We offer the modelers designed by athletes from the Czech Republic. It is simple in design, does not require scarce materials to build, has the original technology of housing and very good on-the-go. The manufacture of this mini-yacht will not present difficult even for inexperienced athletes. Those who have already accumulated some experience in composing the frames of the hull with the subsequent sheathing plywood, can reproduce the design in accordance with their habits. Before starting work you must perform a projection of the body in natural size on thick paper and cut them out. The obtained templates are used when marking pieces of foam thickness of 38-40 mm, which are then cut with a seam allowance of about 1 mm. In the plate of the foam forming the upper part of the body, perform the opening of the cockpit, which will be subsequently pasted the details of the cabins. Both the foam parts are joined with glue such as casein or PVA. After drying the binder, the billet is processed on the side view.
Basically the foam is cut using thermolabile, although in a pinch you can use a leaf from a hacksaw on metal. The hull lines of the type “Sharpie” in the processing are controlled by the templates of cardboard or thin plywood, and not enough of the full set, but only sections 1, 3 and 5. To clarify the lines useful from time to time while polishing the surface to make easy pine rail along the entire length. Finished case flip deck up and along the axis to cut a groove under the rail cross section 5×10 mm, after which process the sealing bevels deflection of the deck surface. The feed detail is carved from lime bars with a thickness of 15 mm. the Nasal node is represented by an axial plate of plywood with a thickness of 1 mm, to which both sides are glued fake bars that has been cut to the required shape. Both parts are mounted on the glue on the foam body and, if necessary, domrabotnitsy.
Prihlas of wrapping paper cut into strips 40 mm wide that cover kazeinovogo glue and at an angle of 30° to the longitudinal axis of the body tight, close to each other is wound on a polished case. When will be closed the entire surface, place the second layer of paper in the opposite direction. Waiting for the glue dries, the hull sanded and the whole paste over with an additional layer of thin paper cut in the form of sheathing the decks, sides and bottom. Instead, it is allowed to fit the body on the casein thin nylon stocking, the excess after the glue dries cut off at the stern and the nose.
At the bottom is cut a groove beneath the keel plate and running the hole in the tubular bearing of the stock. The fin keel is cut from duralumin with a thickness of 2 mm or steel sheet with a thickness of 1 mm. of Lead ballast is cast directly on the bottom of the fin in a wooden Form or the workpiece’m going to fit to the fin on both sides of the screws with bolts and glue and then the saw round lead to the desired sizes and shapes. The sizes of lead pieces in this version, -1 2×40 mm (cross-section bars) and fastening screws — three pieces MB. In any case, the ballast weight must be equal to 1300 g, and the sectional shape is close to rectangular with rounded corners. When you view the model from below form of ballast — droplet.
Elements of the cabin are cut from plywood with a thickness of 1 mm, adjust to each other and are glued directly in the groove of the housing (installation begins with the sidewalls and “flooring”, then put the panel with front window and bulkhead, nrise is removable for access to radio). Simulated window cut out from glossy paper of the appropriate color. Their in-lakirovich already on the finished model.
Fin keel with epoxy glue in the slot of the housing and is additionally fixed in the volume of the cockpit with a hairpin length of about 30 mm. In indicated on the drawings places the joints of the plywood parts cabins or reinforce the frame rails with cross section of 3×3 mm. of the same rails and make special studs, the ends of which thread with glue attached metal lugs to anchor the rigging. Punctures the skin of the body in pre-marked areas, these studs are epoxy glued to full length in the foam.

pattern details
After curing of the binder proceed to the exterior of the housing. Initially applied one base coat of white enamel, after thorough drying which is applied a thin layer of putty. For a thorough sanding, a second coat of white synthetic enamel. Finishing layers two or three are placed without intermediate sanding. Color final decision yacht model depends on the taste of the manufacturer, however, it is useful to consider that the water is better visible parts with bright clear tones and shades.
Quality pine slats with a cross section of 10×10 mm vystrugivajut the mast of circular section, tapering evenly to the top end. Better results will give switching the billet of the two rails cross-section of 5×1.0 mm. Boom headsail and the mainsail is made from strips of 5×5 mm. On the mast and the geeks with the infirmity of yarn and glue fixed wire lugs and cut from sheet metal loop for attaching rigging and hinged attachment of the mainsail-boom on the mast. All wooden elements are slightly tinted and coated with varnish. In the lower end of the mast Reiki screw screw 2×15 mm so that his body was performed at 2-3 mm, and then cut off the head. Under the thus obtained spur of the mast on the deck is fixed Stasova plank made of aluminum or plywood, thickness: 3 mm
The sails are best made from a thin, but dense synthetic fabric. For cutting first helps from a dense paper to make patterns with allowances for advertka edges and the formation of the pocket under the mast on the mainsail. Painted patterns on the fabric along the received lines is applied a light coat of casein glue with a width of about 5 mm (it will bond the fibers and facilitate the cutting of matter). The width of the pocket, which the grotto will be worn on the mast should be approximately 40 mm. For the geeks of the sail are fastened from the bottom corners.
The mast is fixed in position by a pair of guys, for the forestay and afterstage. For these items of rigging used durable synthetic yarn or cord, of which the upper ends of the closed loop and the bottom are tightened using the notched tension bars of duralumin sheet thickness of 1-1,5 mm. For joining with metal loops all the body of the end lifting elements are on the ends of the wire loop of the eight. Deviations geeks regulates the length of the Scots, have a similar tensioner arm. To build the model directly on the water and adjustment of the rig is useful to assemble a folding stand made of plywood and battens section 5×15 mm.
