Cutting aluminum plate on an ROS. Do-able?

I have a piece of 1/8 aluminum plate. I need to cut two strips with
very straight edges to make a hinge mortising jig.
http://www.woodsmithshop.com/download/409/hinge-mortising-jig.pdf

I've cut aluminum on the bandsaw (which I don't like doing) but I want
perfectly sized and straight edge pieces. I'm thinking that I could
get what I want if I cut it on the radial arm saw with a Freund
blade. Is that do-able or is it a whack-o idea?

-----------------------------------------
Thought for the day:

Take the tent pole down,
Put the flag away,
Monkey had a hemorrhage,
There will be no performance today.

Throw the existing 1/8 pieces in the scrap bin.

Proceed down to your neighborhood hardware store and buy a 1" x 1/4" x
36" Al bar.

Return home and cut 7-1/2" long pieces on bandsaw per spec.

(Cut 1/16" proud and clean up cut square with mill bastard file.)

Have a beer and enjoy your accomplishment.

Not picking on you, we've all been there<G>.

I have no qualms in doing so, just be sure the stock is well secured. I was
once ripping an aluminum yardstick into narrower pieces and it wound up
wrapping itself around the blade ruining a nice, slightly over 1/16"
Japanese thin kerf blade.

Hey, life just got easier. If I can get this as presized stock at Ace
or Home Depot, that takes care of that.

Thanks to all for the wake-up calls.

Personally, I just reach for a wood chisel and mallet and do it just like
I was shown many years ago.

Works well enough--I've done it on occasion. Just take your time and
wear good eye protection (goggles that seal to your face and a face
shield over them)--you're gonna have fine sharp edged chips flying
around and one of them in your eye can ruin the rest of your life.

I have cut that stuff on a table saw, a mitre saw, and a band saw...
but I wouldn't even think of doing that on a radial arm saw.

How many jigs are you planning to make?
Home Depot carries 1" x 1/4" aluminum stock.
Cut it with a hacksaw and hit up the cut ends with a file.
Save the plate for when you need plate.

Doable? Yes. But a tablesaw would be better and safer.
You did notice that the plans call for 1/4" Al bars? Your 1/8" will
probably flex too much to be really functional.

To each his own.

#1. A ROS is a random orbit sander, not a radial arm saw

#2. I've been a carpenter for over 50 years. I would never use a
contraption like that shown to cut a hinge mortise. Consider a
router bit with a top bearing. Cut a hinge template that is an
accurate fit for the hinge itself. Simple and repeatable. I own
the Rockwell set and a Bosch set. I use my simple homemade
templates unless I'm cutting 10 or more doors. No re-thinking,
matching collets and bits, calculating.

#3. Aluminum cuts just fine on anything that can cut wood. The
cuts will NOT be smooth. If you can buy bar stock, do so.

Have cut much Al on a RAS with a special non ferrous blade. Just don't
do a climbing cut. Of course all the PPE should be used.
