Making a rubber-engine submarine model

The tube is soldered to a galvanized rectangle. I’m going to drink a fighter.
Now there is a lot of grinding, we bring the shape of the hull and cabin to a streamlined one. The oil was bad.
The workpieces are rounded using a grinding nozzle and a screwdriver. Jigsaw cut blanks.
A brass tube with an inner diameter of 2 mm was suitable for the screw bushing. Soldering steel to galvanizing is difficult, but possible.
The screw itself is made of galvanized steel 0.4 mm thick. We use a grinding nozzle for a screwdriver. 1982 It seems like with the help of such a flux soldered.
The length of the boat is 40 cm, the height of the hull is 9 cm, 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.
On four elastic bands, the boat swam very briskly and even tried to sink. Without https://tonaton.ng/s_256-feminine-care-products hesitation, he spread the silver. It seemed to me too easy to make a boat out of plywood.
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 did not want to go to a dirty pond, a summer shower came up as a test site. It looks like the paint lay flat. You need a special flux for soldering steel.
Steering wheels assembled. I added some aluminum powder to the yacht varnish, mixed it well and painted the hull with a brush. From below, the rubber motor is protected by a thick copper wire, which also https://jiji.ug/removals-and-storage-services/haulage serves as a ballast. The shaft is clamped into the screwdriver chuck and the engine starts much faster. I was too lazy to look for drawings in the archive of the Modeler-Constructor. After the paint had dried, I drilled holes for installing depth rudders. Shaft – steel wire with a diameter of 1.5 mm.
The elastic band is stretched. We give a rounded shape using a grinding nozzle. My father teaches me to swim. In the house of pioneers at an exhibition of children’s art, I saw a similar model of a boat with a rubber motor. To do this, hastily made a stand for her. True, in order to start the model had to climb a ladder. Only she was made much prettier than the one that my father made me. The model was made by a seventh grader, sorry I don’t remember the last name.
Cut out the screw blank according to the sketch. In this dacha I remembered about the submarine on an elastic band, which I saw in the house of the pioneers. I then, apparently, from a great mind thought, that the guys are doing nonsense. 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. It was necessary to go out into the big water in order to finally understand how it would float. PS: The boat is ready. Weight determined by eye. Screw
The rudders are made of 0.8 mm thick galvanized steel. 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. In general, he began to cut at his leisure. We “draw” a screw on it. I tried to reach her. The first test was carried out in a water barrel.
After ship repair work, a new screw with a diameter of 9 cm was installed on the model.
With the new ballast, the boat stood up to the water remarkably. Bent in a vice.
A hole with a diameter of 1.5 mm is drilled in the center of the screw.
The sleeve is screwed under the body with two screws.
Zip with a jigsaw and the body blank is ready.
He hung a lead plate on the wire. At the dacha, a lot of scraps of 20 mm boards were lying on the coals. The shaft is inserted into https://tonaton.co.tz/s_30-power-bikes the sleeve.

1974 An elastic hook is glued into it on cyacrine.
The mass of the ballast was clearly insufficient. A spare propeller with a diameter of 9 cm was also made. Rubber motor I wind up the speed by 100-120.
The cabin is glued to the hull with epoxy, But the pond was shallow. Such a board made it possible to make the model more or less voluminous. Fine motor skills develop the brain, according to domestic scientists. A hook for an elastic band is bent with round-nose pliers. Robots need to be made, but the boats are elasticated. Of course, my father insured…
The first screw was made with a diameter of 6 cm. The boat dived and swam into the depths. Fragments of caps from plastic bottles were used as a plain bearing. The screw was soldered so that the shaft protrudes 8-10 mm from it.
The cabin of the boat is sawn and the same trimming of the board. Sometimes I remember this, I try to check this statement and start cutting out different “toys”. Masking tape is glued to the galvanization. We go to the river to swim and run.
The hull of the boat is painted, first oiled the hull,
to emphasize the texture of the wood. The boat turned out to be pretty, it’s not a shame to put it on a shelf. When the rubber band folded 4 times was installed, the screw broke off when the engine was started. And my father pushed me to get it myself. 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. I sketched the profile of the hull immediately on the trimming of the board.
A hole has been drilled in the front of the boat. I drilled holes for the M6 ​​bolts, on which the rudders will be fixed. The boat lay on its side. Present
