Next picture. You see the boom coming from the truck that I developed to assemble them. And the boom is above the house. We've got the mast up. The mast consisted of seven stainless steel 22-foot long by three inch tubes each tube weighing 10 pounds. Very light in your hand. You put it up like a billiard cue on the little button there, and then seven of them are strapped together, and we had runners between them so that they would not twist like a rope, and then as you put these straps on like that, there were cleats, so you kept climbing the mast as you went on up doing it. The hardware was very exciting with this job. So that the mast, a total of 70 pound mast, and incredible carrying capacity. So there it is standing up, it is a very beautiful thing, and had a header on it, very much the kind of thing they get into racing sailing boats today, but it had all kinds of shivs ball bearing shivs and so forth, because I then had, we then had a ring that was going to be put around the mast. You're going to lift it like an elevator, and from this ring you had the, what you call the rods they were the aircraft chrome molly rods going out to what you call the "A" ring. And the "A" ring was just all screwed together kind of like a fishing pole and then, then there were diagonals going down to the "B" ring, and sort of like a Japanese lantern form as it came down like this, and then finally to the "C" ring. Then we went down, rods crisscrossed down to the floor ring.

Now, what you're seeing there is a mast standing up, and up on this heading there were all these ball bearings and you had lovely shivs, and a little winch over here so the cables would pull there were six cables came down over ball-bearing shivs through the ring, so this whole thing went up like a theater curtain. It just was a lovely thing.

And, next picture now. Incidentally, the bottom ring is in place and that is made out of magnesium was very light large magnesium castings of what we call a "Z" section, went like that, like that, that way. And the inner lip then carried the inner flow, then everything rested on that it was very, very stiff going like that, and obviously could nest. The "Z" could nest on the nest. The individual pieces were 12 feet long. The castings were about a half inch thick. It was a very powerful ring, but magnesium weighing relatively little.

When I hung, when this thing goes on up with the, then, that ring was hanging there, an amazing thing happened because you take a diameter of 36 feet, so , and you've got then about 110 feet long, this thing. Now a beam 110 feet long like that, I would just kick this thing, and like rubber it went around there, I never saw anything like it! Any one piece, you would swear nothing could ever budge that thing, I'm talking about metal this thick. And this section was 4", 12", 6" very stiff, a half inch thick. But to see what really happens then when you get to a big size, to see, you just hit it and a wave going around. It is an extraordinary thing. Of course, we stabilized that with as you do with your wire wheel in due course, but I want you to realize the very interesting experience you have as you get into things like that, you never could dream of happening.

Now, we are about then to, the "A" ring has been put in place, and the "B" ring has been put in place. Those are also lovely, those are stainless steel tubes, very, very thin weighed fantastically little.

Next picture. Now they have been raised and the roof sheets have been put into place. Now the roof sheets, I had ribs, and these ribs are what they call a hat section. This is of sheet metal, and it was only 032 they called it, it's the thinnest like they make the thin skins of an airplane with. The hat section, "U", like that, and so there is a lovely channel on either side of the "U", it is a very, very stiff affair. Then they have what they call a stretch press, in the aircraft game, so I took these straight channels these straight hat sections which were very, very strong. Each one of those weighed just two pounds. They were 13 feet long, and I the stretch press we had is a wooden form, and it has the hollowing out of the shape of the hat section, and then has the sides of the wood, are the sides of those "U" channels on the sides of the hat section. This, there are two great fists that take a hold of the ends of that hat section, and these two fists, the hydraulic arms move, and it pulls it down over that wood, it pulled it in the exact shape of your curvature. Incredible the stress press. Lovely tools you find like that in the aircraft industry. We have some lovely pictures of that, but I am really getting to a point where I can't bring all of the pictures in, I'd never get through. But at any rate, those hat sections have been put up there between the "A" and the "C" ring, and then we have, they are bolted at the top and they are bolted at the bottom.

Then, the, what we have then is the roof sheets are then just straight panels of aluminum cut triangularly so you gain economy because you can cut one triangle this way and one that way they are long gores and they have a turn up angle at their head and at the bottom so that they are pulled very tightly by bolts over the frames. If you look at them you see actually they are pulled this way. There is also a little secondary curvature, you get into hyperbolic almost hyperbolic saddles, and they don't have to touch each other, because between the two I kept a deliberate space so that ice could melt between them and so forth. There is a deliberate space of about l/8th of an inch between the edge of each sheet because each one of them is being stretched over this hat section which is a gutter, so any water just goes through the gutter and comes down at the bottom. And we, then, all the guttering we had also on the inside, an inner skin so all the moistures of the building precipitate inside, all the water outside, all came down to a built-in gutter that ran around just above the window section there. And that came down through pipes in the window section to an enormous gutter at the bottom all gutters that landed on this building, either generated inside or outside, we caught it all, it all went to a cistern.

Next picture. You'll see the whole roof suddenly. I told you that a little elevator went to work, so it was like an absolute beautiful theater, she went up like that, poof! And then, now all the cables are pulled taut across pairs of diamonds, and then we get in the Plexiglas windows and so forth.

Next pictures. And then, there is the big ventilator 18 feet in diameter, it was mounted, I used a Cadillac front wheel spindle bearing which had very good bearings, and so very good forging, as the main spindle for it to sit on. And then we had where it went around the 18 foot track we had ball bearing rubber wheels that went around a track. All of this was mounted on a splining a spline would slide this way like that, so my shaft for my top ventilator which rotated like that, could slide upwardly on a shaft. It was designed so when we get tornadoes, one of the things that happens is immediate and incredible dropping down of the pressure, atmospheric pressure incredible drop. And what happens, the buildings have air inside it, normal pressure, but suddenly the pressure drops outside, so the building explodes. That's why you see so much lumber and everything in the sky. Everything explodes.

So I had this, on top of my building now, it's designed so if there is any big explosion or there is a would be a tornado this is like the safety valve on a steam boiler, the whole thing just slides up, so immediately it was good fun, I found I could then control the elevating of that from the living room, we could even let more air in, it was all screened so that it was beautiful for regulating both pulling the airs over preferred circuits and taking care of the ventilation of the building with the aeronautical flows under complete control.

Now, you see the big ventilator being lifted on top.
