How to make a key from a bicycle chain

DIY bicycle chain bracelet

make, bicycle, chain

A textured and rough men’s bracelet can be made from a bicycle chain with your own hands. The starting materials for such a decoration will take a little, as well as the time for assembling the bracelet itself.

From one bicycle chain, about five to six bracelets are obtained, depending on the girth of the arm.

Step 1. This is the most time consuming stage of the work. The bicycle chain must be thoroughly washed and disassembled.

Step 2. Cut off two leather cords. Their length should be about one and a half meters.

Step 3. Through one cord it is necessary to thread the button and stop it exactly in the middle. On the second cord, it is also necessary to mark the center and tie it to the second cord in a regular knot. As a result, four equal lengths of the cord should depart from the button.

Step 4. Tie all four cords into one knot, tightening it as close to the button as possible.

Step 5. Now you need to weave two small rings from the chain. Divide the cords in two and pass them through the rings towards each other, tying in a knot.

Step 6. It’s the turn of the chain links. The cords must be split in two. In each of the parts, they must be threaded through the hole in the link towards each other and tied into a knot.

Step 7. The links now need to be positioned in a different way. The principle of threading the cord is the same, but the links should be laid crosswise.

Step 8. Next, it is necessary to weave, alternating one link and the links crosswise and so on until the end of the bracelet.

Step 9. At the end of weaving, the cord should be tied in a knot, leaving a loop. It is necessary to thread a button into it, woven from the other end of the bracelet.

Step 10. Cut off the excess ends of the cord, you can completely or leave them in the form of a brush. At the end of such a brush, if you wish, you can fasten large beads.

Main features of bicycle chain maintenance

The bike chain is one of the most important parts of your bike, so not only the overall riding experience, but also your safety depends on its serviceability. That is why every cyclist should definitely know how to carry out basic manipulations with the chain, namely the process of pulling and removing.

How to Tension Your Bicycle Chain?

Regardless of whether you have a high-speed bike or not, you can pull the chain yourself without the involvement of specialists. The main thing is to have a standard set of tools at hand. If we are talking about high-speed models, then most often tension problems arise due to a violation of the stiffness of the rear derailleur spring. In order to tighten the chain, you will need to perform the following sequence of actions:

  • Stretch the chain tightly around the largest chainring and smallest sprocket. At this point, the rear derailleur is pushed as far forward as possible and it becomes possible to add two links. This way you get the optimal chain length.
  • Alternatively, the chain is thrown to the largest chainring and smallest chainring. Next, we pull it up to the position until the rear transfer frame begins to show exclusively down.

How to remove and reinstall a bicycle chain?

DIY Bike Chain Bracelet | Mr. Kamdo’s Style

First of all, let’s look at those life situations that involve removing the bicycle chain:

  • The chain needs to be cleaned from dirt. Such cleaning must be carried out systematically.
  • Individual chain links have been damaged and need to be replaced
  • The chain is completely worn out and you decide to replace it with a new one.

Before proceeding with the removal of the chain, carefully inspect the entire configuration and try to remember how all the elements are connected to each other. If you have no experience in removing the chain, and you do not rely on your memory, you can carry out the process of photographing. Removing the bike chain is only possible with certain tools. This set necessarily includes:

  • A key to help remove the rear wheel
  • Pliers
  • Chain squeezing

Before proceeding with the removal of the chain, be sure to clean it from contamination with a clean cloth soaked in a special solution or white spirit. The rear wheel can be removed. It is not necessary to do this, but it will become much more convenient to work this way. With the help of squeezing, carefully squeeze out the pin and disconnect the extreme link. After that, we just take it out of the switch. In order to install the circuit back, you must use the same procedure. Bring the chain back to its original place and reassemble the overall structure in its original form. Even if you did not have any special tools at hand, especially for squeezing, do not despair, because the procedure for removing the chain can be easily carried out with the help of improvised means. For this, ordinary pliers or a hex wrench are quite suitable. The only caveat is that the process of removing the chain will take a longer time. If you own a chain with a lock, then it is quite easy to remove it using such simple tools as a dense rope or cable. This will allow you to carry out the process of removing the chain in a place far from home if the chain fell off or was damaged during a bike ride.

Making a universal wrench

For the first two methods, you will need the following materials:

  • An unnecessary bike chain, even a rusty one will do. Count on a length of 1.5. 2 m;
  • Wooden block or square metal tube. The thickness should be reasonable so that you can grasp the object tightly with your hand. Optimal dimensions: 25 x 25 mm, length 30 cm;
  • Long screw and nut;
  • Drill corresponding to the diameter of the selected screw.

So, having decided on the tools, let’s move on to the algorithm of actions, taking a wooden block as a basis:

  • Clean the surface on which you will work and take all the necessary set of materials;
  • Start with a bar. Measure the line so that the length is slightly longer than the width of your palm. Carefully cut the measured piece;
  • Take the resulting blank and mark the places for the chain attachment. The distance of the marks should be 2-3 cm from the edge;
  • Select a drill that matches the diameter of the selected screw and drill through holes in the marked areas. Screw the screws into the holes;
  • Go to work with the chain. It needs to be opened: to do this, find a collapsible link and use an awl or other thin sharp object to remove the locking pad;
  • After you have opened the chain, put the extreme link on the tip of the screwed in screw, fix the mechanism with a nut and tighten it well so that the structure does not fall apart;
  • Allen wrench ready.

If you use a metal bar, then the algorithm will change a little: you need to immediately take the chain and attach it to the outer edge of the pipe, calculating 2-3 links. Fix and weld with a welding machine.

The third method is a simplified version of creating a universal wrench, which requires a minimum of materials, but will be less compact and convenient to use. You will need the following tools:

  • Extended nut M12;
  • Long bolt M12;
  • Bicycle chain.
  • Start working with the chain. In the first step, find the place where the chain meets and knock out the inner roller. To do this, place a nut under the required link and knock out the mechanism with a drill and a hammer;
  • When the chain is disassembled, proceed to the next step: it is necessary to connect the extended nut and the chain. Place the main part in the center and wind the ends of the chain on both sides, so that they are parallel to the nut;
  • Fasten the structure in a vice and weld the joint using a welding machine;
  • After the workpiece is made, screw a long M12 bolt into the nut. It will act as a retainer and adjuster of the required hole size.

How to make an allen wrench from an old bicycle chain

Many objects in everyday use can be given a second life. Using an unnecessary chain and with a little effort, you can make an all-purpose wrench that will last more than one year and will solve many problems on the farm.

How to Use a Allen Wrench and What It Can Do

The principle of operation is quite simple, so the manufactured wrench is suitable for many areas of activity. It all depends on what size of grip you choose: put on the tail of the screw that link of the chain that will create a loop of the size you need.

In the case of a key that is made from a nut, a different tactic is used. To unscrew the desired nut, throw a chain over it and tighten the bolt to the limit. Thus, it will fix the position and help to twist the object without effort.

As for the functionality, it is limitless. Having chosen the desired diameter of the loop, you can open the abutting stopper of a plastic or glass bottle, unscrew the nozzle of the old tap, even if it is already rusted, unscrew a bolt or nut of any size.

Such an item will always be relevant for work in the garage, when it is necessary to quickly fix or remove a well-fixed part in the car. Simply place one or more loops over the desired object and scroll without using too much effort.

To summarize, I would like to note that the universal wrench can be made following three methods. Rely on your budget and layout and use an unnecessary bike chain to craft useful household tools.

How to make a universal wrench from a bicycle chain

A real master does not lose anything, everything goes into action. A useful tool can literally be made out of junk, and you wonder how such a thing can come in handy. And much of what you do with your own hands will last for many years. Take a bicycle chain, for example. You can make a hot stand out of it if you roll up a ring, a vase, a candlestick, an original photo frame and even cufflinks. Or. a versatile tool that will come in handy in the workshop. If this option suits you, then by all means check out the experience of the author of the YouTube channel Creates DIY. He proposed to make a key out of this material that is able to cope with very difficult tasks.

How to assemble a key from a chain: step by step photos

To make a key, not the whole chain is needed, so from one piece you can make a couple of keys and share your homemade product with your friends.

This completes the work, the key is ready, and you can use it immediately.

What you need to make a bike chain universal wrench

Of the skills, the ability to work with a welding machine will come in handy. As for materials, prepare a long bolt and a large nut or threaded stud. It would also be nice to find a comfortable wooden handle.

In addition to the welding machine, you will need a handy vice and pliers. All work will take half an hour.

How to use the master key

This wrench is useful for unscrewing a large diameter part.

Such a universal wrench will also come in handy in plumbing work. To unscrew the pipe, you can not weld the chain to the nut on both sides, but fix it only on one side, and make a strong hook on the second. Then you just throw in the chain, fix it with a hook and you can use the key in the most difficult to reach place. Instead of the hook, you can use the same chain lock that you removed originally. Users who repeated this experience noted that it is very convenient to unscrew the oil filter in the car with such a tool.

And here is another modification of the same key, perhaps it will seem more practical to you:

Which is better key or puller?

I express my experience. Personally, I always use the simplest key, the first item on our list. Why? YES, simply because (as I already wrote) it is cheap, and it is easy for them to crawl on almost any engine.

For example, other options, where they are thrown from above, may be inconvenient only because there may be no room, and it is banal to wear this head (or “cape”), and if you do wear it, it will be inconvenient to twist (or practically impossible).

The situation is the same with oil filter removers. they can be easily thrown on. BUT again, to tighten, there may not always be a place!

The oil filter is not easy to remove, even if it is hand-tightened. It has a rubber gasket, which is tightly pressed against the engine block and, like a suction cup, attracts the body very strongly. When the engine is running, oil passes through it and it adheres even more to the block. Thus, when the time has come for the next maintenance, you need to change this filter element, but it is not always possible to unscrew it by hand (sometimes it sticks so that the body wrinkles, but does not want to unscrew it). It was for such cases that a special key was invented.

I would also like to note that buy only original filter elements, otherwise a fake one can ruin your motor. Watch this video.

Key types

First, let’s talk about special keys with which you can unscrew the filter. The principle is simple. you need to put on the filter and unscrew:

  • Box key. It is a movable oval “half-piece” with teeth on one side. And a short protrusion that is aligned with the handle on the other.

As you understand, the moving part is retracted and thrown over the filter housing. And with a small protrusion, you kind of press down on the other side, thereby providing a very strong fastening.

Then we simply unscrew by the handle, a very simple and effective design. A big plus can be called the fact that it also fits simply, there is no round loop that needs to be tightened

  • Key to fit. This type is focused specifically on a specific oil filter, thrown on top and unscrewed. Indeed, often the body is made either with notches or resembles a nut. By the way, such options are recommended for plastic cases. The downside is that it is not universal.
  • Key head. It resembles the second type, only it is made in the form of a “head” thrown over from above. The disadvantages are that it is not always convenient (because there may be no space near the filter), and again only for one size, that is, it is not universal
  • The crab key. This is a universal type, on top there is a platform for a head or a knob, there are three legs that clamp the oil filter, and there are also three nuts (or gears) with which you can adjust these legs. Plus the fact that the design is universal, the disadvantages are expensive (from 500. 600r), and again it is not always convenient for them to crawl

It is worth noting that there are also special pullers, it is difficult to call them keys.!

Puller types

In fact, there are only two types of them and they work the same way:

  • Ribbon loop. Everything is just a handle, in which a slot is made and a loop is inserted there, they can be made of soft material (such as rubber), they can be made of hard material, but must bend (for example, a thin sheet of metal). It is thrown on top and tightened with the handle, then we simply unscrew the oil filter element
  • Loop from the chain. Everything is the same, only the loop is made of a chain, many write that this option is much stronger, because the first type (rubber or thin metal) can trivially break

Some masters say that it is the pullers that are the best option. but how in reality?

How to do it yourself

Oil filter wrench. you most likely won’t! But the puller can be made easily and quickly.

Basically, you only need to have a torn or old timing belt or a piece of bike chain.

Next, you need to slip the belt (or chain) into the spanner wrench (suitable for 17-19). We put the resulting loop on the oil filter, on the other side we twist it. After the loop has tightened, you can try to unscrew.

However, you can also make a special puller, such as in this video, see.

This concludes, I think my material was useful to you. Sincerely your AUTOBLOGGER

A simple key from the chain (made for fittings, etc.)

Hello everyone, I needed a wrench for fittings, pipes and other connections. Hastily assembled the necessary key from a chain, a piece of pipe and other rubbish. I didn’t count on anything, didn’t measure it out, everything by eye.

I spied the idea on YouTube, but I didn’t like all these threaded rods and stuff. I just have a loop on the chain that clings to the teeth. Such a chain can be thrown over a solid pipe and tightened the connection.

Perfectly hooks on various fittings, corners and other connections. Also perfectly at a certain radius of the chain, the wrench grabs the pipe! The work of the instrument is also interesting in that a certain “ratchet” effect is observed. In one direction, the loop tightens and holds the fitting, and in the other direction, the loop loosens and releases the part.

If you are interested in the homemade product, I propose to study it in more detail.!

Materials and tools used by the author:

List of materials:. a piece of pipe;. a steel plate;. a piece of bicycle chain;. a nail (I have a weaving).

Step one. Preparation of parts I cut off a piece of steel pipe, chose the length by eye. If the lever is too small, you can always insert something longer into the pipe. From the nail, I bent a loop, it is then welded to the end of the chain. Carved a steel plate, teeth will be cut in it.

Step three. The wrench is ready, it rotates pipes perfectly, various fittings, both plastic and metal, are satisfied with the wrench. To work, you need a little experience, there are many tricks, how you can grab a fitting or a pipe, you need to select the optimal loop length, I realized this from the first few minutes.

This completes the project, I hope you liked the homemade product, and you found useful thoughts for yourself. Good luck and creative inspiration if you decide to do this again. Do not forget to share your ideas and homemade products with us!

Do-it-yourself universal wrench from a chain and bolt

Dear visitors of the site “Samodelkin friend” from the presented material, you will learn how to independently make a universal wrench from a bicycle chain, a bolt and three nuts with your own hands. Presented step by step photos of the assembly of the key and so off we go. Many of you have probably encountered such a problem. when the edges on the unscrewed nut or bolt are a little knocked down and a regular wrench is simply scrolled without performing its function. This can be solved with the help of a homemade chain wrench working in compression, that is, the harder on the handle of the key, the more the chain will be clamped and thereby unscrew any nut or bolt, even the most eaten.

To make a universal wrench, you need a piece of bike chain, two nuts and a bolt. We wrap the nuts on the bolt and weld a section of the chain to them in such a way that a grip is obtained and welded to the other side of the nuts. Next, we put the chain on that nut or bolt that needs to be unscrewed and tighten the bolt, thereby tensioning the chain, everything can be unscrewed)

  • bicycle chain
  • nut 2 pcs
  • bolt
  • welding inverter
  • angle grinder (angle grinder)

DIY step-by-step instructions for assembling a universal key.

And so, the necessary parts for assembling the key. Two nuts are screwed onto the bolt. We measure the chain, namely how much is needed from nut to nut. We make a mark in the place where the chain should be riveted. We clamp the chain in a vice and cut the rivets with an angle grinder. We knock out the rivets. Next, the chain is welded first to one nut. Then it is stretched and welded on the other side of the nut. The scale and excess metal is removed using an angle grinder (angle grinder). After that, unscrew the bolt and loosen the chain to the required diameter. We insert the nut and tighten the bolt along the thread, thereby tightening the chain and clamping the resulting connection. Testing the key in action. We fix the passed material by watching the video. Happy viewing)

Preparation of the working part of the future master wrench

For further work, you will need a nut with high sides and with an M10 thread. It must be clamped in a vice so that the ends of the chain segment are located between the nut and the jaws (on both sides). The chain itself, prepared earlier, will be hanging from below.

It remains to weld the chain to the outer sides of the nut on both sides. In order not to damage the threads during welding, a suitable screw should be screwed into it. This will also prevent the nut from deformation due to the high temperature and pressure of the vice.

As for the welds, they must be of high quality, because they will have the main load while working with a key. As for the nut, the higher its sides are, the more reliable the tool will be.

Where can a similar master key be used?

Such a tool can be used in many jobs. If the chain length allows, it can be used to unscrew the oil filter in the car. And in general, it is convenient to use it in hard-to-reach places where it is not possible to work with a gas or adjustable wrench.

There is another option for making such a tool, where only one side of the chain is welded to the nut. At the opposite end of the nut, a hook is welded to which the chain will cling. In this case, a longer chain is used here. This allows you to adjust the diameter of the circle depending on the need.

But even the simplest version of the universal tool, considered today, allows you to perform various jobs that are inaccessible to a conventional wrench. And you can start checking the functionality of the device from the same bike frame from which the chain was removed. For example, you can try to unscrew the pedal carriage nut.

Interestingly, we even managed to tighten the carriage nut a little, despite the fact that the bike had been lying in the damp attic for a long time.

Another advantage of the key

Sometimes it is impossible to unscrew the plastic parts, for example, when replacing the water filter element. It is clear that the gas wrench is clearly not an assistant here. the pressure will simply crush the plastic. But with our device, this can be done due to the uniform distribution of pressure along the entire circumference of the plastic cover.

In general, such a tool is very easy to use. At the same time, even small nuts can be unscrewed with it. But to unscrew larger, and especially stuck parts, the homemade key will have to be strengthened, made more powerful.

Working with a chain, separating the required length

First you need to remove the chain from the frame. You don’t have to saw through the bike fork to do this, as some might think. Everything is much easier. The first step is to find the lock that is on each chain. Then, using a regular screwdriver, remove the fixing bracket from it, remove the link plate and knock out the pins with a dowel or center punch.

If the chain is too rusty and you cannot pull out the bracket, you can treat the lock with any rust remover. Best of all in such situations “WD-40” works, although other formulations are quite helpful. If the master has enough time (and under the current conditions of self-isolation it is quite a lot), you can fill the chain with ordinary diesel fuel and leave it for 4–5 hours. Then it will be easy to unhook the lock.

Homemade bicycle chain universal tool

The editorial staff of Homius continues the series of publications with the hashtag #Beschedoma, in which it acquaints the esteemed reader with useful activities that help pass the time during a period of prolonged self-isolation. And today we are talking about making a very useful universal wrench for various nuts, which can be made at no extra cost with your own hands from a piece of an old bicycle chain. And his version of such a homemade product is offered by the author of the YouTube channel Timofey, who relatively recently began to share his ideas on the network.

What is required to make a useful homemade product

Surely many Russians who are on self-isolation have already gone through the closets and even garages, in search of material for various homemade products. This means that the time has come to get into more inaccessible places, for example, in the attic. Most often, this is where the owners store trash, which can be used to good use. For example, an old bicycle chain can be used to make a great attachment. With her, certain actions have to be performed.

Tool handle, how to fix it

The screw handle can be made of wood. Even an old broken file handle will do. To fix it, it must be drilled. It is better to use a drill of a slightly smaller diameter, for example, by 9. Next, you need to dilute a little epoxy glue and coat the hole in the wood inside. Then, after 5 minutes, you can screw the clamping pin into the wooden handle as far as possible, and then leave the finished tool for a few hours. The layer of epoxy glue inside will be as thin as possible, which will lead to it drying very quickly. This means that in 3-4 hours the key will be completely ready.
