You know what a Robotic Pool Cleaner is?

Robotic pool cleaners are become popular in our life to help us clean our pool easily and effectively. They are low-voltage, self-directed automatic pool vacuums that clean the floor, steps and walls of a residential, public swimming pool. There are some famous brands in market such as: Dolphin, Aquabot, Maytronics,…

To make the pool cleaner work, we will connect a transformer to a standard wall outlet and a 30 to 100 foot-long power cord then connects the transformer to the best  pool cleaner.

Best pool cleaners are safe to operate.

They are totally safe so don’t worry you will be dangerous when using. Even though the transformer runs up to 110 or 220 colts AC, it drops the voltage down to a much safer 24 volts DC to power the unit. That is how they safe when operate.

How Robotic pool cleaner work?

Robotic pool cleaners work based on using two electric motors: a drive motor which moves the unit around the pool. Some cases, we will use a jest drive in place of wheels which are driven by an electric motor. And a water pump which using to sucks dirt into the device’s filter.

Nowadays, there are many robotic pool cleaners are automatically and computer-controlled using the most efficient path to clean your pool’s special surfaces. You will surprise about their performance. You will see how efficiently they work. It will help you save money spend on chemicals and energy compared to less smart units which rely on your pump’s circulation system.

Moreover, some robotic pool provide a remote control which you can use to drive the system from a far distance such as where you seat, very useful and convenient.

Save energy and cost for maintenance.

Compared the normal pool cleaners, robotic pool cleaners are not connected to the pool’s water pump, different from a pressure or suction-based cleaner  so there are not additional back pressure on the pool’s system. It will help you avoid using a booster pump or install new plumbing, which saves a lot of cost.

Robotic pool cleaners help Save energy and cost for maintenance.

1. Contact Adhesive Drive

The rubber tracks on Robotic Pool cleaners which have a big sticky contact patch on them, these will adhere to vertical pool surfaces better than plastic tracks and wheels. This design minimizes slippage on horizontal surface so it will save time on cleaning with this robotic pool cleaners.

2. Intelligent Navigation

Surely when your pool cleaners using intelligent navigation software to control the route, you will save time to clean and reduce energy consumption also.

3. Variable Timer

You will control the working time for the pool cleaners by setting up a variable timer. Your pool cleaner will only turn on when needed. This feature will help triple your energy efficiency.

Great filtration

We can see a robotic pool cleaner work as an excellent pool filter which is easy to clean. pool filter that’s easy to clean.  With a mesh down to 2 microns which is not common for a filters, these robotic pool cleaner can clean even the finest particles.

Beside there are other advantages we can consider buying a best robotic pool cleaner. List 10 great features make us want to buy a robotic pool cleaner can be listed as below:

What Types Of Guns Do You Need In Your Arsenal?

When building your survival arsenal, even when it’s an arsenal on a tight budget, there are two words that I want you to keep in mind: ‘quality’ and ‘versatility.’

Gun Rifle

Why am I ask you to remember these two words? The reason is because very gun you have in your survival arsenal needs to be a well-made and quality firearm that won’t let you down, and it also needs to be versatile in that your select firearms that fulfill multiple purposes. This way, your arsenal can be the very best it can be.

What I want to do in this chapter is to go over some specific types of guns that you should consider including in your arsenal. Does your arsenal absolutely need to have each and every one of these guns? No, but it is preferable that you have as many of them as you can.

Here are the basic types of guns that you strongly need to consider including in your arsenal:

.22 Semi-Automatic Rifle

No gun collection is complete without a .22 semi-automatic rifle, even the smallest of gun collections. The .22 rifle is simply one of the most ubiquitous and versatile types of rifles there are. The reason for this is because there is simply very little that it can’t do. It’s not the best personal defense round by any means, and it’s not a suitable round for hunting large game either. Think to integrate your rifle with best bipod for AR 15 to get a more stable system during the shot.

That being said, there are still many reasons to own a .22 rifle. Let’s go over a few of them here:

  • You Can Stockpile Lots Of .22

The very fact that .22 LR is so light and small mean you can stockpile tons of it (literally). For example, in the same box that you could store 50 rounds of pistol ammo or 20 rounds of center fire rifle ammo, you could store literally hundreds of rounds of .22 LR without any real increase in weight.

  • Low Noise and Recoil

The .22 has substantially less noise and recoil in comparison to other calibers. This makes it an excellent round to introduce new shooters to or even just for target shooting on your own for fun.

  • Small Game Hunting

The .22 is a superb round for hunting virtually any kind of small game you can think of, from squirrels to rabbits to birds to raccoons and more.

  • General Homestead Use

The .22 rifle is also just a great rifle to have around the homestead. You can use it for vermin control or for taking a break from anything you’re working on to do some plinking.

Shotgun

Many people believe that a shotgun in 12 or 20 Gauge is the single most important firearm that you can own. Do I agree with that? Not necessarily, since you can’t conceal a shotgun on your person like you can a handgun. That being said, I do acknowledge that the shotgun is a highly versatile weapon and that no gun collection is complete without one.

Let’s go over three reasons why:

  • Home Defense

When loaded with buckshot rounds, the shotgun is a devastating close range weapon for home defense. There will be few weapons in your arsenal with as much stopping power as a 12-gauge shotgun loaded with buckshot rounds up close. Pick up some best edc knife for defense is a good idea for anyone want to have a quick solution.

  • Bird/Waterfowl Hunting

Swap out your buckshot loads for birdshot, and your shotgun has been transformed into an excellent waterfowl or bird hunting weapon.

  • Big Game Hunting

Now swap out your birdshot loads for single round slugs, and just like that you have a weapon that could be used for big game hunting such as deer. Granted, you have to get at closer range than you would a center fire rifle, but it will still work very well.

Pistol

Previously I mentioned that I think a handgun is the most important weapon to own because you can conceal it. There will be certain situations where you don’t want people to know what you have a gun on you, and a handgun is simply easier to conceal than a shotgun or a rifle.

Besides, another benefit to owning a pistol is that you can always have it with you strapped to

your side. In a disaster scenario, are you really going to walk around with a rifle or a shotgun slung across your back all the time? Probably not. You may have it leaning against a wall where you can access it quickly, but you’re not going to have it actually on your person.

In contrast to this, you can have a pistol on your person at all times. When danger happens when you least expect, all you have to do is draw your pistol and you’re ready to defend yourself.

You don’t have to waste precious seconds trying to access your shotgun or rifle. This holds true regardless of whether you own a semi-automatic pistol or a revolver.

Now as far as specific handguns are concerned, I feel that a 9111111 semi-automatic is the most important to own. Semi-automatics simply offer you more round count and faster reloading times than revolvers do. The reason I recommend 9mm as well is because it’s cheaper and more plentiful than other pistol rounds such as .40 S&W or .45 ACP, and since this whole book is about how you can build an arsenal on a budget, 9111111 should be the round that you choose.

Therefore, a 9111111 semi-automatic pistol should be the handgun that you have in your arsenal.

Defensive Rifle

A center fire rifle used for the purposes of defense is another very important firearm to own in your collection. The best choice here will be a semi- automatic, such as the AR-15, Ruger Mini-14,01′ th

AK-47.

While some people don’t think of a military style semi-automatic rifle when they think of defense in general, there are several reasons why a semi-automatic rifle is an excellent defensive weapon:

  • More Bullets Against Multiple

Attackers Semi-automatic rifles can hold twenty to thirty rounds in the magazine on average, which simply means that you’re going to have to do less reloading to do. This makes it a good choice for defending Semi-automatic rifles can hold twenty to thirty rounds in the magazine 011 average, which simply means that you’re going to have to do less reloading to do. This makes it a good choice for defending your lióme, property, or family against multiple attackers.

  • Better Stopping Power Than A Pistol

Pistols calibers are simply underpowered in comparison to rifle rounds. The 5.56x45mm or 7.62x39mm round coming out of your rifle barrel is going to offer greater velocity and penetration than your 9111111 or .45 ACP round coming out of your pistol.

  • Less Recoil Than A Shotgun

While shotguns have excellent stopping power, they also deliver much greater recoil than a defensive rifle will. This means you can fire off more follow up shots with your rifle than your pistol.

  • More Range Than A Pistol Or A Shotgun

Finally, a rifle offers you greater range than a pistol or a shotgun, which will be a major advantage to you if you’re trying to defend your property.

All in all, I think a semi-automatic is the best platform to choose for a defensive platform. That being said, you can use bolt actions or lever actions for defensive use if you have to as well.

The lever action in particular could be applied veiy effectively to defensive use as you can fire and reload it faster than the bolt-action. Next I want to talk about the importance of having a hunting rifle in your collection as well, and I’ll discuss more closely about how the lever action could potentially fulfill both the defensive and hunting roles.

Hunting Rifle

Finally, I also recommend that you own a hunting rifle that is capable of bringing down big game and tapping targets at longer distances than your defensive rifle can.

You have three main options here for a hunting rifle: lever action, bolt action, or semi-automatic. Semi-automatics such as the AR-10, FAL, or MiA tend to be very expensive, which means they aren’t suitable choices for those looking to build an arsenal on a budget.

Therefore, I would suggest that you take a look at either lever action or bolt action rifles for hunting use. If you opt for the bolt action, the two calibers I most highly recommend are .308 Winchester and .30-06 Springfield. Both are very plentiful and will drop nearly any kind of big game in the United States, and recoil is more moderate in comparison to heavier rounds such as .300 Win Mag or .338 Win Mag.

For a lever action, I would suggest the .30-30 Winchester. It is lighter than .308 and .30-06, but it’s still more than capable of bringing down deer or wild boars.

As I mentioned earlier, a .30-30 lever action rifle could be used for both defensive and hunting use. No, it doesn’t have quite the power of a bolt action rifle firing .308 or .30-06 does, nor does it offer the same capacity or rate of fire as an AR-15 or

AK-47.

Nonetheless, lever actions still hold a few more rounds than bolt actions do, and you can generally fire and reload them faster as well. They also tend to be less expensive than semi-automatics like the AR or AK. If you’re on a serious budget and are looking for a rifle that could be used for both purposes, I would not be opposed to looking at a lever action model.

Types of the band saw blade and general rules for usage

The band saw blade is one of the main parts of the band saw and it has the most important influence on machining workpieces. Depending on your job’s requirements, you can choose different types of blades. There are four main types with particular tooth patterns: regular tooth, hook tooth, skip-tooth and wavy-set. Now, I will explain clearly about these kinds of saw blades.

maxresdefault

Regular tooth

The regular tooth consists of straight faced tooth with deep gullets. It is used for general metal cutting.

Hook tooth

The hook tooth saw blade is created with widely spaced teeth and deep gullets, it is used to cut some soft materials such as plastics, non-ferrous metals, and hardwoods.

Skip tooth

The skip-tooth, with wide set teeth, often breaks up the chips. It is suitable for cutting soft non-ferrous metals namely aluminum, copper, zinc.

Wavy-set

When using to cut some kinds of metals such as ferrous metals, you should choose a wavy-set blade.  The wavy-set has tooth which are set in groups with increasing to left and right. It is generally used for cutting difficult cutting shapes such as sheets, tubes, pipes and small shapes.

GENERAL RULES FOR USAGE

Even for the best band saw, there are some rules you need to follow to have the best effectiveness and works safely.

  1. Before cutting, you need to check that the band saw blade is properly sharpened and the blade damaged or not when it is overheating. The saw blade is purple color after cooling.
  2. The band saw blade must be properly straightened. Remember that do not straighten the blade too much because this can cause disruption of the blade.
  3. The guidance of blade and guiding wheels must be clean from chips. The distance between the top guidance and the workpieces should be as possible so that the blade achieves maximum stability when cutting.
  4. When cutting the workpieces, you should hold the cutting material with both hands. Do not use extra force on the blade.
  5. After starting, ensure that the proper cutting speed is achieved. Do not shorten or slow down the cutting cycle by friction of the blade.
  6. While cutting big dimensions, it is important to use a fixed clamp. Put materials in the band saw carefully.
  7. It is necessary to replace the band saw blade and regular maintenance (even if not dull). A new saw blade need to fit for your machine.
  8. Do not let the band saw to heat up exceeding the permitted level. If this happens, stop cutting the blade immediately and after cooling the saw blade and sharpen it again. You can also check the straightness to prevent heating from the blade.
  9. Replace or adjust the band saw blade if it is broken or cracked.
  10. After finishing cutting process, do not keep the band saw blade straightened, need to loosen it.
  11. During cutting process, the saw blade must be cooled immediately after machining materials.
  12. Use suitable coolants for the machine with the appropriate rate.

Here is basic information about the blades and some best tips for usage. Besides, you can also check more extra details in the band saw reviews. I hope that they are useful for you in using the band saw.

How to use a table band saw

The table band saw can make quick cuts and is precisely in creating projects with wood in a home workshop. However, using a table band saw requires extreme care, but if you do it in the right way, the results are worth the effort.

dougherty-3point-tree-saw-8

Steps 1

Decides the type and size of machine you need. The table band saws are usually slightly smaller than their peers. Here are some points you should consider:

Capacity: Capacity. There are two measures to the ability of band saws, one describes the width of the cutting that the band saw is able to do and the other is the thickness of the material to be cut. A common belt saw can cut from 22.5 to 25 cm (9-10 inches) wide and can cut through materials from 7.5 to 10 cm (3-4 inches) thick.

The cutting speed:  A Band saw with adjustable speed is a little more flexible than the single-speed machine, but it costs more. For reasons of practicality, a saw with one speed work for most projects involving cutting wood.

Blade length: Although the length of the blade does not affect the cutting itself, it is better for you to select a saw that uses a common blade size available in different types of toothed blades and blade widths.

Features of the table: That is, the table band saw which has table made from heavy and durable materials such as cast aluminum is able to provide more versatility than the fixed and simple tables.

Easy to use: Make sure no special tools or complicated setup procedures are required.

Security: Choose a machine that has a double insulation or grounding plug and provide good visibility around the cutting area. It should have a lock switch to prevent children turning on the saw if they have access to it without supervision.

Power consumption requirements: Most tools of this type operate on standard household electrical voltage depending on the country in which you buy. The largest and most commercial or industrial machines may require a three-phase system that is not available in a common household.

Step 2

Set your saw. Read all manufacturers’ instructions and safety information before assembling new tape. Sets the machine at a comfortable working height, usually just above the waist of whom operates. Make sure you have enough available light sources. The table band saws must be secured to the table to prevent the machine from toppling over and new machines should come with fasteners for this purpose.

Step 3

Select the correct blade for your cutting project. There are two criteria for this choice, the width of the blade and teeth per inch (DPP). Here are some examples of both:

Blade width: It refers to the physical width of the blade itself. The narrower blades allow shorter turning radius for intricate spirals work. The broader blades tend to be more durable, allowing less flexibility and dissipate heat more efficiently.

  • The blades of 4 mm (1/8 inch) blades are narrower to cut the smallest possible arc.
  • The blades of 7 mm (1/4 inch) are narrow blades to cut a small circle or arc.
  • Blades of 9 mm (5/16 inch) are blades for all purposes. They can make a cutting radius of about 7.5 cm (3 inches), depending on the hardness and thickness of the wood, and are a little more durable than the thin blades of 7 mm (1/4 inch).
  • The blades of 10 mm (3/8 inch) are unsuitable for sharp curves. They give very good results in straight cuts and miter and usually retain their edge longer than thinner blades.

The number of teeth per inch determines the effect of the cut in the material you want to cut. A high DPP will create a smoother cut, but cut at a slower rate, while a low DPP cut faster, but make a rough cut.

  • DPP 16 blades have very small teeth and usually very little inclination or angle deviation in each tooth. Normally they used to cut very thin material, less than 14 mm (1/2 inch), at slower speeds.
  • DPP 12 blades are used for thin and smooth cuts of wood up to 2.5 cm (1 inch) thick, for which a smooth finishing cut is required.
  • 8 DPP blades are almost at the same size as the blades of hand saws for all purposes and make a smooth cut of wood up to 5 cm (2 inches) thick or more at a faster rate.
  • Blades interspersed with teeth, adjustable hook teeth and teeth are also available for specialized purposes cuts.

Another specification of the blade that you have to consider is the thickness of it. The smaller wheels of the band saw (pulleys type rollers that hold and guide the blade) must be thinner blade, as this is continually bent while turning around these components.

Step 4

Make sure the saw is disconnected when performing the following steps. Merely turn the saw is not a safe alternative, because it is possible that the pressure switch while you work on the machine.

Step 5

Adjust the blade tension of the band saw according to manufacturer’s instructions. Most saws have a screw or knob to adjust the tension on the top and back of the machine. The blade should be tight enough so it does not slip or diverted to cut, but a too tight blade can damage the saw. A common way to test the blade tension is to lift the blade to the maximum height and press the sides of it. It must move about 3 mm (1/8 inch) to apply a few kilos (pounds) of pressure in this way. However, see the manufacturer’s instructions for specific information according to your machine.

Step 6

Check the alignment of the blade. For this step you need to open the cover on the upper wheel assembly, which is normally closed with clamps or screws with knobs. Turn the upper wheel with hands and watching the position of the blade on the wheel. You must turn the wheel center without moving or diverted for 10 or 20 complete revolutions. Turn the adjustment knob to the correct alignment position of the blade on the wheel if it does not rotate as it should. Close all access panels to complete this step.

Step 7

Set the blade guides. Most table saws have a movable guide blade extends under the cover of the upper wheel. Usually there is an adjustment knob or lever to lock or unlock the unit to allow quick and easy changes. The blade guide should be fairly close to the surface of the wood that you are going to cut, but not so close to lock or jam wood. Leave a space of at least 7 mm (1/4 inch) of the widest part of the timber and ensures the guidance in this position.

Step 8

Adjust the table saw. For a square cut, one that is perpendicular to the work table, use a square block or a piece of square wood to visually check the alignment of the sheet. If the saw is pre-set to zero in the angle indicator scale, using the zero mark or 90 degrees to facilitate this step.

Step 9

Set guides miter to make a straight cut. If your saw is equipped with these guides, they will hold the piece of wood in alignment between 90 and 45 degrees.

Step 10

Make the cut on the piece of wood that you use. Marking clear and easy to distinguish lines by using either soft lead pencil or pen which is suitable for this purpose. Do not use a pen ink timber, you should have a natural finish or dyed with a transparent or translucent ink!

Step 11

Check that you have the necessary space for cutting. You do not want to be cut in half just to realize that the piece of wood does not rotate or cannot pass through completely. Now it’s time to plug the saw.

Step 12

Make the cut. Turn the saw, let gripping speed and check that the blade is rotating in a straight and direct line. If you notice any movement or deflection of the blade, stop and check the assembly to adjust properly. Keep your fingers as far as possible from the saw blade and tape passes the piece of wood so that the blade cutting follows the mark you made.

Advice

  • You should give the machine a good maintenance and cleaning. Remove dust that accumulates in the dust ejection tubes and oil blade guide regularly.
  • Select an appropriate band saw for the entire range of your cutting needs. The table saws are suitable for limited spaces, but the biggest and the ground coupled machines are much more versatile.

Warnings

  • Always disconnect the saw to adjust or replace the blades.
  • Make sure you have sufficient lighting for the task you perform.
  • Use safety goggles and a dust mask when cutting.
  • A band saw and all power tools can be dangerous if not properly used. Use it in a large area enough to hold the piece of wood and blade passes by keeping your fingers at a safe distance.

Things You’ll Need

  • Suitable band saw blades
  • Bench or table saw to mount

band saw bigger

Making a helicopter from wood.

You need to prepare:

  • A small-sized Band Saw is suitable.
  • A Large piece of ¼ inch-depth Birch timber
  • Medium sheet of ¼ inch-depth Cedar timber
  • Metal rods for axles, Wood Glue, Drill and drill bits are necessary.

Now, let’s do it:

Be sure that you have already had your plans for your helicopter. It is easy for you to look for and download any plans on the internet.

Step 1: make the body of Helicopter

  • Place your plans on top of the birch timber and use a builder’s pencil to trace over them so as it indents the timber.
  • Using your band saw cut out the shape defined by the tracing paper which should end up being 6 ¾” long and 4” tall.
  • Cut two holes near the bottom 1 inch apart and 9/16” from the edges.
  • Cut three of these shapes in Birch and two in Cedar, then you have five similar parts.
  • Place them in turn: a birch, then cedar, then birch, then cedar, then birch. Now, you have the shape of the helicopter.
  • Finally, glue them together, ensure there is no glue run over the sides, use clamps to press the timber together at the four corner areas. Remember not to apply too much pressure

Step two: make rotor

  • Cut two identical pieces in birch timber to make the blades which should be 4 ¼” long and 1/2” wide. In each blade, cut a hole in the dead center.

Step three: complete the helicopter.

  • Leave the helicopter at least 8 hours to be sure the glue is set firm then drill a hole in the rotor blades center. You need to use sandpaper around the body to remove marks left.
  • Drill holes: a front and rear hole for the axle that are far from the front and back ½ inch and the bottom an inch
  • Combine the axle blade with the wheel and blade at the top of the helicopter by using the wood glue.
  • Leave the helicopter to dry. Using sandpaper if necessary.
  • To decorate the helicopter, apply over it clear oil before painting

Now, you have a wooden completed helicopter. Learn to practice more with tools and wood to create more interesting toys. It is an easy project for home wood enthusiast with only band saw and some extra tools.
