Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing floats such as a handmade float, and tools used therein.

[Conventional technology]

Today, the method of making floats using two pieces of float has become so common that when we think of helauki, we mean two pieces made of peacock's wings. The advantage of combining two pieces is that by dividing the originally flat sail into two pieces and pasting them together, you can obtain an ideal perfectly circular float with good physical sensitivity.
The advantage is that the bending of the blade itself can be corrected.

By the way, making an elaborate float using this method is
It is not an easy task even for an experienced person, much less an extremely difficult task for a sailor. However, anglers who enjoy making their own floats have a strong desire to make their own floats, and it has been hoped that a method would be developed that would allow any number of people to manufacture floats relatively easily.

[Purpose of the invention]

The present invention was made in response to such a request, and the purpose is to provide a method for manufacturing a float and tools used therein that allow anyone to easily manufacture their own float without requiring any skill. shall be.

[Structure and operation of the invention]

The method for manufacturing a float according to the present invention involves cutting two pieces of material such as a peacock feather shaft to the length of the float, cutting it in half into a semi-cylindrical shape, tapering the upper and lower parts, and then facing each other. , Press and fit the taper springs from the top and bottom to temporarily hold them and shape them. After shaping, remove the taper springs, apply adhesive to the mating surfaces, and put a toothpick on the top.
It is characterized by sandwiching the legs at the bottom and joining them together, then fitting the above-mentioned tapered spring again and drying them.The tool used for this is to hold a razor blade at a predetermined height from the bottom plate horizontally and against the direction of movement of the material. A molded wooden mold formed by forming a groove on the upper surface with a flat bottom in a shape that follows the contour of the float, and having both ends sloped smoothly down, and one or both ends. It consists of a tapered groove base in which a plurality of tapered grooves of different depths are formed in the groove, and a tapered spring for shaping. In the following examples, the method is carried out in the following order and using the following equipment:

■Cut the material to the length of the float.

The best material to use is peacock feathers, and choose two feathers that are the same thickness and have as little bend as possible. Then, cut them into desired dimensions.

■ Divide the material into two.

Of course, you can use a razor blade to cut the material lengthwise, but usually you use the bisecting table l shown in Figure 1. This bisecting table 1 is constructed by fixing blade clamping plates 3.4 on a bottom plate 2 at appropriate intervals, and fixing a razor blade 5 diagonally across the blade clamping plates 3.4. razor blade 5
is positioned at a predetermined height from the bottom plate 2. When using, insert the material between the blade clamping plates 3 and 4 (in the direction of the arrow),
Split in half by pushing forward. At this time, press the material against the bottom plate 2 with the curved side facing down. In the case of a peacock feather shaft, if you push it from the bottom (the base side), the filling will stand up or turn up, so be sure to push it from the top.

■Cut it into a semi-cylindrical shape with a taper at the top and bottom.

For this work, a molding wooden mold 6 shown in FIGS. 2 to 4 is used. A groove 7 shaped to follow the contour of the float is installed on the upper surface of the molding wooden mold 6.

As shown in FIG. 4, this groove 7 has a rectangular cross section and a flat bottom surface. Moreover, the front and rear of the molding wooden mold 6 are formed into gently smooth sloped surfaces 8.9.

Prior to this work, crush the upper or lower part of the material to be thinly shaved into a U-shape with your fingertips. After doing so, the material is fitted into the groove 7, and while pressing the material so that it does not float, the upper surface of the mold 6 is slid and shaved using a small force. At this time, instead of cutting the material all at once, the material is crushed into a U-shape several times, pressed into the groove 7, and scraped repeatedly to gradually fit into the narrower side of the groove 7.

During this work, since the groove 7 has a rectangular cross section, the material
It fits tightly inside and will not slide. Further, since the end of the molding wooden mold 6 is provided with an inclined surface 8.9, the end of the material is finished in a tapered shape. Once you have finished carving one side, start carving the other side in the same way. After that, in order to fit a toothpick into the upper end and a leg (regular row string) into the lower end, shave off about 3 to 4 mm of the filling at that part.

■The materials that have undergone the above processing are joined together facing each other.

After the machined surfaces of the two materials face each other and the toothpick and leg are sandwiched between them, taper springs 10 and 11 are fitted from above and below to temporarily hold them. The short taper spring 10 is for the head, and the long taper spring 11 is for the lower part. By using these tapered springs io and it, you can easily and reliably make the float fit into a perfect circle. Taper springs 10.11 are pressed into place by squeezing them with your fingertips. If you stretch it roughly, the float will become narrower and tighter, and if you fit it without stretching it, it will become thicker. In this way, after pressing and shaping the planks, remove the taper springs 10 and 11, apply an adhesive such as epoxy liquid to the mating surfaces, and attach a toothpick to the upper part and the legs to the lower part. Press and fit the tapered springs 10 and 11 again in the same manner as above,
Let it dry in that state. In addition, in order to shave the bamboo strips for the legs into a tapered shape, it is convenient to use a tapered groove stand 12 as shown in FIG. 5. This taper groove base 12
This is made by forming several types of tapered grooves 13 of different sizes on one or both ends, and by placing the tip of a bamboo stick in the tapered groove 13 and filing it with a flat file, etc., it is finished with a clean taper. Can be done.

■The float completed as described above is finished by removing any residue such as adhesive, and then painting as appropriate.

〔Effect of the invention〕

The present invention is as described above, and has the effect that even an amateur can easily manufacture floats such as snails, which have been considered difficult in the past, without requiring any skill.
