For various training childish sports and applied types of creative activity in the form of visual aids for an explanation of material can be required to stick together a volume triangle. This task is not especially difficult, however demands accuracy and care when performing separate operations.
Instruction
1. For a start it is necessary to prepare preparations for future product. For this purpose on paper, cardboard or any other material draw two identical triangles of the necessary size. They should not be located densely to each other as further it will be necessary to finish drawing these figures. Isosceles or equilateral triangles at which either two, or all three parties are equal will be best of all to look.
2. After that finish drawing to the received figures the straight lines going from triangle corners outside so that they divided a corner which leave, half. Length of the line has to correspond to thickness of future volume product.
3. Having noted the necessary length of lines, construct one more triangle which has to turn out like an internal figure of the received three points, is only thickness products more. It is necessary to do it with each of two triangles which will be the front and back parties of a figure subsequently.
4. Further accurately cut through the lines going from tops of a smaller internal triangle and bend an internal figure on lines of a contour. As a result the figure of the necessary size behind which there are allowances for product thickness turns out.
5. At the end it is necessary to connect two received triangles, and the available allowances forming sides of a volume figure have to enter each other.
6. Cut corners of allowances and cuts, then insert each other that they did not support detail contours. Having carefully tried on two halves of a product, miss the mark allowances for thickness with PVA or other glue for the used material and, having connected half, stick together them.
7. If dense material which is not glued at once is used, connect two of the parties of a triangle and record seams paper clips. When the parties dry out, it is possible to stick together also the third edge.
