He hung a lead plate on the wire. Masking tape is glued to the galvanization. 1982 I experimented a little with the pitch of the propeller, bent the blades at different angles, started the engine and watched the boat row the propeller in the barrel.
The rudders are made of 0.8 mm thick galvanized steel. At the dacha, a lot of scraps of 20 mm boards were lying on the coals. The shaft is clamped into the screwdriver chuck and the engine starts much faster. The steering wheel is fixed on the M6 bolt with a 60 mm long nut, two nuts in the center fix the steering wheels on the body.
After ship repair work, a new screw with a diameter of 9 cm was installed on the model.
The elastic band is stretched. To do this, hastily made a stand for her. You need a special flux for soldering steel. Such a board made it possible to make the model more or less voluminous. The oil was bad. The first test was carried out in a water barrel. The screw was soldered so that the shaft protrudes 8-10 mm from it. From below, the rubber motor is protected by a thick copper wire, which also serves as a ballast. Jigsaw cut blanks. In general, he began to cut at his leisure.
A hole with a diameter of 1.5 mm is drilled in the center of the screw. A spare propeller with a diameter of 9 cm was also made. But the pond was shallow.
The first screw was made with a diameter of 6 cm.
Making a rubber-engine submarine model
1974 The model was made by a seventh grader, sorry I don’t remember the last name. An elastic hook is glued into it on cyacrine. My father teaches me to swim. I sketched the profile of the hull immediately on the trimming of the board. It was necessary to go out into the big water https://jiji.com.gh/cars/toyota-auris-2008 in order to finally understand how it would float. A hook for an elastic band is bent with round-nose pliers.
I did not want to go to a dirty pond, a summer shower came up as a test site.
A hole has been drilled in the front of the boat. I tried to reach her.
Now there is a lot of grinding, we bring the shape of the hull and cabin to a streamlined one. Fine motor skills develop the brain, according to domestic scientists. Only she was made much prettier than the one that my father made me. I added some aluminum powder to the yacht varnish, mixed it well and painted the hull with a brush. According to the drawings from the magazine "Modeler-Constructor", he makes a model of a submarine with a rubber-motor engine out of 5 mm plywood.
The hull of the boat is painted, first oiled the hull,
to emphasize the texture of the wood.
The first tests on the pond showed that the pond is dirty and on an elastic band 3 mm thick, folded into two, the boat swims no more than 4 meters and refuses to dive. I then, apparently, from a great mind thought, that the guys are doing nonsense. Present Fragments of caps from plastic bottles were used as a plain bearing. Sometimes I remember this, I try to check this statement and start cutting out different “toys”. Shaft – steel wire with a diameter of 1.5 mm. We go to the river to swim and run.
The workpieces are rounded using a grinding nozzle and a screwdriver.
A brass tube with an inner diameter of 2 mm was suitable for the screw bushing. The mass of the ballast was clearly insufficient.
On four elastic bands, the boat swam very briskly and even tried to sink. In this dacha I remembered about the submarine on an elastic band, which I saw in the house of the pioneers. PS: The boat is ready. Robots need to be made, but the boats are elasticated. We give a rounded shape using a grinding nozzle.
Zip with a jigsaw and the body blank is ready. And my father pushed me to get it myself. First, we remove all excess with a large sandpaper with a P40 grain, then we grind the surface with a sandpaper with a P80 grain. The boat turned out to be pretty, it’s not a shame to put it on a shelf. I drilled holes for the M6 bolts, on which the rudders will be fixed. Soldering steel to galvanizing is difficult, but possible. Bent in a vice.
The length of the boat is 40 cm, the height of the hull is 9 cm, I was too lazy to look for drawings in the archive of the Modeler-Constructor. Rubber motor I wind up the speed by 100-120.
The sleeve is screwed under the body with two screws.
The cabin is glued to the hull with epoxy, We use a grinding nozzle for a screwdriver. True, in order to start the model had to climb a ladder. It seemed to me too easy to make a boat out of plywood. We “draw” a screw on it. Weight determined by eye. Screw I’m going to drink a fighter.
Cut out the screw blank according to the sketch. After the paint had dried, I drilled holes for installing depth rudders. It seems like with the help of such a flux soldered.
The cabin of the boat is sawn and the same trimming of the board. The boat dived and swam into the depths. In the house of pioneers at an exhibition of children’s art, I saw a similar model of a boat with a rubber motor. When the rubber band folded 4 times was installed, the screw broke off when the engine was started. The boat lay on its side.
The screw itself is made of galvanized steel 0.4 mm thick. Without hesitation, he spread the silver.
With the new ballast, the boat stood up to the water remarkably. The shaft is inserted into the sleeve.
Steering wheels assembled.
The tube is soldered to a galvanized rectangle. It looks like the paint lay flat. Of course, my father insured…
