I did a basic how-to article for the most recent issue of Make
magazine on "How to Make Square Holes in Aluminum Sheet Metal"
They have it up for free on their website, might be of interest to
And yes, there are certainly a lot more ways to make square holes than
shown! They trimmed the web article down to about 5 methods for the
print version, so I doubt I could have put even more methods in...
The hand nibbler in that article really sucks. MMC sells it for $21.00.
Don't even think of buying one. Radio Shack (of all places) in the US
(along with many others) sells a far more refined product at half the
price shown in the shot below;
Funny, the hand nibbler I've had for over 35 years looks just like the
one you just panned, and it's always done ok by me.
Maybe they made 'em a lot better back then.
I couldn't resist touring through your photo galleries, you sure do take
Could you please tell me what breed of cat "Plato" is? I ask because
about three years ago an engineer neighbor of mine working at GE's jet
engine division had to go down to San Paulo to integrate one of their
engines into a new commuter plane being built there. He took his wife
and kids with him and asked if we would board their cat for the three
months he expected to be there.
One thing led to another, and they never returned here from Brazil, so
the cat became ours. I've never bothered to find out what breed he is,
but he looks just like Plato. Here's a photo of him. He is facinated to
have been born into an era of industry and uses mechanical assistance to
help him catch mice.
He can still bring home the bunnies by himself though. SWMBO hit "high
C" last year when she opened the door for him and he trotted in and
dropped this one on her feet:
Well, okay wasn't good enough for me, especially since much better was
half the price. Seriously, MMC should stop selling that POS.
Thanks, photography is another hobby of mine.
I haven't the faintest idea, always thought of him as being just a
fluffy tabby. Have to ask my daughter, it's her cat.

I like this one too. Because it doesen't have the U-shaped hold-down on the
top of the cutter bar, you can use a smaller pilot hole to start nibbling.
Also, the 35+ year old design leaves a signature that shouts "A NIBBLER
WUZ HERE" even after filing and sanding/brushing. With the new ones,
even on aluminum, there are no leftover telltale scrapes and deep
abrasions on either side of the work piece to worry about. It's as
though a sharp punch or minature shear press was used.
Not really, that's part of why I remove it on the nibbler used for
trimming a rough opening to the finish line. The nibbler with the
U-shaped stripper plate left on cuts out the rough opening because the
modified one jams in a slot.
