In small-scale production, as well as in everyday life, external threads are cut using a special cutting tool - a die. That is why any smart owner must have a universal die holder in his arsenal. By selecting dies you can adjust the diameter of the thread being cut. This article describes the features of using die holders and provides recommendations for their selection and operation.
DIY die holder made from waste material
This is what the product itself looks like.
In order to build such a universal die holder we need
: • tie rod end; • Tie Rod; • nut or bushing; • two M12 nuts; • bicycle chain; • piston pin.
Sequence of process
:
1
.
First, remove part of the rod (the one that is screwed into the steering rack). 2
.
Then you need to put the piston pin on the rod. 3
.
After putting on the finger, you need to put on a metal sleeve (suitable in diameter) or a nut, which we fix with a point on the nut. 4
.
Then, using a grinder, you need to cut off part (extra) of the steering tip. 5
.
After this, you need to weld two M12 nuts to it. 6
.
Then you need to screw the tip onto the rod. 7
. Next, you need to push a piece of chain through the nuts and weld it to the piston pin.
The die must be attached in such a way that it rests against the corner with a groove. If you do everything exactly, it will not turn.
Now you can cut threads of any diameter.

Manufacturing of accessories
A DIY pacifier holder with homemade beads looks stylish and unusual. In order for the result to meet all expectations, you need to decide on the shape and size of the fittings, since the final quality of the products depends on this. Polymer clay should be divided into several equal parts. A neat ball is downloaded from each blank. If you need to get a square-shaped bead, then the workpiece needs to be flattened on four sides. A plastic card is ideal for these purposes. The hole should be such that the thread can pass through it freely. For expansion, you can use a regular stack. After this, you can squeeze out the desired letters. If you have a silicone mold on hand, then you can build additional figures. The prepared beads are laid out on plain paper, which will prevent them from sticking. The preparations are baked in the oven for 20 minutes at a temperature of 120 degrees.

Business on maternity leave: how to make toys from food-grade silicone
Having once bought a toy made of food-grade silicone for her son, Muscovite Katerina Sheinrok literally fell in love with this material. That same day, she decided that she wanted to make baby accessories from silicone herself. A few months later, this hobby turned into a business with a small but constant income. The founder of the Solanos Kids project, Katerina Sheinrok, told the Biz360.ru portal about how silicone helps the development of babies and how to find your buyer in a highly competitive environment.
Dossier
Katerina Sheinrock
, 28 years old, founder of the
Solanos Kids
. She graduated from the Moscow Humanitarian University with a degree in psychology, after which she improved her qualifications in the psychology of pregnancy and parenthood. His main activity is organizing corporate trainings. Since 2016, while on maternity leave, she began making pacifier holders and baby teethers in her own project Solanos Kids. Investments in this business since the launch of the project amounted to about 200 thousand rubles.
How it all started
Katerina Sheinrok first saw silicone pacifier holders in 2015 at a market in Moscow. One of its participants sold teethers and pacifier holders made of food-grade silicone. This is a safe and durable material, tasteless and odorless, which does not stain and is not toxic. It is used to make pacifiers, nipples for baby bottles and chewers (toys that children put in their mouths while teething).
Most regular store-bought toys are made of plastic, rubber and wood. These materials have obvious disadvantages. Plastic can be bitten and rubber can be torn. Thus, the child may scratch the gums or swallow the torn part. In addition, not all types of plastic and rubber are safe for children. Wood is a more environmentally friendly material, but it is not intended for washing. If you wash wooden toys too often, they will begin to crack.
Products made from food grade silicone are soft, but at the same time durable. A child cannot damage this material. Since silicone toys are not afraid of moisture, they can be washed, boiled and sterilized. Katerina liked them immediately - both in appearance and to the touch. She bought one food-grade silicone toy for her son Roma. And after a few days I decided that I wanted to do similar things myself.
“Taking silicone toys into my hands, I realized that it was love at first sight, or rather, at first touch. But when I started to find out where all this was sold, it turned out that nowhere. By the way, when I asked that same girl at the market where she gets the materials, she didn’t answer me,” recalls Katerina Sheinrok.
Search for a supplier
To Katerina’s surprise, there was nothing like this in toy stores at that time. An Internet search led her to the AliExpress site, where food-grade silicone was sold. Delighted, the girl ordered a small batch “to try.” But the material sent turned out to be completely different from what Katerina expected. It felt different to the touch, had crooked seams and a distinct “synthetic” smell.
The aspiring entrepreneur continued her search. As a result, it turned out that this material is not produced either in Russia or in Europe. All certified food grade silicone is made in China in several factories. It is there that craftsmen from all over the world buy it.
“I don’t hide the fact that my material is made in China. Moreover, in China itself, in addition to the “official” factories, there are manufacturers of counterfeits. Apparently, their products are sold on AliExpress,” concludes Katerina.
She contacted several certified factories directly and asked them to send documentation for the material. All factories responded, and each had international certificates for materials. These documents indicate the quality and color of silicone, the absence of harmful impurities, etc.
“All my products are made from certified materials that meet international quality and safety standards. I do not buy “left” goods from resellers. The silicone I work with is truly suitable for children from scratch. It is odorless, tasteless and does not contain harmful impurities. What the baby puts in his mouth must be safe,” says Katerina.
She communicated with Chinese manufacturers via email or instant messengers in English. All documents provided by factories were also in English. Katerina made her choice among factories based on the information specified in the documents. Her mother Marina, who also knows English well, helped her with this.
Katerina Sheinrok registered a personal account on the website of the selected company, after which a manager was assigned to her. But making the first order was not so easy. The volume of the minimum batch with which certified factories begin cooperation turned out to be too large for the Russian woman. But after lengthy discussions with the managers of the enterprise, she managed to agree on a small trial batch weighing 900 grams.
“I don’t know how I was able to convince the Chinese to make an exception - probably the moon and stars aligned in the sky. I received the first small batch and realized that this was exactly the material I needed. It is distinguished by a velvety surface that is pleasant to the touch, elasticity, and the absence of seams,” recalls Katerina.
First toys
Chinese factories sell food-grade silicone in the form of toys and individual beads of various sizes and shapes: balls, cubes, hexagons, roses, stars, etc. Katerina made her first toys from the purchased batch of material. After that, she decided to further test the material. Taking several silicone parts, she asked her husband to tear or bite them. Despite all his efforts, he never managed to damage a single product. After this, Katerina realized that her toys were completely safe and could be put up for sale.
She made several things for her 6-month-old son, and then for almost all her friends and acquaintances who have children. She donated her products or sold them at cost to recoup the cost of the material.
Feedback from early customers has been generally positive. They liked both the material and the variety of colors of the beads. But shortcomings also emerged. It turned out that the cord used to string the parts was too thin. Therefore, the beads moved along the cord if it was pulled strongly. Katerina changed the cord to a thicker one. The beads sat tighter on it.
“We still have one of the first toys that I made for my son two and a half years ago. She's still like new. True, the nylon cord has worn out a little and is no longer white, but nothing has happened to the beads themselves,” notes Katerina.
After several months of working “for her own people,” our heroine decided to reach a wider audience and sell through her Instagram account. The first publication on the page appeared on January 16, 2016. Soon the first “unfamiliar” clients began to contact its founder – from social networks and through recommendations.
Katerina chose the phrase Solanos Kids as the name for her project. “I love the Spanish language. In Spanish, Sol means sun, Solar means sunny. And with a little linguistic adjustment, I came up with a pseudonym that I started using long before I started this hobby - Katrina Solanos. Therefore, when the question arose about the name of the project, I didn’t doubt it for a second - Solanos Kids. She herself came up with and drew her own logo, which also contains a smiling sun,” says the founder of the project.
Pause and new start
In the spring of 2016, the first batch of food-grade silicone came to an end. Before ordering new materials, Katerina Sheinrok decided to conduct a small monitoring of the market for silicone accessories for babies. To do this, she used a search on Instagram using her own hashtags - “pacifier holder”, “silicone teether”, “silicone beads”. The results discouraged her: there were a very large number of masters doing approximately the same thing. But they promoted more actively on Instagram, and they had much more subscribers than Katerina herself.
“It turned out that the competition in this business is simply catastrophic. My hands gave up and I stopped the order. I didn’t have that much energy and time to promote my project, and besides, in order to catch up with competitors, I had to invest heavily in promotion. But I couldn’t give any guarantees that it would pay off,” recalls Katerina.
The pause lasted about six months. During this time, the founder of Solanos Kids realized that she missed her hobby. But she was still not sure about his commercial prospects. The situation was saved by her husband Wilhelm. In the fall of 2016, he offered his help in purchasing material. As a birthday present, Katerina received a large 10-kilogram box of multi-colored silicone. This volume is enough for about six months of active use.
“I decided that I needed to try further. Maybe I won’t be among the top craftsmen who make such products, but I really enjoy the process itself. And I think I’m doing a good job,” admits Katerina.
At the moment, taking into account the first “trial” batch, she has already made three purchases of food-grade silicone. In total, about 200,000 rubles were spent on them. These expenses have already paid off, and in 2022 the Solanos Kids project began to make a small profit.
Play and develop
Pacifier holders and baby sling beads from Solanos Kids are silicone beads of different shapes and colors strung on a cord. Their creator has few working tools. This is a thick sewing thread with a large eye, scissors and a lighter to solder knots or ends of the cord. And, of course, fantasy.
Solanos Kids toys can be used from one and a half to two months of age. It is at this age that he develops a grasping reflex
“My products are useful not only as teethers. This is also an excellent simulator for developing fine motor skills. And from a psychological point of view, a baby’s sorting of beads of different sizes and shapes affects the development of speech and consciousness. Using my son as an example, I can say that he spoke quite early,” explains Katerina.
How work with clients is structured
The majority of clients are young mothers under 35 years old. They tend to order products for their children through Instagram. Market visitors often buy these toys as gifts for relatives and friends who have children.
Some of the buyers have already become regular customers. Some of them return for a toy of a different design to diversify their choice, while others return for gifts for friends. Katerina is especially pleased when her clients come for repeat purchases for their second baby.
Work on one order takes on average two days from the moment the application is received. Communication with customers occurs through messages on Instagram, email, and instant messengers. When working on an order, Katerina always specifies the child’s gender, age and color preferences.
After this, the founder of Solanos Kids makes three or four “mock-ups” of the product. She lays out beads in several versions and sends photos of them to the customer. The client chooses what he likes and, if necessary, makes adjustments. Sometimes it happens that the final result is much different from what the customer wanted at the beginning.
Orders are sent to non-resident buyers by Russian Post. Katerina is pleasantly surprised by her work. During the existence of the project, there has never been a case of undelivered or long-delayed parcels. When sending an order, the businesswoman sends the client a tracker number, using which the parcel can be tracked on the Russian Post website. She also monitors the fate of each shipment and warns the customer when the purchase is delivered to his department.
Most orders arrive before the New Year holidays. In December 2016, Katerina sent up to 10 parcels a day. Another peak season occurs at the beginning of summer. There are fewer online orders in spring and fall. But during these periods there are usually many festivals and design markets.
Prices are higher, the material is better quality
Prices for products depend on their type, amount of material and complexity of work. On average, pacifier holders cost 500-700 rubles, holders with a rodent - 900-1100 rubles. Sets in the same style (beads for mom + holder + rodent) will cost the buyer 1200-1600 rubles.
Discounts are periodically applied to finished products displayed on the Instagram page and then they may cost slightly less. But, as practice shows, about 90% of buyers on Instagram prefer to order an individual item.
Payment occurs after agreeing on the order itself and its delivery methods. The cost of sending goods by Russian Post is usually 180-250 rubles, with the exception of cities very remote from Moscow. Within Moscow, courier delivery will cost approximately 300 rubles. You can pay for your order by card or cash to the courier.
According to Katerina herself, her prices are average on the Moscow market. Products made by craftsmen from other Russian cities may cost less. However, about 40-45% of purchases through Instagram go outside of Moscow. Among the cities where Solanos Kids products were delivered were Tyumen, Kazan, Rostov, Krasnodar, Sochi, Murmansk. Several orders were from abroad - Kazakhstan, Germany, Spain, France.
“We often hear questions about price. The same AliExpress offers similar products at a price 2–2.5 times lower than mine. And naturally, customers periodically ask me about this. But if we are talking about products for children, they must be certified. I am responsible for the quality of my materials. And ordering on AliExpress is like taking a pig in a poke,” says Katerina.
Marketing and promotion
The main channels for promoting the project are Instagram, Facebook and participation in markets. Most often, Katerina Sheinrock's products can be found at the Seasons market, which is held once a quarter. The founder of Solanos Kids has already participated in five similar markets. Renting a place at this event is more expensive than at most other festivals, but the purchasing power of market visitors, according to Katerina, brings good results to its participants.
“About a week before the market, my busy time begins. In high intensity mode, I collect pacifier holders, chewing bracelets, and beads, which I will then offer at the market. Here I have an endless flight of imagination - I collect variations to suit my taste. But I select most of the colors taking into account the season. “New Year’s” toys use Christmas red-white-green combinations or white-gray-blue winter ones. In summer, brighter colors predominate: yellow, pink, orange, green.”
The entrepreneur also uses affiliate promotion. One of the clients, who herself works in children's textiles, suggested Katerina release a joint collection. After that, they talked about each other on their Instagrams.
Quite a lot of clients come through recommendations. “It’s especially valuable to me when customers come on the advice of friends. Sometimes “chains of recommendations” include up to four people: the first recommends to the second, that to the third, etc. It's really nice. Many clients remain my subscribers, even though their children are too big for these toys. But they continue to leave comments and likes,” adds Katerina Sheinrok.
Work and hobbies
Until recently, Katerina was engaged in making accessories during the day, when her son Roma had “quiet time,” and also at night after he went to bed. At the beginning of 2022, she went to work in the office on a standard 5/2 schedule. Now you can only do creative work late in the evening and at night, when the child is sleeping.
Katerina does not yet see any problems in combining work and hobbies. “For me, working with silicone is a pleasure, a way of relaxation. Food-grade silicone is a truly pleasant-to-touch material. I am a kinesthetic person, and tactile sensations are important to me. All day at my main job I have to solve serious problems. And of course, in the evening I want to sleep, but I get a second wind for my hobby,” admits Katerina Sheinrok.
She returned to the same company where she worked before going on maternity leave. Her field of activity is organizing corporate trainings. According to Katerina, her main job experience helps her in communicating with Solanos Kids customers. There she communicates daily with clients of different levels and areas of activity.
“I have quite warm relationships with many clients in my day job. About a third of my clients are friends with me on Facebook. They see that I have a hobby and are very surprised, because these are two completely unrelated areas. But for many, it’s a plus that a person, in addition to work, also has an interesting hobby,” says Katerina.
What's next
The immediate plans include a gradual expansion of the project’s audience. Today it is no longer just children under one and a half years old. For example, one of the customers, along with teethers for the baby, ordered a keychain for a backpack for her eldest son. Other completed orders include sets for girls 5-6 years old in the form of beads or bracelets.
“I am most interested in expanding the audience within the framework of this project. I already have a good assortment of holders for pacifiers, teethers, chewers, bracelets and beads for mom’s neck, which the baby can also chew on. At the same time, I understand that, in principle, you can make anything from this material: keychains, holders for a name card for a school backpack, and rosary beads. Silicone is just as pleasant to handle in your hands as wood or stone,” says Katerina.

How to cut a thread using a die and die holder?
Die holders are necessary for thread cutting; they are made of high-speed steel R6M5. It ensures the strength of the tool, reliability and durability of its operation. GOST allows the manufacture of devices from carbon steels. Their disadvantage is fragility. When processing workpieces made of hard alloys, they can simply break off. The main area of application for die holders made of carbon steels is the processing of non-ferrous metals or alloys with low hardness. They are also good for re-passing and fixing broken threads. For cutting pipe or conical threads, special thread-cutting devices are used.
Product on a clothespin
At the first stage, you need to arrange the beads in the right order in order to know exactly the order of assembling a personalized pacifier holder with your own hands. The fittings are strung on a cord, the length of which must be at least 22 centimeters. The base should be a little longer, as it will be folded exactly in half. The tip must be melted with a lighter so that it becomes hard and sharp. One side of the cord must be tied into a knot. The classic length of the loop is 8 cm. You can hide the knot with a protective bead. First, simple fittings are strung, and then blanks with letters. All that remains is to secure the clip. The cord is threaded through the retainer ring and three knots are tied. They must be scorched with a lighter and hidden in beads.
Variety of models
Today, not only the baby’s parents, but also a caring brother or sister can make a high-quality pacifier holder with their own hands, since there is nothing complicated in this task. But before you begin the most important stage, you need to decide what accessories there are for pacifiers:
- Stationary suspension. This option is convenient because the product will always be at hand. The device allows you to discipline the baby, since many children even after two years indulge in nipples. At this age, the child is able to remember exactly where his favorite pacifier is located, so that after use he can hang it back in place (when he needs to eat or take water procedures). To make a stationary pendant, use a wide tape, with Velcro attached to one edge and a small ring to the other. You can make such a pacifier holder with your own hands in just a few minutes. The finished pendant is attached to a crib, bedspread, or clothing.
- Pin. This is the most popular type of holders. The pacifier is always at hand, regardless of where you are (in the house, on the street, in a clinic or at a party).
How to properly handle mechanical and manual options?
One of the most important structural elements of the die holder is the adapter sleeve in the tailstock quill. There are two fingers on the body and the end that absorb the force during thread cutting. When using split dies, the release adjustment is carried out using a screw. The type of die holder is selected depending on the direction of the thread being cut.
Holders may vary in design. A floating design is considered the most optimal.
When working with round tools, a self-aligning holder is used, which ensures thread cutting according to class 2 accuracy. This design makes it possible to eliminate the displacement of the axis of the die and the workpiece, as a result of which the thread may have a smaller diameter or have inaccuracies, distortions and other defects. During operation, translational movements are performed by the head, while the die holder and ring maintain their position, remaining motionless.
Fixed levers are fixed to the frame. The longitudinal movement of the tool is limited by screws. The limited distance is defined as the amount required to change the combs and self-open the head. When working with round dies, they are installed in the socket. The handle is attached to the collar using sockets with an angle of 60°. The adjusting screws rest in the 90° sockets. During operation, they shift relative to the axis by the required distance, thus compressing the threading device.
When installing thread-cutting devices on the machine, you must ensure that the fastening is not rigid. The swinging die holder does not affect the quality of the thread, since the threading tool is installed along the axis of the workpiece due to springs. Reliability of fastening in the machine is ensured by special cutouts on the body at an angle of 60° and 75°. These protrusions help prevent the skewer from skewing during operation. Cutting is carried out by rotating the workpiece.
The downward movement is limited by a stop located at the lower end of the holder, and the upward movement is limited by a stop at the upper end. When working with hand-held devices, for example, when cutting small-diameter threads, the blade fixed in it is brought to the workpiece, and the handle of the holder rests against the caliper. The rotation must be even to prevent thread distortion.
Design and principle of operation of clamps
Compared to a die, a die is a simpler product. The die is a one-piece tool and is made entirely from expensive high-speed steel grades. Klupp is a prefabricated structure. Its body is made of ordinary structural steel. And already cutters are attached to the body for cutting inch threads on the surface of the pipes. This design allows for more efficient chip removal, which extends tool life.
The principle of operation of the die is similar to the principle of operation of the die. By rotating the tool clockwise, threads are cut on a cylindrical surface. By rotating in the opposite direction, the tool is unscrewed.
Classic master class
Making a stylish pacifier holder with your own hands using a photo is not so difficult. For a clear example, you can study the video of craftswomen. To work, you will need a strip of ordinary knitted fabric or cotton fabric 4 cm wide and 50 cm long, a piece of fabric and non-woven fabric, and an elastic tape 300 mm. For fixation, a clip with a decorated tip and a chalk pencil are useful. The ends of the strip need to be tucked to a width of one centimeter. A neat stitch should be laid at a distance of 2 cm from the edge. On one side, thread the threads into the eye of a darning needle and tie tightly.
Interesting idea
This option is suitable for creative mothers who love to do handicrafts. You can make a pacifier holder with your own hands, and even with homemade beads, in just 1-2 hours. You just need to prepare everything you need in advance. To make beads you will need polymer clay. Main nuances:
- Material. When buying children's polymer clay, you need to make sure that the packaging contains information about safety and certification.
- Acrylic paint. It will be useful for coloring letters on beads.
- Silicone mold. This is a classic shape for creating a desired shape or simulating texture.
- Knives, stacks, plastic card, pin.
It is worth noting that the necessary letters must be squeezed out on uncured clay with an ordinary wooden stick, a stack or a toothpick. Only after complete hardening can paint be applied.
How to use a tool to cut a thread on a pipe?
The die holder is also used for cutting pipe threads. It differs from metric in its dimensions. In this case, it is better to use dies rather than dies as a thread-cutting tool, since the latter have a special entry into the pipe. In a simplified form, working with clamps can be described as follows. The clamp is fixed in a die holder (similar to a die) and put on the pipe. After this, you can begin threading.
To secure the clamps, it is better to use a die holder with a ratchet, which is not suitable for working with conventional clamps. You can also cut pipe threads using special dies (J or K), but working with them is somewhat more complicated, since, unlike dies, they do not have a special entry. To prevent distortion, a small chamfer is removed from the pipe, after which a pipe line is installed.
The principle of working with the tool is very simple. The die or clamp is secured in the holder body with screws that ensure reliable fixation. The steel coupling on the tool body has an internal thread through which the sleeve is screwed in. Three nuts welded to the sleeve are used to install stopper bolts. The diameter of the sleeve is selected so that the pipe being processed easily passes through it.
The device is screwed onto the bushing so that the distance from the coupling to the end of the thread on the bushing corresponds to the length of the area being processed. After this, a pipe is inserted, which should rest against the die with its end. After installing and adjusting the position of the pipe, it is locked with three screws. Rotation is carried out using handles, as a result of which the coupling with the die is screwed onto the sleeve, ensuring the movement of the threading tool with the required pitch.
A holder with a ratchet is also more suitable if threading needs to be done on a pipe located in a hard-to-reach place or against a wall. Even in this position, the ratchet tool does not need to be constantly rearranged. Using such a die holder, you can even make specific threads with your own hands.
Die holders for round tools are manufactured in three sizes:
- type I - for thread-cutting tools with an outer diameter of 16 mm;
- type II - for leks with an outer diameter of 30 mm;
- type III - for dies with an outer diameter from 25 to 200 mm.
In addition to their sizes, die holders differ in their scope of application - manual and machine, as well as in the number and location of the clamping screws. Placed at an angle of 60° are used to fix the dies. Other screws located at an angle of 90° are offset axially from the center of the die and are used to adjust the thread diameter.
Basic Concepts
As the name suggests, a universal die holder is designed to work with dies. The tool itself is made of ordinary structural steel. But special requirements are imposed on the cutting tool (die). In the process of work, he experiences enormous loads. In addition, in the cutting zone, the metal surface is heated to 500-600 degrees Celsius. Therefore, for the manufacture of dies and taps in Russia, high-speed steel R6M5 is used, which contains up to 5% molybdenum. It is thanks to the content of this chemical element that steel has such high wear resistance and red brittleness.
