 Well, the walls went up pretty quick. I just came every morning and did one of the sections It was sunny all morning This week though. Oh, so hot. Whatever though. I got it done All right, then I put on these strings This is paracord and then this is just some quarter-inch rope And I put some nice fat ropes at the bottom and then another strong one up at the top Because you know, there's more water pressure at the bottom obviously and then at the top I need a fat one to support the roof Because the roof is just going to be a shallow dome Or maybe kind of set shallow cylinder dome-ish so it'll push out so I need a good strong rope at the top Now to do the roof. I was looking around and I have this Really short cone Fiberglass cone. It's like it's almost wide enough to do the whole thing and I was thinking of putting the fiberglass cone in here and then just putting Concrete over it and then pulling the fiberglass cone out and since the fiberglass cone is flexible As long as I leave a hole, I should be able to roll it up and pull it out The problem is it doesn't go all the way to the edge So I started putting the lip here So the cone will go from here up and down and touch that other side So to do this lip, I was not sure how well this was going to work It looks like it is doing the trick. It's actually working really well. I was thinking This technique could be scaled up One kid if you had the a really good curved piece You could just keep going right till you get to the center. I don't need to do that here I just need to go around the outside but I'm thinking maybe in a future building I'll do a technique like this and just do section and then like get one row down all the way around and then just move it up and do the Next row all the way around. It's pretty easy to do and this is a really shallow curve And it's still holding up This is maybe 12 hour old concrete. I did it yesterday evening And it's already strong enough to keep it shape This is the piece of wood I was using on my fiberglass form, you know to keep the shape since I'm done the walls I pulled it off Okay, I pulled it off and then made a bunch of slits down the bottom end And then screwed it down to this curve So Now it's got the curve going the right way. So when I put it up, it makes these marvelous And for my concrete release my mold release. I'm just smearing some clay on here Which does not work that well, but it's all right. Well, I know this actually makes a stick more Does not fit here well It's a nice big space there so when I made this thing I wasn't sure of the size of the concrete floor I made down here. I don't remember exactly So I guessed a little bit and when I got over here I had to fudge this and make it a tighter corner to not go off the edge We're not get too close to the edge The rest of it this fits pretty well. It's just this one spot here Now, what do I do about this? Yeah, I think I can just take some rocks and lay them in here Yeah, it'll be fine Yeah, totally good Let's put the concrete right over that Yeah, this will be fine All right, more rocks. That's pretty good Does not pass inspection Really? I don't know. Well, let me inspect it. Hmm Yeah, looks good. Inspection passed. I Just need to be careful when I put the concrete on here so I don't move the rocks Camera malfunction. All right, I'm not sure if the last video clip made it in there It was just me putting this stuff on. I just put it on by hand So it's not too disturbed my rocks I gotta go wash my hands before this starts eating through my skin Okay, now the question is why can I make something that overhangs so much when it's just concrete? There's no reinforcement in it or anything. It's just overhanging like I don't know like 20 centimeters Okay, the secret is Not that it's really big secret for anyone who understands math When I put this mold in here That means I've got one line going across here So there's no part that's just hanging straight over because this end part now this goes in a little bit So maybe this little tiny edge here is at risk of falling off But only like a little tiny bit, but for the most part this has a full line going across like a line That's in an arc and As long as the ends Hold it from pushing out. That's why I've got this nice drawing rope here It'll hold it shape so I Get like with the first piece of this which was over here it cut off over there and Yeah, it was overhanging a lot. However, it had this arc at the edge That kept it from collapsing in And then of course once the whole thing is in like to collapse in it would have to push out So as long as the outside is contained. It won't be able to push out Ah egg shells are so great. I love domes Now wants to Get everything wet and then put it all in the shade Well, all I'm here. I might as well get my little spigot not spigot the in the intake Whatever you call it the intake overflow in there My out's down there somewhere And I would kind of be really nice to get this all spackled cover up these ropes Alright No better time than the right now use my little sister over there Get all the rocks out so basically down to sand and I've mixed Like four parts sand and one part cement There's my bucket of cement to keep it covered so no water gets in it And that's gonna be my spackle I'm gonna make it pretty wet because The wall is gonna suck up some moisture right away Definitely soupier Concrete let me hope that I'm not just being crazy That looks pretty good. Oh a very elegant technique. Yeah, shut up. It's getting on there. Cheers I'm gonna leave this And go around and do the back end of this because that is gonna be the worst part Let's get it over with Oh that's looking good Just have a little bit left, but I'm out of water You know, this is not that hard to make And it would be an awesome kids clubhouse Oh, I might have to do that and make the ceiling tall enough for me to get in too because you know, I'm a kid
