Now that you have a band saw in your hand, here comes the next question: how to use it correctly in safety, accuracy and efficiency? In this article, we will provide you with a basic, simple guide on how to use band saws.

1. Make sure you have enough power to supply your band saw with

This is actually something to be considered when you are choosing your band saw. You should make sure the power source in your workshop is what your band saw can go with, or vice versa. Fortunately, usually band saws are made to operate properly on the normal household electricity. If you are to go with big, industrial band saws, be ready to equip your workshop with 3 phase power for them to operate.

2. Set up your band saw

Each band saw has the instructions and manuals attached, read them carefully before setting up your saw, and pay special attention to the safety information. When you assemble your band saw, make sure it will have a comfortable height for your ease in working. Check the place you put your band saw, the light should be clear and bright enough.

3. Go with the right blade

Depends on its type and size of the wood you use, you will need a suitable blade. Check the width and teeth per inch (TPI) of the blade to choose the correct one. 

Blade width: The narrower the blades are, the shorter the turning radius; whereas a wider blade will last longer but will not be able to produce sharp curves. A blade’s width often ranges from 1/8 inch to 3/8 inch.

Blade TPI: The TPI of a blade will decide how effective the cut is. Higher TPIs help you to make smoother cut yet the speed would be slower. Lower TPIs, on the contrary, the cut will be rougher but the speed is fast. Normal blades have their TPI ranging from 16 TPI to 8 TPI.

4. Safety first

Do not leave the band saw plugged in when you need to adjust it. Even if you have turned it off, you should also plug it out. The switch can be accidently switched on at any time during your working time.

5. Pay attention to the blade tension

Adjust the blade tension of your band saw to a suitable one. If you leave it too tight, the blade tends to be damage easily while if the blade is not tightened enough, it can slip and shake when you are cutting.

6. Check the blade’s position

Open the cover of your band saw and check the blade’s position. The blade should run at the wheel’s center. If it is not in this place, you should adjust the knob to move it there. When you finish adjusting it, close the cover.

7. Check your blade guides

Normally, a band saw will have some blade guides near the place of the upper wheel. This blade guide can be move so choose a suitable position for it. Do not let it come too close to the cutting surface, they can jam the wood.

8. Mark your cut

On the wood that you are going to cut, you can use a pencil or a specialized marker for wood so that you can trace the line easily when cutting. Do not use an ordinary marker that will leave forever stain on your wood.

9. Check all the materials needed before starting your cut.

Stop halfway to find a missing piece of wood would be a frustrating experience so check all of your necessary materials before you start cutting. Then plug in your band saw.

10. Power on your band saw and begin to cut following the lines you have marked. During the cut, do not let your finger come near the blade. You should better buy a pair of safety cutting gloves. If you are cutting and your blade wobbles, stop. Unplug the saw and adjust it before resuming the cut.

Now that you think of buying yourself a band saw, there may be several questions that you have to contemplate. To get a basic hold of the information of band saws, you may want to read the band saw reviews. Basing on these pieces of information, you may have an idea of how to choose a good band saw. Yet if you would like some more general information, like a summary of what to look at when choosing a band saw, this article is for you.

Below are some brief guides on the basic features that you need to consider in order for you to choose the band saw that would be the best match of your needs:

1. What is your preferred size?

At first, look around your workshop and decide which size of the band saw that will be the best to assist you in your work with wood. The band saw should, at the same time, not too big to be placed in a suitable in your workshop and not too small to cut your wood piece. Normally, the size of a band saw is determined by its wheels’ diameter. Minus 1 inch, you will have the throat width which decides the largest piece that can be placed between the column and the blade. The maximum thickness that can be cut of the wood is determined by a spec called the resaw capacity. Therefore you should look at all of these measurements to choose the most well-sized band saw. For example, to have enough versatility, a band saw should at least has the resaw capacity of 12 inches.

2. How many wheels would you want?

If you look closely at the numerous options of band saws in the market, you will see that there are two basic types – regarding the number of wheels – offered: 3-wheel band saws and 2-wheel band saws.

The 3-wheel band saws, with smaller wheels compared the 2-wheel ones, usually requires the blade to change directions 3 times while functioning while the 2-wheel band saws have bigger wheels and require 2 times of direction change for blade. Therefore your blade’s life-span will be longer if you are to go with a 2-wheel band saw. However, 2-wheel band saws have much smaller throat than the other type. So, if you really need a big throat width, you can choose a 3-wheel band saw. But if the throat width is not your priority and blade lifespan is, then a 2-wheel band saw is the best option for you.

3. Choose motor that is powerful enough for your needs

A good motor with enough strength will help you to cut sharply, even with hard wood. If you are tempted by a band saw with inexpensive price, look at its motor’s horsepower before picking it up. Cheap band saws usually have small horsepower and will struggle when it has to cut hard wood. Unless you will only work with extremely soft wood, do not consider band saws with motors of equal to or under 1 horsepower; or else, your cutting speed and the shape of your cut pieces will suffer.

4. Pick the suitable blade with adequate teeth 

The teeth of a blade are normally counted by 2 methods: TPI, which means counting the teeth per inch, and PPI, which means counting the points per inch. For a normal wood-turner without any special requirements, a band saws having 3 TPI is good enough.

To summarize, this is your small check list to make if you are to buy a band saw:

– Define the size of the band saw

– Choose the number of wheels

– Go with a motor that is strong enough

– Check the density of teeth on the blade

Will it be surprising for you if you know that memory foam were originally invented to serve in the space industry? You can find below some facts about the story of memory foam.

1. New material of NASA

Back then in 1966, NASA wanted a new material to enhance the safety of their aircraft cushions. Basing on this request, memory foam, which is sensitive to temperature, was created.  It can easily match the shape of the thing pressing against it but slowly get back to its original shape after the contact is gone.

NASA then decided to commercialize the material. By 1980s, the public had the chance to experience memory foam for the first time. Yet during this decade, the manufacture of this foam is still difficult and the quality is not always ensured.
In 1991, memory foam was finally used in making mattress. Gradually, it has been used to make mattress pads and mattress toppers as well. From that time on, memory foam has been widely popular in this industry.

2. Memory foam mattresses’ advantages

Usually, mattresses made from memory foam have greater density than ones made from other foam. As a consequence, memory foam mattresses are firmer, heavier as well as more supportive for users. They often cost more than normal mattresses. Memory foam now has open-cell structure which can react to body temperature and pressure. When a sleeper lies onto the mattress, it quickly molds to his body’s shape and thus lessens the ordinary pressure points, reduce the sores etc…
Moreover, when the body heat increases, memory foam can react and become softer, therefore the sleeper will feel more comfortable.
Memory foam is also known for its ability to resist dust mites. Normal foam mattresses can be a good place for mites to live after several years in use, yet memory foam – composed of polyurethane – are not at all mite-friendly.

3. Some cautions against memory foam mattresses

As much as memory foam mattresses provide us with comforts, there are however some cautions that we should take on using it.
Firstly, memory foam can retain the heat of our body. Therefore, sleeping on a memory foam mattress in a hot summer night may be less comfortable than normal. Many memory foam mattresses are now produced with cooling feature to reduce this.
Besides, as memory foam is synthesized material, brand new memory foam mattresses may have some chemical odors, which are irritating to some people. Yet this problem can be solve by exposing the mattress to the air or the wind at least 24 hours before putting it into use.
It is also strongly recommended that you do not use memory foam mattresses for your babies. Memory foam mattresses can be difficult for infants to turn over; therefore there are risks of suffocation. If a baby rolls over and presses his face against the mattress, memory foam may block air passage and cause it difficult for the baby to breathe.
