From YouTube: Spraying bricks

Description

2 purposes- binding courses, scraping off imperfections

A

Yeah spraying stuff we've got antifreeze, some blocks, don't freeze, we basically get it to pretty wet, wet consistency.

B

The reason we're doing this is two things: it activates the clay and then.

B

It activates the clay and once it once it softens that little small area on the top, and then you can take your little trial and clean off any imperfections like any little ridges or imperfections. But it takes.

A

B

Minute to soak it up.

A

Oh yeah, it's soaked up here already.

B

Yeah this stuff so good, but now you.

A

B

Take the there's a little hole at.

A

B

So now so in a minute here see how it's just being the way it comes out of the press. It's got an area.

A

Yeah sure sure we've got it right here where.

B

B

And otherwise it wouldn't do that. It just makes it clean a lot easier and it activates the clay. So you're doing two things at one time here.

A

B

So you do that and then, where there's a ridge you can kind of see where there's a difference and try to take the edge off a little bit. So it'll lay a little.

B

B

It flattens out the surface quite a bit.

A

Now, if you laid in the summer like uh if you had better blocks, you wouldn't have to do this, your blocks are typically better than this.

B

A

The reason for this quality control issue I.

B

Think the size in my I think I don't know, but I don't know the mold- is different. It presses the smaller this time of year. You just can't you got. You know well.

A

It's mostly because of the quality of the soil, we're using. We.

B

Get a lot of that yeah, it's the mix we had and it was the weather we had.

A

Right we did much better in the summer. Oh.

B

Yeah, because your moisture content's way lower.

A

Yeah I mean james pressed some pretty sweet bricks from his pictures. They look pretty good.

B

He had uh I just asked. I was just talking about that when he came up, he had a sandy loam, of course down there. They have a lot of sand in the soil. I mean there's areas, that's got a lot clay, but and.

A

We have clay clay here.

B

We got clay clay right here, yeah.

A

There's other places.

B

Like winter's got quite good sand.

A

They got sandy clay and we get a little bit of layers of sandy clay here too. There's veins with that too, and.

B

This is what that layer layer is this. Stick here, yep.

A

B

This thick here within 50 mile radius, yeah.

A

B

Just depends on where you're at.

A

B

Like at my place, there's a layer there and I actually got it up in it. It's really almost.

B

It was kind of soft until they cured man they're harder than your dickens.

A

B

So it's kind of got a drying up process. You know, anyway, that's what you do kind of.

A

B

A

16 feet to wet it at the scraper.

A

About four minutes.

A

Ergonomics documentation going into the civilization startership dvd version 0.01 right here now in the summer time, you've got.

B

A crew ready you just take these right out of the machine and put them in the wall. Yeah you wouldn't have to get less damage on the box. A lot of these goobers are from the block sticking to each other yep see when you pick them right out of the press. You don't have that.

A

All right we're ready to lay you.

B

Just wipe them down they're super clean you're, ready to go, let's see, there's the crew coming down and just kind of use your hands and wipe them off and and then what I do and then, like the side that I'm going to put down, I make sure it's clean and the ends, but the top. I don't.

A

Worry about because we're.

B

Going to take care of the top on the next layer again see.

B

So we'll put it to the inside so see. This is actually still wet.

A

A

But this part about the sprayer is very encouraging, because that means no messing with the slurry.

B

Yeah yeah well and we're doing a dim when it's I mean.

A

We thought initially that the slurry preparation would be one of the major tasks. Major economics blocks in this construction method. But it's not.

B

You know if you look there's a lot of people, that they don't even use a slurry. They just wet them like those guys in texas, yeah.

A

A lot of them just.

B

I don't I just do this right out machinist, you know, I run like you how you you know, you're in your conveyors full and double them up. I run down the wall like that I'll make like a couple hundred blocks, then I'll, take a break and take them off the conveyor right here. Put it right in the wall. My.

A

Conveyor is right here. I just take them right.

B

Off put them in the wall, take it right off the wall.

A

B

I go over and put some more stuff in and run another batch. So what that means is that's what I was working by.

A

Myself yeah so far, cb we got to put that on the trailer. That's all you got to do.

B

Mobile and then I see my conveyors, I have all those stands like you got about all that stuff, but I don't use them. I just use blocks because you need to be mobile, you know and then uh oh and then a lot of times. I I uh you'd.

A

Recommend not using the feed just put them on blocks.

B

That's what I always do you see how I do it every day, yeah, but.

A

That's because you don't have legs, I.

B

Got legs, I don't like you. Oh.

A

You don't have time to set them up and at the end of the day, you gotta unbolt.

B

Yeah I got the legs just like you. Do these.

A

Oh, I got all those didn't use them because it's just quicker to you're on welfare or something.

B

A

B

I am on welford, no, no, it's just quicker when you're in a mobile environment because you got to set up it takes time to unbolt.

A

Everything: okay, that's a good point.

B

I just I have some blocks of wood that's already made, and then you, just you just run them out on the ground. Take a few stack them up here. Put the block of wood go to the next one.

A

I believe that's wisdom from someone who's done, that for multiple tens of years and.

B

Then, like when I'm doing inside walls.

A

No amateurs here.

B

When I'm doing inside walls I'll just take and run the conversation.

A

B

Be much later I'll run a conveyor right inside the house.

A

B

And it right through a doorway or a window or something but hey, hey! You go back over.

A

All right, excellent.

B

Okay, so anyway, so you don't wanna, you don't want this to set too long, because it'll soak right back in again yep.

A

B

A

So start that, let's do it and then.

B

uh You got to kind of keep. Let me show you how to do well.

A

Let me let's yeah, show us one course on the columns. That's that's something important for the crowds to.

B

See yeah I'm running, I forgot to tell you that, so you really wanted to clean. The bottom saw the one you're going to put on the bottom. If you know which side you're going to go down, make sure the ends, because every layer you're cleaning off and then it don't matter if the goopers are on the top layer, because you're going to spread it clean it off anyway,.

A

Looks like there's some excitement going on here.

B

Man we're having a good time here. It's crazy man shaker.

A

Motor disassembly uh we're about to do a reassembly reassembly of shaker motor explorer.

B

Ergonomics, I love that that's great. I got.

A

To get back to the construction.

A

And we see here, there's frost right on these bricks still.

B

That's that's good, though, once it melts it uh it'll activate your slug again. Oh.

A

B

And melt back in okay or if we, uh if you spray stuff on it, it'll melt, it see the next layer.

A

See that that antifreeze actually.

B

Would melt that in a combined chemically and melt and melt now, if it's too cold in the morning, we have to add more. The solution has to be so. It doesn't because it'll freeze on the blocks like this morning. It was.

A

B

We see the construction.

A

Is indeed possible, then, which, if we knew that then uh three years ago, when we built our workshop, we used we used cement because we didn't know.

B

You used to mate with dirt. Well,.

A

B

That's the only thing.

A

We had that didn't freeze and we didn't think about antifreeze at that point. We weren't that experienced.

B

I'm kind of tying this in the next time we're gonna have to. We will lap this and actually tie the wall back into it. One run or the other like uh this one will cut.

A

B

We have to cut a box, no, we try to keep away from the block, but yeah.

A

We just lay block across right, yeah.

B

The way they're laying out in the wall, you want a little bit skinnier blocks for you on a dutch bond, because then you got plenty of room. If you get two of these boxes, six and an eighth.

A

B

It's too wide for the wall.

A

B

So we got it, but on the columns you want to get as wide as possible, because you're you'll have narrow spots in it, but I mean it doesn't hurt anything other than uh aesthetically and then it looked just fine when we actually come back through and put all the stuff in it yep.

B

You know the divot holes and stuff and.

A

You're, basically checking the each block for quality, which side.

B

Yeah, even for.

A

B

Yeah I try to put the there's one side: that's pressed harder than the other, because it's a.
