Evidently the manufacturer thought about that because the ones I did

20 or so years ago show no corrosion.

See, your previous sarcastic and unpleasant answer was totally unnecessary!

[knuckle-dragger]

It's also not as strong.

[knuckle-dragger]

Brick wall, metal fan... I don't see anything wrong.

[knuckle-dragger]

Too big and not long enough.

What a load of ridiculous answers! Couple of hundred bucks, indeed! What part of the world do you come from? There's not a contractor out there who'll move off his fat butt for a job of less than $1000. You can't even get a quote for a job this small!

Further let me make it quite clear: This is alt.home.repair, not alt.line.the.pockets.of.some.wealthy.worker. Like the TV show, "This Old House" you all seem to have lost the point of the whole thing: D-I-Y. So no way am I going to employ someone to do something I can do myself. The point of the original post was to ask if anyone had seen this type of tool I thought to be useful. No?... OK...just say so or STFU!

[knuckle-dragger]

Yeah, that might be the killer for the whole idea. Certainly the 1/2 inch is too small but just pushing it manually with a dowel (no cylinder) does work so at some point above 1/2" it could be useful. BTW it's mortar not concrete. The gravel in the concrete would kill the idea immediately.

[aemeijers]

Oh, STFU yourself. I paid $300 for two drilled holes through a 12" section of poured basement wall, for my furnace guy to run ducts through to the addition here. There are specialist subs out there who do this sort of thing routinely. But go ahead and bang your head against the wall, and spend hours doing what the proper tool would do in minutes.

That makes it "sort of" round. There will be a serrated or scalloped edge to it. Varying with the bit diameter, the hole can easily be too large or too small depending on where you place the tip of the bit when you drill. Not to mention the bit must be held very straight or the hole on the opposite side will be a mess.

It is probably one of the better methods, but still has a lot of potential for problems.

Michalangelo carved "David" with a cold chisel and a mallet.

'Course he was working in marble, a medium softer than concrete (I think).

Plus, he was Italian...

I tried that method going through the "cavity" section of a block wall. Still came out with a very rough hole and way oversize. That was with a 1/2" homeowner "hammer drill". I'll never try that again. It may be possible by renting a hammer drill with both drill and chisel bits though.

OP hasn't said if his wall is solid brick, concrete block or what. He did say brick I know but unless it is a very old house it won't be soldi brick, more like a brick facade.

Yep. You're right. A 6" concrete core drill costs between $66 and $77 per day to rent. At this place:

It is more fun to watch a hole being cored in a floor, like for a floor outlet box of some kind...

Some contractors will fill a garbage can with water to catch the plug...

It used to run about $500 per hole, $300 for the hole itself and $200 for the box installed and properly firestopped...

Was cool to watch the big splash when the plug fell through the hole...

Harry, first line of my original post:

"I'm trying to put a fan into a 12-inch thick brick wall. ..."

The building is about 110 years old and when I say 12-inch thick brick wall" I mean solid brick. No cavities. I believe there are 3 layers although I could be wrong about that. Inside the outside brick wall there are furring strips and then lath and plaster. Sometimes a layer of sheetrock over them or sometimes lath and sheetrock or sometimes just sheetrock depending on how I can deal with the door and window surrounds.

Its pretty easy to do. You just chop away anything that does not look like David.

Truth is, the finish on the statue is absolutely amazing, as is the detail. It is made from Carrara marble. The marble contains many microscopic holes and it may help in sculpting.

On Sept 27 I'll be returning to Galleria Dell'Accademia . (already bought the tickets) to admire not only David but a few other works by Michelangelo. It is incredible to see close up.

[HeyBub]

I heard that as a response to the question "How do you make a sculpture of, say, a rabbit?"

I didn't know the technique would also work for David.

I learn something new every day.

[Higgs Boson]

That is exactly how Michelangelo explained what he did. He was just revealing the statue that he already saw within. Of course that was Michelangelo....

Interesting bit of Italian political trivia from Wikipedia:

""David is a masterpiece of Renaissance sculpture created between 1501 and 1504, by the Italian artist Michelangelo. It is a 5.17 metre (17 foot)[1] marble statue of a standing male nude. The statue represents the Biblical hero David, a favoured subject in the art of Florence.[2] Originally commissioned as one of a series of statues of prophets to be positioned along the roofline of the east end of Florence Cathedral, the statue was instead placed in a public square, outside the Palazzo della Signoria, the seat of civic government in Florence, where it was unveiled on 8 September 1504.

******Because of the nature of the hero that it represented, it soon came to symbolize the defense of civil liberties embodied in the Florentine Republic, an independent city-state threatened on all sides by more powerful rival states and by the hegemony of the Medici family. The eyes of David, with a warning glare, were turned towards Rome.******[3]

The statue was moved to the Accademia Gallery in Florence in 1873, and later replaced at the original location by a replica.""

Sigh! Wish I could get back to Firenze to behold the Davide again. And to Rome to see the ceiling at the Sistina, which has been cleaned since last I lived there, and is supposed to be INCREDIBLE with the gunk of centuries removed...

So many places...so little time...

We saw it about 5 years ago. It is every bit as beautiful as you may imagine.

They could have save a lot of money though, just using a few gallons of Sears ceiling paint.

I can't recall (and I'm not going to go looking for it) if anyone suggested the 'foam in a can'? What your are doing is not a 'structural' strength problem so foam should work. IIRC (been a long time) they do come with a plastic straw dthat reaches into a recess. That stuff will for sure both seal the gaps and glue the fan in.

That leads to an excellent idea: Put the friggin' fan wherever it needs to be and duct the fan's I/O to an existing outside access point.
