DIY Bike Chain Key

Is it worth repairing a bike chain on the road at all??

DIY Bike Chain Key

It is best NOT to repair the chain on the road. Repairing a chain is one of the dirtiest jobs. If you have new clothes, then after repairing the chain, you can most likely say goodbye to it. Probably the best solution would be to call a taxi or attach your bike to the bike lock and go home by public transport. you will come back in your old clothes and calmly repair the chain.

How to start repairing a bicycle chain.

Let’s say you have already changed into old clothes and are ready to get to work. To make it easier for you to inspect the chain. Turn the bike over.

Inspect the two broken ends of the chain: one end (and possibly two) is damaged and needs to be replaced. You will need to remove two chain links from the damaged end of the chain. Why do you need to remove two links, and not one. you might ask? Since the chain consists of two types of links, if you remove only one link, you will not be able to connect two links of the same type.

At the point where the chain needs to be opened, place it in the groove of the chain mounting tool (see photo). The same procedure applies when repairing a worn chain.

How to repair a bicycle chain

With proper preparation, repairing a bicycle chain on the road is NOT more difficult than sticking a bicycle tube.

What you need to repair your bike chain.

To repair a damaged bike chain, you only need a chain fitting tool. It is compact and usually found in many multi-functional bike repair tools. Perhaps a similar tool is included in one of your multifunctional tools and you simply did not know what it was for.!

At home, repairing a bicycle chain can be done with a hammer and pliers, but you can’t take them with you on the road. When traveling, the chain only needs to be repaired with a lightweight chain mounting tool.

Adjust the link you just installed.

Once the pin is in place, the attached link will not bend well. They move the link forward and back (see photo) until it becomes well bent so that it can safely pass around the gears.

Look at your hands. now you can feel like a real bike mechanic.

How a bicycle chain works?

The chain links are connected to each other using a steel pin. To remove or install a link, remove or hammer in the pin using a chain tool (or hammer). To repair the chain, you simply need to remove the damaged links and connect the ends of the chain to the undamaged links. On bikes with classic derailleurs, the chain is slightly larger than it needs to work, so you can painlessly remove a few links. Single-speed bikes and bicycles with planetary link hubs, which can be removed painlessly, most likely will NOT. So in this case, you will have to bring a new chain or an old chain with which you can remove the missing links.

Joining links.

Before connecting both ends of the chain, put it back on the sprockets. It will be great if your friend can help you hold the two ends of the chain in position while you connect them.

Using the chain fitting tool, insert the pin back into place (see photo). This is the hardest part of the job as you need to keep the tool in line with the pin. If you are just installing a new chain, then most chains come with a special link (lock) that allows you to remove and install the chain without having to remove the pins.

Disconnecting a chain with and without a chain installer.

To start pushing the pin out of the chain, turn on the chain installer (see photo). Try to align here on the chain mounting tool with the pin on the chain (sometimes it slips a little).

DO NOT push the pin all the way in. push it just enough to disconnect the circuit (see photo). The remaining piece of pin must be left in the chain so that it can be easily pushed through later.

If you do not have a tool to install the chain, then you will have to find a piece of wood and drill a small hole in it. Place the pin you want to remove over the drilled hole. Find a Small Mounting Screw about the same size as the pin and use it as a stud. Hit it with a hammer to knock the pin out of the chain to the required distance. Beat him very carefully so as not to knock him completely out of the chain.

The chain breaks as usual?

More often than not, the chain breaks when you pedal at full power and simultaneously shift gears on the front derailleur. Other causes of chain breakdowns are very rare, one in a million at best. You only get a chance to meet them if you bike a lot. For example, once a nail flew out from under my front wheel, which hit right into the chain and hit the sprocket. Who would have thought that this could happen?

DIY universal wrench from a chain and a 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 key assembly and so off we go. Many of you have probably encountered such a problem. When the edges on the unscrewed nut or bolts are a little knocked off and a regular wrench is simply scrolled NOT performing its function. This can be solved with the help of a homemade chain wrench working in compression, that is, the stronger on the handle of the key, the stronger the chain will be clamped and thus unscrew any even the most eaten nut or bolt.

To make a universal wrench, you need a piece of bicycle chain, two nuts and a bolt. Screwing the nuts onto the bolt and weld a piece of the chain to them in such a way that you get delight and weld it to the other side of the nuts. Next, we put the chain on that nut or bolt, which must be unscrewed and tightened, thus tensioning the chain occurs, everything can be unscrewed)

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. Measuring the chain, namely how much is needed from nut to nut. We make a mark in the place where the chain should be riveted. Clamp the chain in a vice and cut off the rivets with a 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 with a grinder (grinder). Then we unscrew the bolt and weaken 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. Securing the passed material by viewing.

How to protect your car from theft

According to statistics, every 10 seconds a car is stolen in the world. Moreover, more than half of the stolen cars have never been found. Isn’t it better to secure your car by protecting yourself from unnecessary stress, loss of time, nerves and energy? What to do? How to protect your iron horse and sleep well? We will tell you about all this today.

The most popular car anti-theft systems

It is believed that anti-theft is almost the best antidepressant and sleeping pills for a motorist. Anti-theft agents are different, with their own advantages and disadvantages.

Mechanical blocker. it allows you to lock the car with a separate key, and not allowing the attacker to easily enter your iron horse from under your nose. A mechanical lock can be installed not only on the steering wheel, but also on the pedals, on the gearbox and even on the hood. The hood lock will protect the anti-theft devices that are located under the hood (alarms, sensors and lock relays).

An alarm is the most common way to protect a car from theft, although it is NOT the most effective. But without alarm, cars are stolen more often than those that are equipped with it. To maximize the safety of your car, you need to choose a high-quality alarm with a special sound signal. It is best to install an alarm with feedback: in this case, you will receive a message on the key fob that enemy forces have approached the car. Well, if a motion sensor is connected to the alarm, you can easily turn off the engine in the event of an unauthorized start.

An immobilizer is a device that is capable of breaking important circuits in the ignition system. It can only be turned on and off by the vehicle owner. The good thing about the immobilizer is that even if the car thieves somehow get the original car key, it will still NOT be able to steal it, since a special electronic code key is required to turn on the immobilizer.

Satellite system. it is designed to detect a stolen vehicle. This greatly simplifies the search for a car and minimizes the risk of theft.

Best of all, of course, Reinforce your horse with all anti-theft systems, especially if your car is very expensive.

Anti-theft Precautions

To minimize and NOT provoke intruders to steal a car, you should take precautions:

  • Never leave documents, bags, wallets, equipment or other valuables in the car. Often these items are the targets of theft;
  • Equip the car with anti-theft markings, because it is much more difficult to sell such a car or its parts, or rather, almost impossible;
  • Under no circumstances do NOT tell anyone exactly how you protected your car;
  • Never leave the ignition key in the car, even for a second. The car thieves are very quick and dexterous: before you get out of the car, it will already leave in an unknown direction;
  • Insure your car in case of theft. this can be the only consolation in the future that will help you survive the loss of your iron friend;
  • To prevent the wheels from being removed from the car, put at least one bolt with a non-standard head. this will complicate the thief’s life and, possibly, save the car from losing wheels;
  • If you do NOT intend to use the car for a long time, prepare the car for parking: Drain the gasoline, battery with them, cover it with a cover. Do not forget to shake off the snow in winter so that the car does NOT give the impression of being abandoned;
  • Didn’t become the car near the cinema, concert halls, stadiums, theaters, etc. In this case, the Attacker will know exactly how much time he has to hijack and will act within THIS time frame. Put the car a little further away from such places of entertainment;
  • In the parking lot in the yard, choose a well-lit and passable place, because in a dark deserted corner of the yard it will be much easier for a thief to do his dirty work.

BEHIND THE BARANK. How to do it yourself

Oil filter wrench. you most likely DO NOT! 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 move 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 Unscrew.

However, you can also make a special puller, such as this one. We look.

The oil filter is not easy to remove, even if it is tightened by hand. It has a rubber gasket, which is tightly pressed against the engine block and, like a suction cup, attracts the body very strongly.

Homemade FRIEND

Key types

To begin with, let’s talk about Special keys, with which you can Unscrew the filter. The principle is simple. you need to put it on the filter and Unscrew:

  • Box key. It is a movable oval “half-piece” with teeth on one side. And a short protrusion 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 seem to press down on the other side, thereby providing a very strong fastening.

Then just unscrew by the handle, a very simple and effective design. A big plus can be called the fact that it is also simply thrown over, there is a 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 He 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 wrench, 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?

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 not be convenient only because there may be no room, and it is banal that you are NOT Oden’s head (or “cape”), and if I wear it, it will be uncomfortable (or practically NOT possible).

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

The oil filter is not easy to remove, even if it is tightened by hand. It has a rubber gasket that is tightly pressed against the engine block and, like a suction cup, attracts the body very strongly. When the engine is running, oil flows 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 fake ones can ruin your motor. Look at this.

The adjusting screw and what it can be made of

A long bolt or stud can be used as an adjusting clamp screw. Their length should be such that when they are fully screwed in (chain tension), at least 5 cm remains on the reverse side of the nut.This is necessary to be able to fasten the handle.

Provided that an ordinary bolt is used as a clamping screw, it is necessary to cut off its head. It will NOT be needed for further work. This can be done using an angle grinder (grinder) with a cutting disc.

Homemade universal bike chain 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 will help reduce the time during the period of protracted self-isolation. And today we will talk 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.

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 with a slightly smaller diameter, for example, 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, 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.

What is required to make useful homemade products

Surely many Russians who are on self-isolation have already taken pantries 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 their 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.

Separating the desired section from the whole chain

The entire length of the chain is not needed for a homemade universal wrench, so it is necessary to separate certain sections. All work can be done with a dowel or center punch and a conventional hammer. Although many craftsmen, and not wanting to waste extra time, advise using a grinder. This method is quite acceptable, because what the edges of the chain will be, for the homemade product described today, it does not matter.

There should be 13-15 links connected with the same number of coupling webs. In fact, a larger key is NOT required for a simple key. Perhaps in the future, the home master will make other keys, the chain on which will be longer or shorter, but today the most average option is being considered, so that its essence of work is clear.

Where can a similar master key be used?

This 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. A hook is welded on the opposite end of the nut, the chain will cling to the yak. In this case, a longer chain is used here. This allows the diameter of the circle to be adjusted as needed.

But even the simplest version of the universal tool, Considered today, allows you to perform various jobs that are usually not available with a key. 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 Unscrewing the pedal carriage nut.

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

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 fork of your bike to do this, as some might think. Everything is much easier. The first step is to find a lock, which is on each chain. Then, using a conventional 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 rusted and you cannot pull out the bracket, you can process the lock with any rust remover. WD-40 works best in such situations, although other formulations are quite helpful. If there is enough time in the master (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.

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 our devices can do this 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.

Preparation of the working part of the future master key

Working humidity will require a nut with high sides and 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.

Remains Weld the chain to the outer sides of the nut on both sides. In order not to damage the threads during a quarrel, a suitable bolt 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 welded seams, they must be of high quality, because they will have the main load during the key operation. As for the nut, the higher its sides are, the more reliable the tool will be.
