Construction of a model out of paperboard Elements
The fuselage (e.g. of a plane with a piston engine)
There are several methods for construction of a fuselage.
Method of the segments / frame towards a frame
The fuselage is divided into several segments, or each segment is limited by a frame (at each end).
For joining of the frame on paperboard (reinforcement of the frame) of a given thickness (1 to 2 mm) and cutting, it is necessary to join the two twin frame (face printed towards the interior) and to sandpaper the whole with sandpaper (nr.120 or +) to obtain the two identical frame.
To place and gluing correctly a frame, one always refers to a black feature on the part of covering and the central feature on the frame.
Not to confuse ''the bottom'' and ''the top'' of a frame !
For joining of the segment, but before the complete assembly of the fuselage, it is necessary to equalize (to sandpaper) the two ends of each segment with sandpaper (nr.120) stuck on a surface punt (fixes sandpapering).
This will allow, during the assembly of the fuselage, to have all the segments aligned and adjusted goods.
Method a frame and of a part of jonction ( glue togeather)
The following method is not very different, with share which the fuselage is not divided by segments with two frame at each end.
Here the preparing stuck in form of a cylinder (rings) correspondent to a part of the fuselage cylindre/segment joined the other using a paper plate (part of junction) stuck inside. It is in a cylinder thus prepared that one slips and sticks a frame (only one frame for two segments).
Another method is based on a carcass of the fuselage which forms a unit on which frame are stuck.
This technique requires much more attention and a work looked after during construction (assembly in the axis, overall rigidity) and covering of the carcass.
In practice, you can also meet a mixture of these methods.
Part of the fuselage can be based on couples and a part on a carcass.
