well.
But, that doesn't mean you can't take advantage of some other
"print from PC" technology to come up with a nice legended overlay.
I.e., separate the cosmetic from the structural requirements...]

Decades ago, we used to make those stick on "serial number/product
ID" plates on a 1-off basis in the blueprint room.  Some sort of
aluminum(?) with a black coating that could be etched away
(or, maybe it was *deposited*?).  With the sort of technology available
today (photo processes), it should be possible to do at least that
same sort of thing (IIRC, we made a template from clear film and
stick on lettering -- then "exposed" this onto the aluminum product)

In any case, something like the above solution(s) should be available
for hobbyists trying to make 1-offs without dropping a lot of money
into something with little *functional* value.

There is. More or less a spin-off of the laser transfer system used to
prepare PCBs for hobby etching. 

<http://www.pulsarprofx.com/decalpro/>

I have used their green stuff for PCB layouts (ages ago). Have not
tried making the DIY dry transfers.

This I printed on paper, and then put some stikcy transparent over it.
The rectangular hole was made with a jigsaw.
 http://panteltje.com/panteltje/pic/swr_pic/swr_box_front_1_img_0982.jpg

The LEDs are behind holes in the alu, you only see those when on.

It needs a LCD bezel and a new printout and foil glued,
but it seems to work this way too ;-)
But if you do this right it can look cool, print text in color too (inkjet),
and the transparent foil makes it shine, shine sells.
 http://panteltje.com/panteltje/pic/swr_pic/swr_box_front_2_img_0992.jpg

I messed up the foil when sliding it in, was too thick...
else it is really flat.

I have used clear label material to do something like this.  You can
get 10 8.5" x 11" sheets for $11 and just print it up in a color laser
printer.

They also made a silver set of labels that I used to make serial
number panels for.

Yeah, I was tempted to take a D size (smallest I have) sheet of
mylar, cut off the title block, etc. and try printing on that!
(thinking it might be better than this "card stock" I used)

But, I don't know how hot the phaser runs (since it melts wax)
and the only color laser that I have has a high temperature
fuser.  In neither case did I want to risk trashing a printer
just to see if mylar would make a good "medium".

[And, of course, laminating that afterwards subjects it to yet
another thermal process...]

Polyester or mylar can be used in a laser printer.
Vinyl or tyvek can not. Acetate is also a no no.

By as astounding coincidence, we have several dozen miles of clear 
polyester film in stock.

Still trying to build a rewinder to make sanely shippable eBay offers.
We are open to a bid on the entire lot. FOB Thatcher.

Hence, my using label material made for laser printers.  Fun thing is
that the front of the package say ink jet.  If you read the
instructions, it says it is for lasers as well!

DuPont says mylar is reasonably good to 200C.
paper is good to about 230C, so that's not much less.
It should work fine

What does "good" mean?  Do it's surface qualities change (e.g.,
become "tacky" and more likely to adhere to the drum?)

> paper is good to about 230C, so that's not much less.
> It should work fine

The fuser in a laser printer operates at ~200C.  (low temp toners
operate at lower temps -- but, I think those are primarily monochrome?)

 From what I've found re: the Phasers, they operate at a much lower
temperature -- 135C.  So, I think I'd feel safest trying mylar on
a Phaser instead of color laser (though I would be more distraught
it the Phaser was damaged than I would the color laser!)

<frown>  I'll have to finish my experiments with "card stock" and
see if they are good enough to warrant NOT risking the mylar
experiment.

Thx!

It's not hot when it hits the drum in a laser or LED printer, it's the
"fusion roller" that you have to worry about. Typically a halogen
light inside a hollow aluminum roller with a silicone sheath. They're
service items, so even if it and the roller heat pushes against it got
gummed up it might not be a catastrophe. Still, when I suggested it at
a copy place, they were rather unenthusiastic even when I said I'd pay
for a service call (should have just cut it to size and implied it was
a standard overhead sheet). The small color lasers don't deliver much
opacity.

Yes.  But in a *Phaser*, the drum is hot (and the *ink* is hot!)
Paper is relatively inert even at temperatures approaching its
flame point.

photocopiers will print on polycarbonate film, and presumably full-on
rigid lexan sheet stock if you've got one with a straight paper path.

If you print a mirror image and then back it with an opaque layer you
can face the clear side to the environment and protect the artwork,

Else print on ordinary paper and run it through an ordinary laminator,
almost as good (as long as you keep it dry) and less technically
demanding.
