A Handy Guide on Bandsaws 

by Raymond Archambault

Using a bandsaw, you can create a broad variety of furniture designs. For example, it may be used to cut beautiful moldings and other craft work with ease. 

To make curved cuts in timber lumber, a bandsaw is an ideal tool. 

The following suggestions from our specialists will help you to get the most of this cutting machine in a variety of jobs.  In order to begin, though, let us review the fundamentals.

The Basics of Bandsaws

Bandsaws come in a variety of sizes and pricing points, but their basic function stays the same. Two wheels, a blade with teeth, a motor, and the cutting table are the four main components of a woodworking instrument like this.

The steel blade is passed through a table by both wheels as it rotates. The wood pieces are held in place by components that move with the revolving blade.

These cutting machines are available in tabletop form, which can be secured with a few bolts, as well as large and pricey stand-and-floor-top variants. While bench top band saws are convenient, they lack the cutting capability of their floor-mounted counterparts.

If you don’t have a lot of room in your workshop, these portable versions are ideal. They are best suited for smaller tasks because of their availability in nine- and ten-inch sizes. You could experience some increased vibration as a result of their small weight. Also, there are only a few blades to choose from, limiting your options.

For the most part, floor versions are 14 inches in diameter and are heavy and vibration-free thanks to casting iron components. A wide variety of blades is available, as well as a better cutting performance than tabletop choices.

Because of their versatility and usefulness, they have a high price. So, you might ask yourself, is it really worth it to spend the money on a tabletop band saw? Yes, if you’re an amateur or professional woodworker. It’s especially useful if you’d like to learn how to resaw.

The following instructions will help you use your bandsaw safely and effectively. Let’s have a look.

 

Right Get the Adjustment Right

According to the directions, you should adjust the blades and the guide. When changing the blade or installing a new one, loosen the tension. More tension is required to keep the broad blade in place.

Some blades can shatter if they are under too much strain. Before cutting anything, turn off the band saw, remove the guards, and check to see if the blade is running in the correct direction.

The blade guide is the next step. Keeping the blade’s backside close to the rear guide is critical. Both of the guides should not be touched by the blade. The guides should be in direct contact with the cutting material when pressure is applied to the blade. Before using a band saw, be sure to follow all safety guidelines and use eye protection.

 

Cutting Properly

Slowly and steadily pull your wood stock toward the blade, drawing a pencil line along the way. The blade will curve and the cuts will not be straight if you push out of the line.

Cutting at a lower radius than a blade can tolerate might result in the edge of the wheel slipping off. When making uneven cuts, be sure to keep the waste area outside. Because it will be more difficult to manage the smaller connecting cuts after you have cut a big curve, do them first.

Bandsaw Blades

Choose the Right Blades

The blade that comes with your band saw can be used again. To get the best results, we recommend changing it out according to how often you’re using it. Blades with hardened teeth are always preferable to freshly pressed ones.

Although hardened-teeth blades are more expensive, they are more effective and provide you high with accuracy. When it comes to picking out the right blades, you should keep these two things in mind, in addition to their construction quality.

To cut through solid wood and straight lines, you’ll need a wide blade. To cut curves, though, you’ll need a thin blade. It’s easier for the blade to make tight bends when cutting if it’s narrower. Using a band saw with one of the smallest blades, a 3 1/16-inch radius could well be cut.

The number of teeth per inch (TPI) determines a blade’s speed. If you’re looking for a smooth finish, you’ll want to go with the higher TPI unit. Blades with low TPI, on the other hand, could be used for thick timber.

So that you can choose the right tool for the job, keep both broad and narrow blades on hand.

In contrast, medium-sized blades with a width of 3/8 to 1/4 inches are the most efficient. If you use one of these blades, you won’t have to be buying new modules all the time. Because of its adaptability, such a blade can be used for a broad variety of tasks.

 

Cutting Nonferrous Matter

To cut aluminum, thin brass, or copper, you’ll need a blade with a lot of microscopic teeth. The teeth need to be toughened, otherwise, the blade will wear out too soon.

Nonferrous metals can be cut with a Dakin-Flathers band saw blade.

Bandsaws

Get Zero Clearance ASAP

When an offcut becomes stuck in the throat plate of the saw, just adjacent to the blade, it is inconvenient and slows down the cutting process.

When faced with a dilemma like this, there is a simple solution. Take a thin cardboard cereal box and cut a kerf, and then tape it on to the surface of the table.

 

Making Relief Cuts

Do the workpieces have a contoured profile? Using a jigsaw, cut along the curves and at all transition points to make the process more efficient. When you get to these relief cuts, you’ll see that the waste wood will fall away.

These cuts shorten the length a blade must travel to achieve a contoured cut. As a result, making fine cuts with great precision is a cinch.

 

Begin Cutting from Shallow Angles

Do you need to create a curved cut? Then, begin at the shallowest point possible.

It’s possible that the blade will stray off the path and snap off if you finish the cut at a shallow angle. If the ends are both shallow, then cut them in half from one end to the other, starting at the shallow end.

 

Get Better Performance by Rounding Up Your Blades

After removing the back corners with a saw blade sharpening stone, round the entire back.

The procedure should just take a few minutes, but it will extend the life of the blade and make it easier to cut around tight bends. Since the band saw’s blade will be rounder, it will also lead to a lower vibration level.

 

Frequently Replace Worn Out Blades

It’s imperative that you take action immediately. Replace your blades as soon as you observe a decrease in feed rate, difficulties cutting into a straight line, or burning symptoms. Check for debris and minor obstructions that might increase cutting resistance before changing a blade.

In this case, clean the blade with a brush and soak it in a blade cleaner for a while. Another option is to use a cleaning spray like Trend CLEAN/500.

Your Blades Some Breathing Room

Band saw blade tension should not be held for more than three days at a time when it is not in use. Band saw blade tension can be reduced using either a quick-release mechanism or by rotating the tensioning knob on some versions.

Prematurely breaking blades might result from prolonged exposure to a stretched condition. Tracking difficulties will also arise as a result. On the other hand, reducing the pressure on the blade while not in use can lengthen its lifespan.

 

Expand Your Worktable Space

Using your table saw, cut a hardwood board into a square measuring 24 inches square. Use a cleat to align the new block with your band saw after cutting the blade slot using a table saw.

Installation is as simple as finding and drilling a few screws into the front of your band saw to secure it firmly in place.

 

Deploy Some Cool Blocks

Steel square guide blocks are standard equipment on older band saws. Such blocks may rapidly dull the teeth of a blade if they touch it. Cool blocks, on the other hand, are constructed of a non-metallic composite substance that includes dry lubricants.

Furthermore, these blocks do not harm the teeth of the blades. Unlike steel blocks, they can be installed simply by pressing them on the blade.

 

Coil Your Blades for Safe Storage

Before hanging the blade on the hook, rotate it 360 degrees with your wrists. Protect your hands by wearing gloves and holding the blade away from your body. Place the blade between your foot and a piece of wood to keep it steady.

Press the blade into an oval shape with your hand. Slowly rotate your hand to allow the blade to follow your movements. Keep a firm grip on the blades to ensure that they don’t fall out of your grasp. Continue to turn the blade with your hand until it forms a full coil. To secure the coiled blade, use both hands.

 

Pay Attention to the Manual

If you follow the accompanying rules and read the provided directions, using the band saw will be a breeze for you. You’ll be able to use the information to get accurate results after becoming familiar with the internal workings of the device.

In order to achieve perfection, you must put in the hours of practice. You can never stop learning and growing by taking on new challenges, so don’t be afraid to get your hands dirty!
