How does a hot glue gun work?

Glue guns have recently become very popular not only in construction, but also in everyday life. Owners of new tools have long understood that it is much easier to glue and use this type of glue is much more effective even in terms of savings. It glues literally instantly and adheres to almost every surface. It is used by retailers in shops, loaders in warehouses, builders during repairs and even by children to make handicrafts. Such a tool is really an indispensable assistant to the modern man and, having bought this device, a lot when working with it will be nothing. But the factor of the right choice here is very high, there are many varieties of new tools and each has its own features. We read this material to buy the right glue gun and never feel the discomfort of its use.

What kind of tool is it and how does it work?

We will now without rush get into the principle of the glue gun and gradually move on to questions of choice. After reading through to the end, each reader will be a professional in the subject, which is our only and main task. So, first of all, let’s consider the principle of an ingenious device. If we look at the appearance of any model, we will see the resemblance to the weapon, which was included in its name. It is also clear that they can be glued. This process is quite ordinary, there is special glue ammo (we will tell you more about them a little bit later), which are loaded into our glue gun. 

When the device is switched on, the cartridges start heating up to a temperature above 100 degrees and melt. By pulling the trigger, we can gradually squeeze out the hot adhesive flow and apply it to the surface of the bonded parts. The main advantage of this glue over analogues is the rapid cooling of the molten glue. After literally 10 minutes you can already use the glued items, and small drops cool down even in seconds. Another positive feature of glue from a glue gun is the ability to stick to anything, but more about this further. And before we start the next item, let us enlighten you about other names of our wonderful device. Besides the name “glue gun”, it is very often called “hot gun”, “glue gun”, “hot glue gun” and even “glue gun”, all of which we will try to use for better memorization. And the above mentioned completely emphasizes the essence of the tool, because it is a device that allows you to work with hot glue through high temperature.

What materials can be glued with a thermal glue gun?

There is not much to say about materials – you can glue almost everything. With the glue gun you can glue wood, plastic, rubber, glass, metals (it is better to heat them up with a hair dryer before work, because of the high thermal conductivity), fabric, foam, ceramics, cardboard, paper, flowers, etc. The only thing that some types of plastic and textiles are reluctant to bind, only such exceptions are rare. 

Similarly, it is not possible to glue something to plaster and concrete. It is necessary to understand at once that rods with glue are of different kinds and under different materials they are different, but the classical colorless rod can glue all listed. Now, perhaps, it is clear what such a huge popularity of this tool is. And we do not think that such glue was invented only recently, it was before, but a handy tool has been recreated only now.

Let’s begin the choice. Professional or household tool.

We have already figured out what a glue gun is, now it is time to choose a new tool. And the first criterion for selection is to choose between professional and household types. But it’s not that simple, the classification is very delicate. According to one principle, professional hot glue guns are only tools with automatic feed rods. According to other rules, hand tools can also be part of the professional tool group. And we will take the side here, because the automatic core feed is used on expensive thermal glue guns in factory conditions. 

There, the glue gun operates for 24 hours without switching off, and the importance of not constantly pressing the lever is a very important factor to improve the performance and durability of the instrument. For construction work, even professional hot guns have a mechanical glue supply. Therefore, automatic glue dispensers will be discarded immediately, because even in a professional shop it is difficult to buy such devices, they are already made especially for factory tools for conveyors. We are interested in a simpler tool, but it can also be referred to the professional category (although in reality it refers to semi-professional products).

How to choose boxing shoes

High-quality boxing shoes give the athlete stability in the ring, confidence in movements, and also protect the foot and lower leg from injuries. Boxing shoes are very similar to wrestling shoes, but nevertheless, they have some differences in details and designs. To get the expected result from boxing shoes, you need to consider some of the important nuances when choosing them.

Materials

According to ringside24.com website, shoes are made from synthetic materials, as well as light leather or suede. Breathability of shoes is directly related to the comfort of the athlete. Non-breathing models, even the ones from genuine leather, cannot provide the necessary air circulation. Therefore, some manufacturers use a mesh as a material to eliminate the feeling of heaviness in the feet, which can occur due to the accumulation of sweat.

Sole

The sole of the boxing shoes is textured. Its most common pattern is the Christmas tree. This technology of the sole gives the effect of anti-slip and provides the dynamics of the boxer’s movements in the ring, as well as traction back and forth during lunges and deviations.

Brands

One of the well-known manufacturers of sports shoes – Adidas – actively uses modern technology to improve ventilation of shoes and traction of the sole with the surface. Special ventilation ducts remove moisture and lower the temperature inside the shoe, providing optimal control over the humidity level. The sole is made of a special rubber compound, which is characterized by wear resistance and excellent traction, even with a small weight of the athlete.

The famous British brand Lonsdale is also loved by many world-class athletes for its outstanding design and soft, durable sole that combines several types of rubber. Boxing shoes of this company sit well on the foot, hold the foot tight and fix the heel. The upper part is made of synthetic material that allows the foot to “breathe”. Toe and heel are made of high quality leather or suede.

Green Hill is another worthy notice manufacturer of shoes for boxing and other martial arts. The quality of the shoes meets the requirements of international organizations: a durable non-slip sole, light weight, a comfortable microclimate inside, decent protection for the athlete’s legs and feet. The models of this company are wear-resistant, while their price remains affordable. In 2004, Green Hill was recognized by the International Amateur Boxing Organization for its high quality boxing equipment.

Ankle height

Boxers are most at risk for ankle damage. Properly selected boxing shoes perform the function of protecting the feet and legs from injuries, they reliably fix the athlete’s ankle with laces and Velcro.

Boxing shoes can be different in height. Depending on the style of boxing, the following types are distinguished:

High – the shaft reaches 1/3 of the leg, up to 25 cm. They are warmer and heavier than low models. The high shaft additionally supports the calf and lower leg, reliably fixes the ankle, protecting against injuries during the fight. But you need to choose boxing shoes of such a model very carefully. If the shoes are chosen incorrectly, then there may be a violation of blood circulation in the athlete’s legs. This will cause not only discomfort during the fight, but will also harm the health of the boxer.

Middle – the shaft is from 15 to 20 cm high. These boxing shoes are an intermediate option. They fix the ankle, but the leg, at the same time, remains mobile. This model is suitable for those who are not ready to sacrifice security and want to minimize the risk of injury.

Low – the shaft is from 10 to 15 cm high. This is the lightest model that does not overload the leg with excess weight and does not limit its mobility. Such boxing shoes, first of all, protect the foot from dislocations and unsuccessful touchdowns. They are more suitable for athletes who prefer the technique of quick movement in the ring.

It is best to have several pairs of shoes, as professional athletes do, because each of the models is designed for certain conditions and combat techniques.

Size matters

When choosing boxing shoes, you need to pay attention to the completeness of the pad and the length of the insole. With the wrong choice of size, the entire set of technologies laid down by the manufacturer will not make any sense. Such shoes not only will not bring the desired result, but can also cause discomfort for its owner. Boxing shoes should fit snugly to the foot, securely fix it, but at the same time not hamper the athlete’s movements.

Shoes should be made of quality materials, meet the conditions and goals of their use, protect from injuries, be comfortable and just nice for the athlete. Only then the boxer will be able to concentrate as much as possible on the fight and the opponent, without being distracted by the discomfort in his shoes.

How to choose a Stabilizer for Smartphone

You can choose any metal for the parts, since weight gain is only beneficial. The main thing is to ensure the rigidity of the structure. Weights should not swing the horizontal bar, and the vertical bar should provide sufficient resistance to bending and torsion in order to avoid the occurrence of spurious damped oscillations.

When testing the layout, I used a thin-walled steel channel as a vertical bar which just had low torsion resistance, which led to the occurrence of spurious camera vibrations in the horizontal plane.

For reliable fastening of the handles, holes were drilled in them, into which metal threaded bushings were glued using epoxy glue.

Here is the inertial stabilizer with the camera installed in assembled form.

In order not to take the weights on a trip, it was decided to replace them with rigid 250 gram PET bottles filled with sand. The specific gravity of sand in the reference book is about 2.7gr / cm³. In this case, the mass of each of the weights should be equal to about 700g. Such a mass and its distribution map should provide stabilization no worse than when using a full-sized stabilizer.

I must say that during freefly movi review with river sand, it turned out that the weight of the filled bottles reached only 1.2 kg. However, due to the shape of the bottles, the quality of stabilization was not worse than the one provided by a full-size device.

To ensure the necessary rigidity of the structure, it is advisable to choose the most dense thick-walled bottles, with caps with a diameter of at least 40 mm. It should be noted that the bottle labels made of heat-shrink film give the bottles extra rigidity. Such labels should not be removed.

Washers covering covers on both sides should be as large as possible.

In order for the screw fixing the square to the horizontal bar of the stabilizer not to scroll in the axle box while tightening the lamb, the contact surfaces of the axle box and screw were tinned, and the screw was tightened in the axle box in a heated state.

The increase in the number of parts of this unit is due to the absence of large washers with a small diameter of the inner hole.

And this is the “beach version” of the stabilizer when assembled.

In order that the stabilizer can be installed on a horizontal surface between shootings, a square “window ” is added to the mount of one of the bottles.

The disadvantage of this stabilizer is that it attracts excessive attention from others. The attempt to put black socks on the bottles did not give much effect. Apparently, the unusual shape of the device really does attract much attention.

Attention! In all the drawings, conventional and roving washers are not shown, which are preferably used when assembling and locking the fasteners. Lock screws with countersunk heads can be nitro paint or nail polish.

The size ratio of the inertial stabilizer

When the camera deviates from the horizontal axis, the videographer is forced to fix the stabilizer handle in his hand. The moment of force transmitted to the person’s hand is directly proportional to the length of the vertical bar and the weight of the camera, and inversely proportional to the diameter of the handle. Therefore, the convenience of controlling the camera depends on the diameter of the handle. To improve tactile sensations about the position of the handle in the hand, it is useful to make small concentric recesses on it.

The thinner the handle, the harder it is to stabilize the steadicos during acceleration, but the thicker the handle, the weaker the tactile sense of the horizon.

Another compromise is the choice between the size and weight parameters of the design and the quality of stabilization. The longer the horizontal bar and the heavier the weights at its ends, the higher the quality of stabilization. However, with an increase in the length of the horizontal bar, its end may fall into the field of view of the lens, and an increase in weight makes carrying equipment uncomfortable. I do not recommend increasing the weight of the equipped stabilizer to more than 2.5 kg, and it is better to adjust the size limit to your favorite camera case.

Adjustment of the inertial image stabilizer for the camera

If you use weights, the position of the center of gravity of which cannot be changed (as in the photo), you can adjust the horizon by turning the vertical bar a small angle in its mount. Before adjustment, one of the screws is released, and the second one is not completely tightened. After that, the bar is set to the desired position, and both screws are tightened.

If the camera does not have an electronic level indicator, then an external bubble level can be used to adjust the horizontal position of the camera.

If you refuse to install a quick-detachable platform, and use a standard photo screw, then such a stabilizer can be made in just a couple of hours.

Here is the idea of ​​how you can raise the photo screw from the flash above the horizontal bar.


How to use an inertial stabilizer

As it turned out, using an inertial stabilizer is much easier than traditional steadicam. The rigid inertial stabilizer is always instantly ready for operation, due to the absence of damped oscillations inherent to the pendulum type steadicam.

When picking up speed, it’s enough to firmly squeeze the handle of the device and loosen the grip as soon as the speed stabilizes and the trajectory becomes straight.

The weight of the balancing structure in the hand makes it easy to feel the position of the camera relative to the horizon through tactile sensations. To improve tactile sensations, the handle is removed from the center of gravity of the system at a greater distance than in professional video cameras.

The disadvantages of the inertial stabilizer of the presented design

The main disadvantage of this homemade device is the significant weight that you have to hold in one hand when shooting and carry on the shoulder during transportation. It’s true though that steadicams of other types also have these shortcomings.

The use of a stabilizer for special effects

If you install one of the stabilizer handles at the camera level and remove the weights, you can (when shooting with your hands) create the special effect of “swing” or “ship pitching”.

In order for the loops intended for fastening the belt not to interfere with sound recording during rotation or sudden movement of the camera, they can be fixed with a clerical gum.

How to Select a Refrigerator

What size fridge should I get?

The answer is: It depends on the size of your fridge. The more you use, the more the fridge will degrade, and the more expensive it will be. But the reasons for this are complicated, so I don’t really have a very straightforward answer.

If you don’t cook on a regular basis, and you want the best possible performance in a smaller fridge, it makes sense to get a larger fridge. Because of the extra refrigerant that the smaller models use, your food will last longer.

Roof closets – 55″ x 55″

Compact 46″ x 46″

Mid-sized 52″ x 52″

Bigger 56″ x 56″

… Are there any other advantages of a 60″ x 60″ fridge?

A big 60″ x 60″ fridge should be high enough to keep milk bottles from spilling, a durable barrier that blocks any debris from getting in and turning your fridge into an actual tortoise cage, and to bring all your milk. These things aren’t available unless you

This varies by where you are located. Most of the biggest supermarkets in the UK will have a selection of sizes available. If not, check with the shop’s fridge specialist (most have large sections dedicated to cheese) and ask what size fridge they offer.

General fridge size recommendations

Remember that just because a fridge has a ‘large’ specification does not mean it is large. The guide above is simply a guide to help you see what sizes are available in some supermarkets in your area, and which would be good for general use.

How do you read a refrigerator-size?

What sorts of things are read that are found on a refrigerator-size — things like, “Cabinet, coat closet, 4-drawer laundry-room, galley, pantry, living room, sleeping quarters.”

A refrigerator-size refrigerator doesn’t read anything about what might be in a full-size kitchen or a house of a couple of hundred people. It doesn’t read anything about, “Is there a saloon?” It doesn’t read about, “Is there a bordello?”

What is the standard opening for a refrigerator?

The very first refrigerators were installed in 1924. Today the door to the refrigerator is always open and you can see if the internal temperature is below a preset setpoint. So what should I do when I see a refrigerator that isn’t operating properly? This happens because the fuel or coolant in the refrigerator is leaking out of the upper sides of the unit. A common cause for this is when the equipment is in storage (the food is not being cooked on). If this happens, open the door.

Think of it as being like an elevator. In fact, the door on the lower right in this image looks like it’s locked. So when we want to open the door, we pull it off of the frame of the refrigerator and rotate it into the unlocked position. Once unlocked, we can then push the drawer onto the freezer door and take a peek inside.

The front door (left), rear door (middle), and the front door of the freezer.

With fresh food and water, these appliances quickly generate about 300 liters of the refrigerator’s contents per hour (assuming these items are all made of what it takes to produce 100kg of the final product). This is about 1.5 cubic meters of unprocessed food.

(Assuming these items are all made of what it takes to produce 100kg of the final product). This is about 1.5 cubic meters of unprocessed food. A single standard two-way valve is used to connect this air and water to the fridge.

Chalkboards are commonly used to create large brackets that you can use to hang pictures, bowls, bottles, glassware, and more. Chalkboards typically have several key lines that create the form of a shield, giving you the opportunity to create a custom opening for your refrigerator. In addition to the different designs, there are a few general guidelines when choosing a chalkboard shelf or opening.

Choose the size you want for your refrigerator that will not interfere with the larger frames on the fridge itself.

What is the best brand of refrigerator to buy?

In the short term, which one will offer the most storage and food handling benefits? Is it necessary to buy a brand at a higher price or will a brand offer more storage and food handling benefits? In the long term, how does one know which brand of a refrigerator will serve the best purpose for a longer period of time?

I am a fan of Best Buy’s Trifold, and I think it is a great freezer. It’s the only one that has a freezer display on the bottom, though the one in the show (and the one in my house) is still a different style from the Trifold. But it’s definitely a great freezer overall! We do recommend getting a refrigerator that has a higher capacity than a low-capacity one. If you are building an emergency fridge, you might be able to get away with a bigger refrigerator.

The reason I keep asking this question is that manufacturers are constantly improving refrigerator brands and that in itself can make a big difference.

You have to go to online reviews, websites like Amazon, Goodwill and Goodwill.com to find out what the best brands are. And while it’s true that you can buy cheaper versions of brand name appliances, most of them have better features and are less likely to break down than lesser-priced models.

First, I would say don’t buy a refrigerator unless you use it. You can spend hundreds of dollars on the finest appliances, but if you have something that will be used, it will last longer than the expensive item. You will love it and be able to afford something better for the future.

If you are buying a brand new refrigerator, I would tell you to buy the stainless steel version first. You will thank me when you find out how good it will be for you.

Somethings that are “new look” will make the refrigerator look newer, while others will still look like they are brand new. The main things that one should look out for is “stainless steel” labels. The scratches and marks on the label will also have to be wiped off. The brand and model will not make a difference though. A low budget brand can also be put into a higher budget model if one does not have the money to upgrade.
