How to make a screw?
Aviamodelirovanie - quite an interesting hobby. In aeromodelling you can learn differently, for example, how to make a screw. This skill is very useful, since screws break often, so there should always be a worthy replacement. So, how to make a screw yourself? Let's start by searching for the right materials.
Materials
- Blank for the screw. It is best to use wood, because it is stronger than plastic, and looks more presentable.
- A similar piece of foam. It is better to use colored material.
- A simple pencil.
- A sharp knife, you can prepare and clerical.
- Sandpaper.
- Nadfil.
- Punch or drill (with emery wheel).
- Old screw aircraft model.
Preparation
Before making an air screw, you need toprepare all the details. First, it is necessary to cut out the workpiece of the screw from the foam according to the sample of the already existing one. Circle the old screw with a pencil, applying it so that the front part of its profile lies downwards. Now you can cut the workpiece, it will not be needed, you need the part that you cut out of. It will help make the screw volumetric. Now in the hole in the foam plastic, put the old screw, press the foam so that the screw leaves dents. So you can know the thickness.
Now you need to cut the workpiece, keeping the length andthickness of the real screw. It is also necessary to attach the middle, circle and cut with a stationery knife, and sand it with sandpaper. There should be three blanks: the left and right parts of the propeller, its middle.
Screw manufacturing
The workpiece must be attached to the wooden,draw a pencil, then it will only be necessary to use the nail file and cut out the screw. With the same tools, you need to remove excess wood to make a real screw from the workpiece. According to the drawing, you can remove the tree, walk from the middle of the screw, making zigzags. Now you need to use a drill with a grinding wheel to polish the screw before using it for the intended purpose.
That the screw turned out correct, approached toyour aircraft, you can also use the drawings and instructions. The screw can be manufactured not only for aircraft models. If you are interested in the question of how to make a propeller for an aerosleigh, you can see the detailed instructions here.
