Who just happen to be 2.5 percent various metals, by weight.

Funny nobody mentioned r/EmoLocksmiths

Edit: actually it's not funny. At all.

For softer adhesives, like silicone (frequently used for installing mirrors) or two sided tape, a fishing line will work.
For automotive glass adhesive (like when you're salvaging a windshield at the junkyard) you can use a thin cable (like a hood release one) and wrap it around a screwdriver or block of wood at each end as handles.

"Mayor, there's a crew of workmen and a large amount of heavy equipment working just outside city limits."
"Why are you telling me this? Can't you see I'm working on the budget?"
"I think they may be trying to trigger an earthquake!"
"How long have they been there?"
"Couple of months now."
"Oh my god!"

Form that into a sphere and you've got frosty Jupiter.

That could be more of a divergence given we're both descended from small furry mammals.

Another analogy is convergent evolution. Wherein creatures that look similar, and occupy similar ecological niches may have come from very different forebears.

The truth is somewhere in the middle. Some of the VOCs from the copier will get trapped in the bag of charcoal. Just by virtue of it being there.

But this is absolutely not how effective filtration works. Filters are classified in terms of the media used, and the percent of a given particle size they're expected to block from the air that passes through the filter. Since we have no idea how much air is passing through the bags of charcoal (some percentage only slightly above zero) we can say that the air is effectively unfiltered.

I doubt it. The chimney is the last thing you want as a structural support for joists or rafters. If anything, you want as little wood touching it as possible because of the fire risk.

Bit by bit disassembly is the way you'll see if it's supporting anything important.

Looks like a just a widening where the metal chimneys entered. Maybe something to help with the updraft.

But I'm not sure why you're concerned about this. Is there an attic above? That's where I'd start disassembling the chimney. From the top down - brick by brick until I was at room level.

It's because they're from Toronto. Everyone from Toronto is an asshole.

Sweated drain plumbing maybe. They're harder to get right, and harder to test.

We're talking about different products I just realized.

Consumer install window film is stuck on with two sided tape to the inside of the frame. This creates a gap from the windows which are recessed from the plane of the wall surface. You put the plastic over the window trim like so.

Plastic film works the same as a glass storm window. There is an element of a physical substance separating the warmer and cooler air, but it's largely the trapped air because it conducts heat so poorly, it's an invisible heat blanket.

A plastic film acts like an extra pane in a multipane window. Even though it's just air trapped between plastic and glass (not argon) the added space acts as an additional insulation layer.

> might only be serving to hold drywall,

That's exactly what it is. A drywall backer. Framers often need to add these in inside corners where one piece of drywall would lack support.

Right. But where are we measuring that bp? I'd assume body as there's no need to have that much pressure at the brain.

So, if you measured a giraffe's BP at the head (while standing tall) would it be similar to a human's? And do they suffer a major headrush when going from ground grazing to treetops?

If the sink is installed, I'd just drill through with a ½" diamond hole saw (~$10) and continue at the end with a standard metal bit. Be sure to keep it wet and take your time for the stone part.

Weight? Heavy industrial rope, cable?

You need somewhere to be sucking the air from or you won't be getting that water out.

Conversely, most water supplies are blown out for winterization. If you can apply compressed air somewhere and blow it out the tap.

Worth noting that if that 50000hr number is correct, that's 8hrs per day for 17yr.

Note that if you have exposed joists, you can attach the climbing wall studs directly instead of bothering with stringers running crossways.

If going perpendicular to the joists, you can pick an appropriate joist, cut the studs to lean right against it.

If parallel to the joists, just run each stud up one side of the joist and screw. Then your wall will have the same spacing as the ceiling. Will use less material and be simpler and stronger.

Agreed. Anytime my kid goes in the vicinity of my grand piano, they both fall through the floor to their deaths.

Well laid arches are strong structures on their own.

It seems pretty clear the original arch was done without steel support. Obviously, most stone or brick arches throughout history were done this way. Steel support was a way provide a bit of insurance in case something failed - and possibly a crutch used by someone not doing their best work.
