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.

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.

Making two interesting toys from wood by using band saw.

Do you think you can create wooden toys to present your children? It is definitely possible by using a best band saw. Actually, the best band saw is such a useful machining tool for woodworkers. However, everyone can use it to create numerous wood toys. Here is an instruction for you to make a wooden car as well as helicopter. Follow it and plan to do now.

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.
