Band Saw Guides – Which One Do You Need?

There are kinds of band saw for you to select. So, you should know what they are and how to use them.

 

In order to get your vertical band saw working effectively for you, you should familiarize yourself with the various different band saw guides that are available.

 

You should also spend a little time understanding how to maintain them and keep them in tiptop shape. This will have a big impact on your blade performance and as such on your productivity.

 

Since a bandsaw guide can cost about $100 or so, you will be well rewarded if you look after yours, as you will not have to replace it as often as an uncared for guide in bad condition. There are many types of guides on the market today but it the main they are just variations of the ones I have listed below.

 

Sandwich Bandsaw Guide

 

These guides also go under the name of block guides and they hold the blade in place during the cutting. They are often used in sawmills and in situations where the need to produce volumes supersedes the requirement to save the blade.

 

Retrofit Roller Band Saw Guide.

 

This is basically a cross between two other types of guide, the Roller and the Bottom Control band saw guide. Under normal conditions the lower part of this guide has no contact with spinning blade. However if you hit a knot in the wood or some other type of bad spot, it will really come in to its own. It then prevents the saw from lurching into the timber and spoiling the cut, but after that it just sits there until the next time it is needed.

 

Grease Roller Guide.

 

This band saw guide has bearings that keep the blade straight as it passes between them. To prevent friction these bearings need to be free moving, hence the need for grease. So you must make sure that your guide can be greased. It is just like your automobile requires oil, otherwise over time the engine will seize and you will grind to a very expensive halt.

 

So as I said at the top, a little time spent maintaining your band saw will pay dividends down the line. It is always a good idea to refer to the manufacturers handbook for best advice on what steps to take and when.

 

And that by the way can go for any machinery you own.

Guide to the Different Types of Band Saws

Band saws come in many different shapes and sizes, each with their own unique selling points and purpose. The band saw is regarded as one of the most versatile power tools on the market according to Popular Woodworking Magazine, renowned for its ability to cut through just about any material, however, it is not often the first machine purchased for a workshop.

 

The material you’re working with and type of project you’re completing will determine which of the different types of band saws to use. Vertical, horizontal, timber, and metal, cover just some of the band saws available.

 

This article will take you through some of the different types of band saws and some of their common uses, as well as a general guide to band saw safety that can apply to any type of this powerful tool.

 

Metal Band Saw

Of all the different types of band saw, a metal band saw is the ideal power tool for jobs that require you to cut through tough metal.

 

Metal cutting band saws generally fall into two categories, the vertical band saw and the horizontal band saw. The horizontal metal band saw is generally used to cut stock down to size, whereas the vertical one can be used for more intricate jobs such as filing, polishing, and contour cutting.

 

They do require some extra maintenance though and generally have some additional features built in. A coolant that keeps the blades lubricated and cool, as well as brushes or brushwheels that prevent metal chips from being caught in the blade, are both common to find on these types of band saws.

 

Unlike other saws, band saws have the unique ability to cut through a range of materials other than just wood, making them a popular tool in most workshops.

 

Wood Band Saw

A wood band saw is a popular choice among amateur and professional woodworkers. Often compared with the table saw as one of the most important power tools in carpentry, the wood band saw is a truly versatile machine.

 

While smaller stationary band saws are used in workshops, timber mills also operate large scale band saws for ripping lumber. The band saw has the unique ability to work with timber that’s of a larger diameter, and because they have a smaller kerf, or cut size, there is less of the quality timber wasted.

 

Wood band saws operate the same as any band saw, with the blades located on a continuous loop of metal teeth which perform succinct cuts through the timber.

 

Horizontal Band Saw

The horizontal band saw is one of the broader categories of band saw, favored by both amateur and professional carpenters. These types of band saws are useful for cutting longer materials down to size, however, not so ideal for producing complicated shapes or curved lines.

 

A horizontal band saw works by holding the material stationary while the band saw blade swings down through the cut. Once the cut is complete, the saw will automatically turn off with a switch trip to avoid potential injuries to the operator.

 

Some of the benefits of using a horizontal band saw include:

 

  • A quieter cut than most saws, making for a calmer workspace;
  • Extreme precision and accuracy when cutting straight lines;
  • The ability to set up your cut and then leave the machine to complete it, even turning off automatically once done;
  • Ability to cut wood, metal and plastics with ease;
  • No heat-affected zone after use, meaning safer operation with less risk of injury

 

Vertical Band Saw

A vertical band saw varies from its horizontal counterpart in how it cuts through the material. The saw itself doesn’t move, but rather the workpiece moves through the blade to create intricate cuts.

 

A vertical band saw is so versatile it can be used to create complicated shapes and lines that other types of band saws can’t compete with. As well as being adept at cutting complicated shapes, the vertical band saw can also perform precision cut straight lines, making it a great all-rounder power tool.

 

These saws have a superb cutting capacity and the ability to cut through materials fast, and with brush wheels installed they have safety measures in place to ensure chips don’t become stuck in its metal teeth.

 

Not only is the vertical band saw capable of cutting with ease, it also usually features a built in welder. The welder is useful for creating new blades or repairing old ones, and can even route the blade through the center of a part so that it can make interior cuts to the material.

 

Safety Guide

Although they’re often touted as one of the safest power tools around, you still need to be aware of the safety precautions for operating a band saw. A stationary band saw poses less of a threat than machines with a movable blade or saw which lowers their risk for injuries.

 

According to the Fine Woodworking Magazine, there are 12 cardinal rules for band saw safety that should be followed. These rules apply to all types of band saws and apply to working with any type of material, however, some styles may have extra rules regarding their safe operation.

 

  1. First and foremost, you should always consult the individual guidelines for your band saw as recommended by the manufacturer.
  2. Always ensure that fingers and other body parts are kept out of the path of the blade.
  3. When approaching the end of the cut, be sure to decrease the feed pressure.
  4. While the saw is in use always keep the wheel covers closed.
  5. Adjust the upper guide roughly quarter of an inch above your material before use.
  6. Always utilize the blade guard and keep it in place.
  7. Before changing blades, disconnect the band saw completely from its power source to avoid any accidental starts.
  8. As with any power tools, always wear eye protection while in the workshop.
  9. In the case of a broken or errant blade, ensure the machine has come to a complete stop before opening the wheel covers.
  10. If you have chips stuck in the throat, make sure you stop the saw before clearing the obstruction.
  11. To keep your fingers away from the blade, use push sticks that are stored in your miter slot.
  12. Always keep your workpiece in contact with the table at the exit point of the blade.

 

Conclusion

Not only is the band saw adept at making curvaceous cuts, but they can also perform precision cross cuts and rip lumber. If you have a quality band saw in your workshop you’ll already know how smooth their cuts can be, and performed with minimal effort.

 

If you’re looking for a band saw for your workshop, you’ll need to determine how much space you have available. There are some amazingly powerful and smaller bench top models that can still get the job done without taking up too much room.

Learning to use a band saw correctly will allow stronger, sharper cuts while increasing your efficiency with the tool. A band saw can be very versatile tool in the right hands.  Learn the band saws strengths and weaknesses to get the most of the tool.

 

Band Saw Blades

 

Properly maintaining and storing the blades of a band saw allows getting the most out of the saw. The versatility of the band saw comes from the various type of blades.  Identifying the correct blade for each job is a significantly important task.

 

Mitre Band Saw

 

Understanding exactly what a mitre band saw will do will help you decide if a mitre band saw is a must have tool for your shop or just a convenient extra item. Mitre band saws can definitely a powerful useful tool, but for many it is a rarely used tool.

 

Using a Mitre Band Saw

 

The Mitre Band Saw is a precision cutting tool and must be used correctly to get the optimal output for you project. Understand exactly what you are doing with the saw and you will increase your output while making the best possible cuts.

 

Band Saws – How Much Saw Do You Need?

 

When looking to cut precise curves in wood, in most cases there is no better tool to choose than the band saw. That being said, a quality band saw will do a lot more than just cut curves. They are great for cutting tenons and some smaller rabbets, for ripping small pieces of stock and for resawing thin strips from larger pieces of wood. There are two main types of band saws, floor-standing cabinet models, and units that are shorter, for mounting either on a dedicated stand or on a bench top. Cabinet models are typically built for professional use, whereas the smaller units are better suited for the home-based woodworker. The cabinet models have more features and larger motors, and usually feature a stronger frame which leads to more consistent cutting. That isn’t to say, however, that one cannot get professional results from a bench-mounted band saw.

Common Differences between Cold Saw and Band Saw Machine

A cold saw and a band saw machine can be compared on the basis of several factors which include the shape and angle of the cut, the type and the size of materials to be cut and whether the materials need to be hot or cool. Both are used for different purposes as it includes specific features.

 

A cold saw is a machine used to cut metal and it includes a round blade made of iron or steel that rotates to cut the metals. Band saw machines are mainly used to cut wood although some of these saws are designed to cut metals too and include a metal ribbon which is struck on two wheels. These wheels turn the ribbon at a programmed speed to cut wood or metals.

 

Portability: Another important difference between these is its portable feature. While cold saws are portable and can be hand held to cut metals, band saws are mounted onto tables. It is a stationary device and the bands can be either vertical or horizontal.

 

Varieties: These are available in two varieties which include non-ferrous and ferrous. The non-ferrous saws are capable of higher speed, better performance and distinctive finish. The ferrous saws are basically heavy duty saws which are used in factories where includes low cutting costs. The surface finish is less fine with the use of ferrous saws as compared to non-ferrous saws.

 

Cutting Material: Cold saw is mainly used to cut only metals whereas band saw machines are used to cut wood. Unlike any other saws, the ferrous and non-ferrous have developed technologically over the past several years. These are designed to protect the coating of the metals.

 

Desired Shapes: The band saws can be used to cut materials into desired shapes as it can be mounted on to the tables. This is quite difficult with other types of saws which are portable and hand-held. The stationary band saws can be used to cut irregular shapes quite easily as it includes both vertical and horizontal saws.

 

Shapes and Sizes: Band saw machines are available in a huge variety of size and shape. This offers different cutting patterns to consumers. In addition to wood, band saws can be used to cut metals and stone too. The blades of these saws are susceptible to damages if it is used improperly. Moreover, the life span of these blades is short compared to the other types of saws used for cutting metals and wood.

 

Cool Cutting Action: With the use of cold saws, the metal and the blade remains cool during the cutting process. This ensures that the metals, which are being cut, remain intact. It seldom loses its shine and shape.

What’s the Best Approach for Sawing Aluminum?

Band saws have emerged as a possible tool for this challenging cutting job

 

Interest in incorporating more aluminum parts into final product designs is causing fabricating operations to reconsider how they approach sawing aluminum. Traditionally, the conversation centered around circular saw technology when it came to cutting aluminum, but now new band saw developments have helped to expand the discussion.

 

With the continued focus on using lighter materials wherever possible, particularly in the transportation industry, metal fabricators are interested in learning about the best ways to process aluminum materials. Of course, this affects every shop floor activity, including sawing.

 

This interest in lighter-weight material appears to be a long-term trend. Because great opportunities await those fabricators able to process aluminum efficiently, they need to be aware of cutting technologies that can help them do the job. If the focus is on sawing, the question is, do band saws or circular cold saws cut aluminum better? Technological advancements have been made in aluminum sawing with both types of saws, and the answer is often a very firm “It depends.”

 

A Look at Circular Saws

One of the more traditional methods of sawing large-diameter aluminum has been with very large circular saw blades. This sawing method caught on because of the speed at which the aluminum could be cut compared to band sawing. The circular saw enters the material at a high speed and maintains that same speed throughout the entire cut, even upon exiting the material. Saw manufacturers call it a constant speed and feed rate.

 

Traditionally, band saws struggled with this because the blade could be damaged quite easily if it entered the metal at a high speed. The “gumminess” of a metal like aluminum would wreck a band saw blade if it entered the material fast. New technological advancements in band saws—which will be discussed later—have changed this somewhat.

 

Large circular saws require a large upfront capital investment. That should come as no surprise because the equipment’s size plays an important role in its ability to cut aluminum so quickly. For example, a circular saw cutting a 20-in.-diameter aluminum billet would require a blade of at least 40 in. diameter, and more realistically about 50 in. Of course, the equipment has to be large and sturdy enough to turn that large blade at a consistent and high RPM.

 

When it comes down to issues such as the finish of the final cut, the circular saw stands out as a suitable choice. By generating a very good finish, the fabricator may be in a position to eliminate a secondary finishing operation, which can result in dramatic labor savings. This is especially evident in fast cutting of single-piece, small-diameter material. For example, in aluminum extrusion cutting, production volumes can be as high as 5,000 parts per shift, and the end finish is expected to be very clean.

 

The fact is that circular saws cut aluminum so fast and effectively that a fabricator really needs to develop a productive means for moving material in and out of the saw. A material handling method is either an incline or flat-loading magazine on the input side, coupled with a high-speed output conveyor for sorting of the finished parts. This maximizes the aluminum cutting power of a circular saw.

 

However, it should be pointed out that while a circular saw delivers a much cleaner cut, the blade will remove a nice chunk of the aluminum because of the blade size. For instance, a 40-in.-diameter blade is about 0.33 in. wide.

 

A Look at Band Saws

Band saws were never really considered to be a wise choice for aluminum cutting, but that has changed recently. With the advancements in band saw technology, large aluminum billet now can be cut almost as quickly as with large circular saws.

 

The best news for a fabricator is that an aluminum cutting band saw requires a significantly smaller capital investment than a circular saw. Simply put, it’s a smaller piece of equipment because its blades are smaller in comparison to circular saw blades and do not require a very large operating footprint to be effective.

 

To achieve efficient aluminum cutting, band saw technology had to overcome the challenge of turning a blade at a much higher speed than is needed for traditional steel sawing—in fact, as much as 10 times the surface feet per minute (SFM) as steel requires. Band saws now feature ramp feed and speed, which means the blade enters the cut slowly, ramps up, and then exits the cut slowly. Entry and exit are two areas where the possibility of blade damage is greatest, but this controlled process eliminates that. In addition, blades have advanced so that they can revolve that fast around the wheels and be flexible enough not to break.

 

Further, these newer aluminum cutting band saws provide good control of the blade. The equipment’s ball-screw, servo-drive downfeed helps to ensure that the beam is pushed firmly through the material at a feed rate up to 22 inches per minute. To generate the high blade speed (up to 4,000 SFM) requires the appropriate combination of horsepower and torque within the gearbox and motor, so that even at high speeds the equipment is not overworked. Current band saw technology hits all of these very important benchmarks.

 

If a fabricator is cutting aluminum parts and other materials at lower volumes, say, 1,000 parts or fewer per shift, then a band saw can be a solid performer. If the aluminum material is greater than 7 in. diameter, today’s band saws are probably a good choice for the job. Also, if the squareness of the cut has a high tolerance, the band saw will be able to deliver.

 

Fabricators also should be aware that a band saw blade is thinner than a circular saw blade, typically about 0.042 in. thick. This results in a significantly smaller kerf removal when compared to the circular saw blade, generating material cost savings over time.

 

How far has band saw cutting of aluminum come? Band saws are now cutting 11-in.-diameter 6061 aluminum bar in 14 seconds. That is 94 sq. in. of material, which is equivalent to a removal rate of 400 sq. IPM. This means that band saws are now able to cut at 3,500 SFM, which compares favorably to previous generations of band saws that could cut only up to 500 SFM.

 

See the Saws

The best saw for aluminum sawing depends on the application. Circular saws generally are suitable for cutting aluminum between 0.5 and 6 in. diameter, for high-volume jobs (up to 5,000 parts per shift), and for the best possible finish on the cut piece. Band saws generally make sense for aluminum stock of 6 in. diameter and larger and for shops that are interested in high-speed cutting of aluminum but also frequently cut other materials.

 

Perhaps the most important point is that band saws are now capable of providing a cost-effective alternative for aluminum sawing, which wasn’t the case several years ago. With the growing reliance on aluminum as part of future product designs, fabricators now have one more tool in the toolbox to tackle this challenging sawing job.

Some Tips of Band Saws

There are two common styles of band saws, the three wheels and the two wheels.  Three wheel band saws give you a greater throat depth than a two wheel having the same blade length; two wheels are much easier to align properly and keep aligned during use than three. From here on I’m only going to talk about the two wheel band saws.

 

The frame construction is the first thing to look at. Smaller bench top band saws can be pressed metal, plastic resin, steel or cast iron. Larger band saw will be either cast iron or steel. The pressed metal and plastic resin are not as rigid as steel or cast and these saws are definitely meant for light duty hobby and craft work.

 

You are much better off to get one that has a steel or cast iron frame. They will last longer, run smoother and the blades will track better. Larger band saws all come with cast iron or steel frames so you do not have to worry about the rigidity. Each type of frame has its advantages and disadvantages. Steel frames are the most rigid and therefore more stable and smoother running, but they are also more expensive. Cast iron frames are cheaper and often allow you to increase the height capacity using a riser, but having cast parts they can crack and fracture through use. In most home shop applications this is not a large issue but it depends on the amount of use.

 

Motor size can range from 1/6HP to 1/3HP for bench top and from 1/2HP upward to 3HP or larger on big industrial machines. The smaller the motor the harder it has to work. If you mainly work on smaller crafts or model construction, the smaller bench tops are fine, but in the long run try and go with one, which has 1/4HP or larger. If you build furniture, cabinets or larger projects go with a floor model with at least a 3/4HP motor. The 1/2HP models just don’t have enough power for heavier cutting. If you want to cut metal, and then make sure the machine has slower speeds, down to less than 200 rpm instead of the approximate 3000 rpm for woodcutting.

 

There is not a great deal of difference between an open and closed stand. Open stands are just as stable and in some cases more so, but they do allow your motor to be out in the open where dust can get into it. If you have an open stand make sure you blow the dust out of the motor on a regular basis. Closed stands keep the motor cleaner, but not totally dust free, plus they offer storage space for wrenches, hex keys, manual and accessories.

 

EVERISING has been specializing in mid to large size band saws and circular saws since 1982.

Comments Off on Some Tips of Band Saws

Band Saw

A band saw is a very popular power tool. A band saw has a metal blade with teeth that will cut through different types of work pieces. These saws are great for woodworking, metalworking, and for cutting just about anything imaginable. Take a look at the various types of band saws and find one for you.

 

For people that do metal working, band saws are a necessary tool. These saws come in both a horizontal and vertical design. Your band saw will be able to cut through numerous types of metals. Nevertheless, in order to do this, you will have to make sure that you have the proper blade for that type of metal. Depending on what type of metal your cutting you may need a more heavy duty blade.

 

Band saws are great for timber cutting. Most of these saws will be found at a timber mill and they use very large band saws to make the first cut by ripping the lumber. In ripping lumber, the band saw will cut strips of the whole tree to make it manageable for shipping or processing even further. The large band saw also helps reduce waste and get the most out of every timber. Band saws used in timber mills are generally very large and can be very dangerous. Proper maintenance is important with these to keep them up and running at their best quality.

 

Most meat saws are a form of the band saw also. To be sterilized, the band saws have a stainless steel construction that makes for easy cleaning. Blades are also heat treated and generally have a very fine tip for making a quality cut of meat. These saws make breaking down an animal and shipping it to a store or getting it processed much easier and more efficient. This also reduces waste with a detailed cut.

 

There are also band saws for personal home usage. Some people need a band saw for construction on their home or certain projects. They also may have a hobby that requires a band saw. You don’t have to own a commercial business to own band saws; they are available at a variety of retailers for the public to purchase. There are many different types of band saws that you can buy and bring into your home.

 

With any band saws, there are different ways to feed what you want to cut into the machine. There is a gravity feed that allows the saw to use its own weight to feed the wood, metal, or meat through the machine. If you are purchasing one for personal use, it’s probably gravity fed.

 

Hydraulic fed band saws use a piston to move the saw through the piece of wood or whatever it may be cutting. This of course increases the cost of the band saw, and generally is only installed on the more heavy-duty saws. If you have a production band saw, most likely, it has a hydraulic feed.

 

Whatever your needs may be for band saws, there are a variety of styles out there that will match what you are doing. Check out a close retail store that specializes in tools and find the band saw for your job. Be sure to invest in one that was designed for what you were doing and be safe.

To Get the Most Out of Your Band Saw

Any band saw can resaw. The question is: “How well and how thick?” The first thing you need to decide if resawing on your band saw is an activity in which you are likely to engage frequently, occasionally or never. For those of you who don’t know, resawing is the ability to cut thin slices or veneers out of a board standing on its edge on the band saw table, while being guided along a high fence. Where this pays off is when you are trying to get maximum mileage out of an especially fine, beautiful, expensive hardwood board.

 

For example, I made a lot of jewelry boxes with 3/8″ thick sides. Considering that I had to sand all of the sides flat and smooth, I found that I could barely get 2 slices out of a 1″ thick board or 3 slices out of a 1 1/2″ board or 4 slices out of a 2″ thick board. You need to allow 1/16″ kerf waste for most band saw blades plus more if your blade wanders, which all blades do to a certain extent. Then all unevenness has to be sanded away in a drum sander or wide belt sander. In the end, you can’t realistically expect to get two finished 3/8″ box sides out of a board that is only 3/8″+3/8″ +1/6″ = 13/16″ thick. You will need not much less than a full 1″ thickness in your original board. Since most hardwood lumber is sold milled down to 7/8″ for a so-called 1″ board, you are faced with only getting one, 3/8″ slice, not two. On the other hand, most 2″ lumber comes milled down to 1 7/8″, which allows you to bet three 3/8″ pieces out, saving you money.

 

The more your band saw blade wanders, the more thickness you will need. The important thing is to minimize this wandering and there are five ways to do this: (1) blade tension (maximum recommended to keep the blade from flexing), (2) blade width (the wider, the better for stiffness), (3) blade type (designed specifically for resawing), (4) motor power (to drive the blade through the wood without bogging down) and (5) blade guides (the more blade control, the better).

 

If you plan on doing a lot of resawing, pay close attention to the specifications of band saws you are considering for purchase, in light of what has been said above. If resawing doesn’t look like it will play a large part in your future, then you are probably more interested in cutting curves in thinner material. In this case, throat depth of your band saw becomes a very important consideration because, on a small band saw, you will be constantly bumping into the back of the throat and you may not be able to complete the curved cuts you have penciled out.

 

Any 14-inch band saw will severely limit the width of cuts you can make to the left of the blade, so consider if this will present a problem for you. If you are planning on just cutting out small parts, fine. On the other hand, if you want to make large parts for furniture, then a small band saw just won’t do. Of course, there is no limitation to the right of the blade, on a 14″ (or any other) band saw, except that you will have to supply auxiliary support for your work piece if it extends very far off the edge of the table. Throat depth is not so much of a problem when you are using the band saw for resawing, although, for resawing, you will need to consider the maximum distance between the table top and the upper blade guide. That measurement determines how wide a board you can resaw on your band saw.

 

When shopping for a band saw, don’t be fooled into thinking that an 18″ band saw will give you a full 18″ between the blade and the back of the throat. Band saws are measured by the outside diameter of their wheels. These wheels are mounted inside the cabinet, one above the table and the other, below. Actually, there is an upper cabinet and a lower cabinet connected by a “column”. The blade travels upwards from the lower (powered) wheel through and inside the column to the upper (idler) wheel before reversing direction and going downwards through the upper blade guide, then the table, then the lower blade guide before returning to the lower wheel.

 

Because the column takes up a certain amount of space, an 18″ band saw will not normally have a full 18″ throat. It will be something less than that, perhaps 17½” (if you are lucky) or even 17″. So, if you need a full 18″ of clearance, you will need a 20″ band saw. Prices climb with throat depth simply because as throat depth increases, the wheels and the cabinets must increase in size accordingly. In short, the whole machine gets bigger.

 

Small band saws with small wheels may not be tall enough to sit on the floor like larger ones. With small band saws, you must either mount them on a bench or purchase or build a stand. Usually the stand is included in the price of the smaller saws. Conversely, when working on a very large, industrial band saw, count on the table top being quite high off the floor to accommodate the lower wheel and its cabinet.

 

When you order blades for your band saw, do so in quantity. There are few sure things in life but blade breakage is guaranteed. Always have replacement band saw blades on hand so you don’t end up breaking your only blade right in the middle of a project. When you do order blades, you can usually find the best prices online but you will need to allow for delivery time and shipping costs. You can buy blades from the saw manufacturer but it is usually cheaper to purchase them from a vendor who specializes in band saw blades. If you can’t find the exact size your band saw uses, you can ordinarily have your blades custom-welded to any length you need.

 

There are times when you want a specialized band saw blade for a specific use like resawing. Here, the challenge is to get a reasonably smooth cut but not to have so many teeth that it causes an undue amount of friction, heat and wandering. In a case like that, it may be best to buy directly from the manufacturer of your band saw. Band saw blades designed to cut tight curves are as narrow as 1/8″. For most curves, I have found 1/4″ blades to be sufficiently narrow. The narrower the blade, the more likely it will be to break quickly but it can track tighter curves than wider blades. For really tight curves, a scroll saw may be a better tool than a band saw. Resaw blades should always be as wide as your band saw can accommodate.

 

There are two basic types of blade guides on band saws: “blocks” and “ball bearing guides”. Blocks can be made out of smooth metal, non-metallic composite or ceramic material. Ball bearing guides are more expensive but are much easier on blades in that there is minimal friction and, therefore, reduced heat. There are side guides in any band saw to restrain the blade from moving left or right and a single block or bearing behind the band saw blade to keep it from moving backward when pressure is applied to the front of the blade by the work piece. After-market ball bearing guides with full installation instructions can be obtained from manufacturers such as Carter. The more expensive band saws come already equipped with ball bearing guides.

 

Like other stationary power tools, very large band saws usually have three phase motors. You should not consider purchasing one of these unless you have three phase power available at the place where you will be using the saw. Three phase power is usually only available from the power company in commercial or industrial areas and cannot be found in residential areas. The only way to have three phase power in a home woodworking shop is to use a phase converter that is large enough for the power requirement of your largest three phase motor. If you plan on running more than one three phase motor at a time, you will need a correspondingly larger phase converter. There are two types of phase converters: rotary (looks like a big electric motor) and electronic. Rotary is better if you can find it. Search for phase converters online.

 

A two speed band saw is useful if you are planning on cutting metal or very dense hardwoods. Running the band saw on the slow setting will mean that while it will take longer to make cuts, it will reduce heat from friction and extend blade life. Metal cutting band saw blades are widely available for cutting mild steel and non-ferrous metals. Never use a metal cutting band saw blade to cut wood. Never use a wood-cutting band saw blade to cut metal.

 

Some band saw wheels are bare metal. If you want to track narrow blades, your band saw wheels should have rubber “tires” that are glued onto or inserted into grooves in the metal band saw wheels. These tires are usually crowned. By adjusting the blade tracking device, you can get the blade to stay in one position on the tires or metal wheels.

 

Another adjustment moves the upper band saw wheel up and down to increase or decrease blade tension. You will need to release this tension to change band saw blades and, on the newer band saws, you can usually find a lever that does this for you. If not, you will have to loosen the tension knob enough to install a new blade on the wheels. Then re-apply the tension, using the blade tension scale, appropriate to the blade width you are using. Wide blades will require more tension than narrow blades. Narrow blades can break if too much tension is applied. Large band saw blades can wander off the band saw wheels if insufficient tension is used. Always refer to the tension scale on your band saw. Don’t guess.

 

After the band saw blade is tensioned properly, disconnect power to the motor and turn the upper wheel by hand to verify that the band saw blade is tracking properly. If not, make appropriate tilt adjustments to the upper wheel until the band saw blade stays in the approximate center of both wheels. A hand wheel or knob is provided on any band saw for this purpose. If the wheels are slightly out of alignment with respect to each other, you can still track a band saw blade. In this case, the band saw blade will be more to the back of one wheel while being more to the front of the other wheel. This discrepancy should eventually be adjusted or “tuned” out of your band saw, but, for now, it’s OK as long as the band saw blade stays on the wheels while cutting. Once you have the band saw blade tracking properly, reconnect the power and start cutting.
