And deep river, and a small lake, a pond and a homemade catamaran will not only fun, but also a useful tool.It is possible to sunbathe, to jump from it into the water, because it is almost impossible to turn.You can use your self-made catamaran to transport small loads, as well as to swim to explore the cages in which fish are caught.If you create a fleet of such vessels, it is possible to arrange a small competition for speed, either figure driving, they also will be an excellent tool for making small hiking.
What deal?
To assemble the catamaran with his hands, you do not need any special materials - they are all available and very easy to process.If you do not take into account the metal elements, you will need ZMM-plywood slats section 15-25 and 25 * 25 mm and a length of 3 meters.This is the main advantage of the resulting raft, as well as its feature.It is best to use waterproof plywood.If there would be such, it is better to buy a birch, but even in its absence allowed the use of spruce and aspen.
If you have seriously decided to do a catamaran with their hands, the choice of plywood is a very important step, because it will depend on the longevity of your boat.Naturally, it is important to show diligence and thoroughness in terms of finishing individual parts, as well as their compounds.Plywood should be preheated to impregnate natural linseed oil.It is better to put on a hot sunny day, using a broad brush.Heating the varnish must be made solely on the water bath using a wide dish with boiling water.Of course, it is important to remember to be careful, because the burn hot enough substance painful.You can complete the operation of impregnation after drying oil ceases to be absorbed into the wood.Typically, the application is carried out two or three times at intervals of several hours.
Components
So sorting out the issue of how to make a catamaran, should be considered in order.The pontoons raft made of slats and plywood.It should start with the frames.To do this, cut out of plywood 12 pieces having a size of 320 * 320 millimeters, knock them three or four nails, and then process all along the contour.Next, we need to make cuts under the rails.Racks are square, but the slots must be 20-25 millimeters in size.The remaining 5 millimeters in the rails are equipped with slots.It is best to put all six strips nearby, secure them, and then make a saw cuts all at once.Since the edges they will get a little deeper, it is necessary to equalize the average depth, shifting dosochki several times in the process.
Before forming grooves should check the size of plywood sheets.When it comes to the number of less than 1500 mm, it is necessary to adjust the place of installation of the frame cross member 7 and 5, respectively.Six frames require them from the sides and top rails were attached segments, and the bottom is to fix a piece of board.All you need to make the most durable, best used for this screw or screws, because in the rack will be hammered nails, whose task is to keep the plywood.
Assembly vessel
If you decide to do a catamaran with your hands, you will need to prepare some strips.The length of the four of them should be on the three-meter, two - by 1.9 meters, will also need four pieces of 570-600 millimeters, and then you can proceed to further work.It is understood that the cost to place a pair of upper rails from below, enabling the frames to sit firmly in their place.Immediately you can fasten with screws a couple of crossbars, and then lay the keel rail, then screw it to the frames 1, 5 and 6. Then you can turn the framework for the catamaran to the side to secure the top rail to the same frames.
board thickness of 50 mm you will need to cut the stern and bow of the boss, and here it is important to take into account that their form must be tapered.And then they have to be inserted in the place previously styanuv upper wire rack.On the nose and aft keel eaves rail is made from a few scraps.
Sheathing
Now it's time such an important element, as paneling.To do a catamaran with their hands, you need to cut out a few items.The width of the central portion is 823 mm, it is not difficult to cut.It is easy to bend the frame in shape, as it has already passed the procedure of impregnation varnish.But here it is important not to hurry.To facilitate the work required to pull the blank wire, ropes, or something else, and then left in this position for several days.It is worth noting that the plywood should be fastened with nails, however, you must first place the bond fluff thick oil paint on rails, frames and plywood in the appropriate places.Carefully follows promazyvat all the joints in the frames.
Continued assembly
If you do a catamaran with their hands, the drawings have to think carefully about it further on cardboard template you should determine the form of blanks for overhangs.There must have something similar to a cone.They are installed similar to the previous item.Plugs must be fitted only on the paint.They have refined the contours of the finished trim.Racks should arrive 9-11 on the paint, as well as all other details.Then you can do the cutting deck circling the contour is almost ready pontoon.When the deck is nailed, it is possible to complete the production of the pontoons.During installation of paint should not be spared.
Deck
easiest way to do it from the same plywood as the other parts.For the strength of the top and bottom rail is nailed in increments of 300-350 millimeters.If you do not trust the strength of the plywood, you can lay it in two layers, after putting on one another.Where pedals are mounted, it is required to adjust the step slats with them respectively.Of course, talking about how to make a catamaran, it is worth noting that the deck is appropriate to use other materials, for example, thin boards to be nailed so that space between the pontoons remained breadth meter.
working part
If you decide to do a catamaran with their hands, the propeller drive is made from parts of a bicycle.You will need to use a couple of frames to the nodes of the carriage and pedals.Cut the ends of the frames should flatten, and then attach the deck to the rail by means of screws.Between the pedals must be installed spacers having a length of 120-130 millimeters, and the pedals themselves to be connected by common long pins.
Water catamaran is equipped with paddle wheels, which are made of a bicycle.The blades must be cut out of rubber having a thickness of 4-6 millimeters, and then to primotat wire spokes.One wheel has to be equipped with five or six blades.
Functional area
The seat is made of plywood and slats, the cross section of which is 25 * 25 mm.Fastening the seat to the deck is carried out after it is installed propeller drive - so that the bottom rail were not available for a stretched chain.Attach best elements with screws, as may well be necessary to make the provisions of the regulation.
So you do catamaran photo you like.What follows is to make the steering, this is also required slats and plywood.Dimensions rudders - 200 * 320 millimeters.It should be right with the help of nail plywood slats bracket with sides 200 * 200 millimeters, and then let him pull the lever, which must be installed on the side, in the vicinity of the seat.Longitudinal and transverse axes of the rods may serve as thick nails for which the drill hole to be drilled, or traction may burst.
final stage
catamaran with the assembly should not be any particular difficulties.The pontoons must be installed on level ground, after which they can rely on the deck, mark the place of installation of bicycle frames with pedals, seat and drive the propeller.But do not rush to fixing all of these nodes.All the wooden parts of the raft should be painted with three coats of oil paint.Since each layer to dry needed a day or two, you will be required for this operation a week.
When the painting is complete, you must install all nodes in the field.The seat is mounted in the end.To tie the catamaran to the pier and for the convenience of carrying it is screwed on its sides 4-6 doorknobs.
