Let's Bring Down A Wall

Let's Bring Down A Wall

Well, the add is in Spanish.

RE: Let's Bring Down A Wall

And, I’ll bet that they don’t package that machine or its instructions for operation with even an ounces of common sense or good judgement. That machine just makes it easier for a mech. contractor to destroy a structure. They already have cheap machines which can ruin a 12” beam with an 11” dia. hole. And, they can easily rent a backhoe excavator to work on entire bldgs. or whole walls. What? Me worry?

RE: Let's Bring Down A Wall

L0oking at that brick work there isn't much of any weakening done by this work. Find something else to worry about.

RE: Let's Bring Down A Wall

If I have an unreinforced exterior block wall and they take that grinder horizontally across the full face shells of the blocks at wall mid-height - I'd start worrying.

RE: Let's Bring Down A Wall

Ah come on guys, don't you have any faith in masonry?!? As long as this isn't one wythe of brick, there's plenty of capacity in the wall. They rout out electrical and plumbing chases in an autoclaved aereated concrete (AAC) walls just like this and have no problems. The AAC walls are usually 8" thick of course. So trust your brick and block walls - just don't go overboard.smile

RE: Let's Bring Down A Wall

I have a lot of faith in masonry, but JAE is right regarding a hollow CMU wall. The wall would be seriously weakened if the horizontal chase was long enough and deep enough to take out most of a mortar joint or face shell.

In the wrong hands, a tool becomes a weapon! lol

Job security?

RE: Let's Bring Down A Wall

portuguese (Brazil) not spanish. Any way it is a common practice (even here, in Italy) to do that job by hand with more wide cuttings. Usually the position of conduits is not foreseen in the design (at least in small houses or medium size buildings): electrician or plumber (central heating) will do according to their judgement.

For the lawyers

RE: Let's Bring Down A Wall

I am intrigued by a power tool that eats through brickwork with ease, however...…….

Aside from structural concerns, the end result will look like a complete hack job (similar to plumbers drilling 6" holes in joists to run plumbing through).

So if there is no concern for aesthetics, why not just attach conduit to the wall and not risk compromising the wall??

I'd be tempted to write my name in the wall bigsmile

RE: Let's Bring Down A Wall

MotorCity, those are some VERY soft brick they are cutting in to, maybe even underfired. You notice they didn't pick a very dense brick to try their demonstration on. army They would have gone through a bunch of saw blades if they had. And to bob33 and JAE points, yeah, hollow CMU is different. The AAC that is used has no voids and therefore doesn't risk anything.

RE: Let's Bring Down A Wall

That should be used to embed carbon fiber reinforcing.

The worker seems to care about his lungs, eyes and the top of his head, but not his ears.

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
