Distinguish the clock calipers and the digital calipers

The caliper is an item that is widely used today. Thanks to its distinctive features, it helps users to increase productivity, save time. The caliper is a product used to measure the outside diameter, inner diameter, the depth of shaped details accurate cylindrical, hollow, box-shaped cylinder. Currently, this device is widely used to help users work quickly and efficiently. However, many people still have confusion between two kinds of calipers because both types of them have watch faces.

So what’s the difference between a clock caliper and a digital caliper? When using them, what should you keep in mind? Although there are many types of calipers, most of them have the same characteristics. Therefore, in this article, I show you the difference between these two types of calipers and general notes when using them. Let’s find out in this article right now.

Compare the clock caliper and the digital caliper

Calipers have many product lines of different brands depending on the size and function of each type. However, mainly, calipers are still divided into three main types: electronic calipers, clock calipers, and mechanical calipers. Here, the products which people choose to use rather than the digital caliper and the clock caliper because of their unique handy features. So why they are more popular on the market today, let’s find out now.

Clock calipers

The working principle of clock calipers is that the inside of the meter’s dial has a mechanical system that makes up the rack and pinion. The measurement results are shown when the internal gear is designed to move the shaft to make the clock hand rotate in 0.01mm or 0.001-inch steps. To be able to read the measurement value, we understand the importance of the main body of the caliper and the second part from the measurement shown on the dial. The advantage of the clock caliper is that it works independently of the battery to operate and is capable of working in wet conditions.

However, the clock caliper still has some disadvantages that need to be improved. For instance, the racks and gears in the clock caliper are quite delicate, so if there is a mechanical error, the adjustment is quite complicated and challenging, this makes it difficult for the calibration process. Besides, it is not easy to read the results on it.

Digital calipers

The electronic calipers have a digital screen; the measurement value is displayed right on the screen, so the measurement is more comfortable for the user. Another feature of the digital calipers is the ability to provide measurement systems in both metric and inch units or convert date measurements on the caliper’s screen, which saves time and reduces many troubles when having to change the measurement unit.

So how can the digital caliper display the measurements correctly right on the screen? The answer is hidden below the ruler and screen slider. The bottom of the caliper is engraved with a copper band with a specific design. The digital display board is designed with a control chip. The individual copper wires and circuit boards act as a circuit system. The entire system acts as a capacitor network. The indicators shown on the screen by seeing changes in capacitance, such as moving the ruler along the meter range, are due to the specific design that allows detecting small changes in capacitance to provide measured values ​​for accurate reading results.

General notes when using electronic calipers

Although they have differences in characteristics, such properties, besides that, they still have the rules, the general notes when used the same. Here are the signs to use that you need to remember:

  • Do not use a caliper to measure when an object is rotating
  • Do not measure rough surfaces
  • Do not force the two measuring pins forcefully on the purpose
  • It is necessary to restrict the removal of the ruler from the measuring object before reading the measurement value.
  • The measuring tape must be placed in the correct position in the box. Do not place the caliper on top of other tools
  • Always keep the ruler free of dirt on the caliper, especially the grinding dust, cast iron, and irrigation solution
  • Every day, at the end of the shift, clean the caliper with a clean cloth and an open oil
  • The caliper should be stored in a dry place, away from moisture, and regularly checked for accurate calibration. It can be cleaned with oil, but only a little because of too much lead to oil buildup that can easily cause dirt.
  • Before measuring objects, first of all, you need to press ON to start the ruler
  • Press the mm/inch button to select the desired unit system as you wish. Finally, press the ZERO button to set to zero.
  • Press ON / OFF to turn off the power when the caliper is not in use, remove the battery from the machine if it is not used for a long time.
  • For batteries, if the display is not standard (digits flashing or not even displayed), indicate that the battery is low. So you need to replace it with a new one.
  • In case of water entering the battery cover, open the lid immediately and blow into the battery cover at a temperature not exceeding 40 ° C until dry.

In conclusion

A digital caliper is a powerful tool for the job, and each type of caliper has different characteristics and uses. Therefore, you should learn them before using them. In this article, I have shown you some of the differences between the two types of clock calipers and digital calipers. Hopefully, they help you better understand the electronic calipers and know how to store them when you buy the best digital caliper for your job.

Forming and instructions for using the woodworking dust masks correctly

It knows that when working in hazardous and dusty environments, we must take reasonable precautions. If you must work in an environment with a lot of sawdust and wood dust, it is necessary to equip the best woodworking dust masks to ensure the health of workers. However, many people still do not know how to use and clean covers to preserve them.

Structure and operating principle of the dust mask for woodworking

structure-and-operating

Most workers using a gas mask, neglecting the critical step, which finds out the frame of products. If the employee works in an environment with low-level chemicals, less exposure time, you only need to search for a suitable one-filter dust mask. Also, you can use a cover that has two filters to protect better health. It leads to workers to choose the wrong type of respirator with their working environment causing respiratory diseases when used or causing waste.

  • Structure of the woodworking dust masks

Gas mask:

Currently, on the market, there are many types of high-quality protective covers being born, meeting high-quality standards.  That helps workers and engineers have more choices for themselves. But in general, the material of the respirator mask is made of two main types: Polycarbonate, Silicon.

The filter of gas mask:

The screen is considered to be the “soul” of the gas mask. Because this component contains activated carbon, occupying one of the essential tasks is to remove dirty air, which can cause discomfort and the shortness of breath for the users when inhaled.

If a worker works in a chemical industry workshop with a high concentration of dirt, lots of toxic gases, you need to use the gas masks equipped with two filters. Because of this, the new screen works well to protect maximum safety for your safety.

  • The working principle of the gas mask

Artificial respirators use a combination of a filter cartridge (filter) to remove gases, volatile organic compounds (VOCs), and other vapors from the air by adsorption and adsorption. A typical respirator filter is a metal or plastic container containing 25-40 grams of adsorbed particles such as activated carbon or certain resins. The life of a chemical filter varies based on other parameters, according to the carbon weight and molecular weight of the vapor and the transfer parameters, the concentration of water vapor in the air, the relative humidity of the sky, and respiration of respirator user. When the filter becomes saturated, or particles accumulate in it begins to restrict airflow, we have to change to a new filter battery. If concentrations of hazardous gases are immediately dangerous to life or health, the law requires that the use of any air purifier strictly monitor.

The purpose of the woodworking dust mask is to let the air be polluted or a variety of pollutants, remove a sufficient amount of these contaminants and then supply the air to the user. Use different filters for different working environments — the amount of air reaching the user through one or more screens for the user to breathe.

Instructions on how to use the mask correctly and how to store it

  • Instructions for using the cover properly

The respirator has two types of breathing valves: the valve that directs the air into the filter and the exhaust valve flows as a transport in a closed cycle. In case the air intake valve is open, toxic gas will enter the pipes, following the flow into the lungs in the nasal period. In the case of open exhaust valves, exhaled air, and tiny particles of water and when the carbon will attach to the filter material such as activated carbon. It is a fast corrosive material; the filtering function significantly reduce. Should choose the type of gas masks with valves to open quickly, durable, ensure tightness.

The filter is quickly saturated. Therefore, it must be replaced periodically depending on the type, storage conditions, time of contact with chemicals, use time, the density of chemicals, and toxic properties of compounds.

Just like the daily farm work, while spraying pesticides, when a little smell the smell of drugs while still wearing a mask, they must change immediately. Please refer to the table of instructions for using the respirator mask of the filter you buy to know precisely when to replace.

Activated carbon is the main ingredient in the filtration process. After that, it reinforces with appropriate chemicals depending on the environment of use; the toxins need to be filtered and can add a catalyst to coal. Active can absorb toxic gas. The filter has a pore, cavity structure to keep toxic vapors in contact with activated carbon. Next will appear the chemical reaction process in the screen; the impregnated chemicals convert poisonous gas into the fresh air. Clean air flows through the valves into your nose. Sometimes, to ensure adequate air supply, the filter also contains additional catalysts to make the process faster, more active than usual. So when the filter box has saturated, expired, cracked, dust making the breathing process difficult, they need to be replaced immediately.

  • Time to use the gas mask

Time to use respirator masks on average from 1-2 hours. It is time to ensure the cover works best.

The duration of use also stated in the Respirator Instruction Manual is intended for environments with a unique level of toxicity, as well as environments with high concentrations of toxic gases, high pressures, temperatures and humidity, and service life. The filter significantly reduces. The preservation and maintenance regime after use is also related to the service life of the filter box. In the same working position, the higher the amount of breathing air the person has, the shorter the filter’s life will be. When the screen opens, it will be discarded for a long time because the activated carbon no longer works.

  • How to store respirators:

For the gas mask to be durable and safe during use, users must know how to preserve it best. When choosing a gas mask, it should select the type of valve that opens easily, durable, ensuring tight. Due to the different working environments, depending on the type of cover will fit or not. If exposed to dense gases, heat, pressure, and humidity will cause the mask to degrade quickly.

Therefore, users should pay attention to maintenance masks regularly. Check to see if there are signs of cracking, difficulty breathing, or smell of chemicals; you need to change the cover urgently. Attention should be paid to the air passage; avoiding leakage will be very dangerous.

Besides, immediately after using the 3M respirator, inspect the filter. If it finds that the contact environment has a lot of harmful reading gases, the filter must be replaced immediately to ensure life. At the same time, each screen has its expiry date, so be careful to replace it.

In conclusion

The woodworking dust masks are a particular product to help avoid the harmful effects of toxic gas, so you need to pay attention to the structure and operation of the gas mask. Once you know the function of the parts, you will have more experience in buying the right cover for your needs.

Factors to be considered when buying a wood planer

The success of many woodworking projects lies in whether to buy a suitable and reliable wood planer. However, determining which wood planer is best to use is complicated and difficult for buyers. This is because different woodworking projects and specific needs will require different types of wood planers.

Understanding that, in this article, I will give some essential criteria that you need to consider when deciding to purchase a wood planer. Let’s find out.

Types of wood planer

On the market, there are many types of wood planers designed to perform different functions. In general, they are classified into two main classes – the hand wood planers and the electric wood planers.

Hand wood planers: Hand wood planers are mostly designed for small-scale manufacturing at small-scale workshops or home. It is the best wood planer for beginners. However, To make these planers work, the workman must use a sufficient amount of energy to push it forward and plan several times. That consumes the energy of the user.

Electric wood planers: As their name suggests, These planers are supplied with electrical power to operate. They are convenient and effective. And this planer is equipped with a powerful motor. This makes the planning process faster, more accurate and easier. So it is always recommended for heavy-duty work in large workshops as well as the best thickness planer.

However, this type of device is extremely diverse. You need to consider a lot of aspects before buying. For example, the motor and horsepower of the machine. Other factors to be considered include the cutting depth of the planer (the thickness of the blade in one turn), the flatness of the table surface (ensuring smooth work) and of course the width of the planing surface. (defines the width of the wood that can be cut)

About price

The cost of the planer varies depending on the device manufacturer and the quality of the tool. You should choose a planer that you can afford in limited resources at your disposal. Do not intend to get the cheapest machine or tool because the current cheap price can become very expensive later. That is easy to understand, Cheap device certainly its quality will not be as good as the expensive one. You will quickly have to bring in regular repairs. That leads to more costly when buying an expensive but quality one. In my opinion, Hand wood planer is the best wood planer for the money for you because it is quite cheap and quality. Besides, do not use an electric planer if you do not have easy access to electrical points.

 Efficient and convenient

Can the wood planer that you are planning to buy perform the tasks you set within your expected time frame? What does the final product look like? Here are some of the most important questions you need to ask yourself before buying a planer. Look carefully at the functions of each wood planer so you can purchase the best wood planer.

About safety

If you choose a planer, you must not forget that they are equipped with a cutter that runs at high speed. You must be alert to this exposure hazard. So you must ensure that the cutter reaches maximum speed before you start cutting and join smoothly and professionally with two hands. Keep your work area free of any obstacles. Moreover, Wear protective gear such as eyeglasses and protective clothing (avoid wearing gloves because it interferes with your planning process)

Chip direction

For maximum efficiency and flexibility, you need to buy a planer that offers options for left or right chip direction. This helps determine the dust bag or the location of the dust collector depending on the job. But where you don’t plan on using a dust tube or bag.  A good option is a model with a chip chute that you can remove easily.

The length of the cord

Longer cords will give you better access anywhere in your store. But its downside is, if you have to put the tool away or pack it in a car to work regularly, you need to coil that every time. Because the cord is too long, it will prevent the movement.

Horsepower of wood planer

In general, the more powerful the motor, the more accurate and efficient the planer. Most in-house woodworkers expect a 5 or 6-amp power planer. For heavier work, you can get the higher horsepower

Cutting depth, blades, and accessories

The cutting depth of the planer converts to the amount of wood that the blade will cut in one run. Carbide blades are generally recommended because it is more durable than HSS. The longer and bigger the fence, the better it controls. Many angled guides, cutter heads, dust control functions, and adapters are also things you need to research.

In conclusion

I have mentioned a few criteria that you need to consider when purchasing a quality wood planer. Hopefully,  this article will be useful to you. And thanks for reading.

Antique Buffet: Incorporating Modern + Reclaimed Pieces

Uh, yeah….
Tell me that’s not the yummiest buffet you’ve ever seen! When my dear friend Bri snagged this piece for her home, I instantly fell in furniture-love! The lines! The detailing! The paint! Plus, her use of this buffet as a media center is spot on. I wanted to share how she tastefully incorporated this antique piece in with more modern surroundings…although, I don’t know if I’d be able to concentrate on the TV with that beauty in front of me!
I absolutely dig this idea. The buffet contains all of her wires, boxes, consoles etc. and the TV is seamlessly mounted in to the wall (time well spent!). The buffet adds so much interest and elegance to this living space. Bri actually was shopping a local antique strip when she saw this unfinished buffet come off a truck. Even in it’s plain-jane state, she saw potential! Some chalk paint and expert distressing was all this piece took…now, it’s one of the centerpieces in her home!
