ON THE SIMPLIFIED TECHNOLOGY

The peculiarity of the proposed model-class submarine EL-500 (Fig. 1) the fact that her body is going from flat wood blanks. Thus it was possible to get rid of difficult for beginners operations for excavation of the buildings of the entire wooden bars. Now the model takes five plates of length not less than 450 mm and a cross section of 10X45 mm (one of them is used for the case cover).

Two plates are cut along the contour so as shown in figure 2. In the plane of the future intersection on the axis of the knife cut a groove of a stern tube. The remaining billets are processed only in the external contour corresponding General arrangement drawing of the model “side view”.

 

After the gluing of the wooden plates in a single billet it on the cardboard template with a carpenter’s tool handle, and then pull the housing cover (manhole). During the joint cover profile is fixed to two nails, instead of them subsequently set screws M3 included in glued and the hull nut. The cabin is made separately and mounted after the machining of the housing.

Tuskuru all the elements of the model, made of wood, they are several times impregnated with a liquid diluted with nitrocellulose adhesive (complete drying of the previous coating does not need to wait, otherwise sasajkovski glue will close the pores of the wood and will not allow the part to go deeper). After drying the “primer” model prosceniums, is nitro, then putty should new treatment with emery paper of different grits and final painting. For the filling you can use talcum powder, spiced on the liquid nitro.

The stern rudders are cut out of plywood and glued after the finish of the epoxy resin in the respective notches in the body, not reaching the depth of a stern tube.

 

Hydroplanes — tin. Axis for them are pieces of wire of Ø 3 mm. From one side of the workpieces axes of the tapped M3 on the other wire propisyvaetsya along and slit are mounted on glue or soldering surfaces. The threaded shanks allow screw axis in the housing, if necessary, changing the angle of the rudders.

 

Propeller shaft and bow hook hanging rubber motor wire Ø 3 mm. the Last lock nut M3 and epoxy resin, the propeller shaft to hold the two nuts M3. They form the “tide” to carry out cuts at the installation of a tin of the blades of the propeller screw. Node probivaetsya carefully applying the soldering acid.
