How to make a boat ?
buy a boat, boat or other floating means, can afford not everyone.Not everyone is satisfied with the characteristics of the proposed models the industry, and there are still craftsmen who want to do everything with their own hands.In our paper will prompt them how to make a boat of fiberglass, as well as how to build a hovercraft.
How to make a boat of fiberglass
should start with a set of housing.This work is best done in accordance with professional drawings, especially if this is your first product - then it will not have to redo it.The housing of the future boat is necessary to sheathe a thin veneer, and then tightly paste over glass fiber in several layers.It is important to use the fasteners (bolts, etc.) exclusively from stainless materials - bronze or brass.Fiberglass before use annealed using a blow torch to light brown.Without this material is poorly impregnated with epoxy or polyester resin, which then turn into the fragility of the housing.When selecting
resin should be borne in mind that although the epoxy resin is more difficult to work and - it is much stronger than polyester.When vykleyke first and several subsequent layers of skin can not do without steklorogozhi - coarse glass.On the outer layers of the body better to put satin fiberglass on top - fiberglass - a rare thin fabric, well impregnated with resin.Ready housing carefully oshkurivayut and polished.Getting this procedure before final hardening resin.The work is best done in a respirator, while actively using power tools as described processes are rather time-consuming.
How do hovercraft
Compared with a conventional boat, hovercraft does not experience significant stress, as almost all the load absorbs a flexible fence.Therefore, to build a body of such a boat is quite simple.The only thing you should pay attention to is the weight of the structure, the vessel should be very easy.It is also important to pay attention to the future aerodynamic boat, since it will depend on the already very impressive fuel consumption.
The hull can be made from fir slats, sheathing them later 4mm plywood.Plywood is normally fixed with epoxy glue, but hang a cloth is not necessary in view of increasing the weight of the product.More advanced designers create their own boats, using computer-3d technology.Unsinkable boat is achieved in several ways.You can set the side compartments are watertight partitions, even better - fill them with foam.Some are placed under the flexible enclosure inflatable cylinders.
It immediately raises a lot of questions that every designer tries to answer by yourself.What should be the engines?What will be their weight?How much and how many fans will be on their blades?At what angle to perform the angle of attack and how much it will eventually cost?Universal answer here may be due to the designer fantasies and consequently - the individual characteristics of each product.This phase of construction of a boat on an air cushion is the most expensive.
assembly of flexible fencing
This is probably the most difficult stage of construction of boats.Due to the constant contact with the surface, the flexible barrier wears out quickly, so the best material for its production - canvas fabric.Practice shows that this fabric will need no less than 14 meters.The wear resistance of the fence trying to improve, resorting to all sorts of tricks, in particular - the soaking canvas diluted in the rubber adhesive aluminum powder.It is important that the torn or worn flexible enclosure can be easily restored.
assembly housing and installing the fence is carried out on the future boat tilted up.Raskantovav body, begin the installation of the power plant.You can then supply to the engine management system and send the product to the test.Approximate dimensions of a homemade hovercraft: 3700 to 1800 mm.Depth - 600, cushion - 300 mm.With a weight of 120 kg and a fuel consumption of about 15 liters / 100 km.This ship can accelerate to a speed of 60 km / h.As you can see, making a boat with your hands is quite real!
