Nowadays, computers and laptops have replaced many drawing tools. But recently designers, technicians and copyists used pencils, rulers, compasses, reydepery, protractors in their work.
Description and device tool
The device tool is simple. It consists of 2 spring-loaded plates fastened with a screw. It serves as a kind of carcass trap, which is supplied from a special can. The thickness of the lines is governed by a nut with a notch. In addition, there are glass raidfinders. They have tubes of different diameters, thereby adjusting the thickness of the lines.
Types of raider
- Metal riser with adjusting nut.
- Glass razpeder.
There is a GOST (28950-90) which regulates the first group of metal devices:
- Wide with separating nut.
- Raisefeder with dividing nut.
- Curve rispeder.
Rapidograph is a pen for drawing. It consists of a tube containing a can of ink. Also inside the tube there is a needle through which ink or mascara is fed onto the paper.
Now hand tools are practically not used in practice. Computers simplify tasks in drawing work dozens of times, reducing the time required to complete drawings. Around the end of the 90s of the 20th century and at the beginning of the two thousandth, rapidographers and reizfedera izograf turned into museum exhibits and collection items.
Although earlier this tool was a symbol of the profession. A quality drawing tool determined the results of the drawing as a whole. The works performed by the rapidograph were more technical, accurate and accurate.
Now the drawing tool is used only for training in artistic graphics and calligraphy.
Calligraphy involves making beautiful handwriting. Now this area is used for writing invitation cards and wedding greetings, as well as in graffiti. Sometimes calligraphy is used in television to decorate various screensavers.
Step-by-step instructions for use
Before you begin, you need to make sure that the endfender is correctly sharpened. Otherwise, the drawing will be poor quality, the lines are blurred, blots will appear. I also advise you to purchase a special can for ink.
The procedure is as follows:
- Remove the cork and fill the can with ink or ink by about примерно volume.
- Close the cork.
- Open the cap.
- Using the adjusting nut, create the necessary clearance between the plates to set the required thickness of the lines.
- Fill the gap between the plasterboard plates with ink from a tube on the cartridge.
- Attach a ruler to drawing paper or tracing paper to the place where the line starts.
- Draw a line of the required length with a reedfeder, without tearing it from the paper.
- The process is repeated until the mascara between the plates ends (this is about 3-4 lines, depending on the length).
- If the lines are very long, there will be 1 line.
- Repeat the ink charging process.
- If necessary, adjust the thickness of the lines with an adjusting nut.
How to draw reedfeder
It is easy to learn. You just need a little patience, practice, and a couple of dozen ruined drafts.
To begin with, learn to hold the tool correctly: straight, without tilt angles. To avoid blotting, do not make a large gap between the plates. Do not collect a lot of ink, make sure that it does not dry out. If the mascara has dried, wipe the end of the pen with a soft, lint-free cloth.
It is best to use a special ruler that prevents the ink from getting under it. If there is none, stick a narrow strip from another ruler to the wooden ruler.
Draw horizontal parallel lines first. Then wait for the mascara to dry and change direction: draw vertical or inclined lines.
Sometimes difficulties arise when drawing thick lines. Then they do this: at first, 2 thin lines are drawn, and the space between them is filled with ink later. So the drawing will look neater, and less likely to spread ink.
How to pluck eyebrows
Few people know that the redefeder is not only a drawing tool, but also a cosmetic one. Inventive Soviet women used it to pluck eyebrows. This tool is able to capture any, even the smallest hair.
Small dimensions allowed to carry it in a pocket or a small cosmetic bag. The advantage over tweezers was that tweezers could damage the skin if you grabbed a few hairs. By resorting to the help of this tool, it was possible to achieve excellent results.
Despite the soreness of the procedure, women successfully applied it to create a line of eyebrows. Before starting the procedure, the eyebrows were smeared with a thick cream, brushed with a brush, then a contour was outlined with a black pencil, and the excess hair was plucked.
Care tips and useful information
- Before starting work, make sure there is no dried paint or ink on the plates.
- Do not overtighten the adjusting nut to avoid breaking the thread.
- At the end of the work, wipe the redefider with a cloth, removing the remaining carcass.
- If the tool is blunt, sharpen the ends of the plates with emery paper or a file.
The first redefere appeared in the 18th century. They were used to create drawings and geographical maps. It should be noted that the word has German roots (Reißfede). Otherwise translate: reißen - draw, fede - pen.
To work with the tool you need to carefully, otherwise the mascara can spread, form a blot, which will lead to the unsuitability of the drawing. Inventive designers came up with other ways to work with mascara. At about the 20s of the last century, others appeared, rapidografy devices.
We got acquainted with how engineers of past generations performed complex drawings. Now this is done with the help of a computer: if before each node had to be performed separately, now a smart program can copy an element that was previously executed.
In the past, the slightest mistake made the drawing unusable. The computer allows you to make amendments. But we must bow and pay tribute to this old, faithful assistant of all the draftsmen. Thanks to the reedfeder in the hands of brilliant, patient, tidy engineers and designers, a huge number of machines and mechanisms were invented and created, and structures were built.
