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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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!
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.
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.
- 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.
- 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.
