The hook tooth blade cuts a 10º rake angle that is highly priced by bandsaw users around the world. (c) Skip Tooth - These are the perfect blades for softer and easier types of materials. This is considered a perfect all-purpose blade. This is also highly prized because it is an excellent blade for resawing. This skip tooth blade cuts a 0º rake angle making it perfect for the average user. These blades are probably the most used by bandsaw users. What It All Means The more teeth your blade has per inch the smoother the cut by the blade you will get. However the smoother the cut the slower the operation actually takes. Most bandsaw users recommend having at least 3 teeth in your material at every turn of the blade. This gives added security to your project keeping you safe from harm.
A bandsaw blade has to be matched to the job in hand and to a lesser extent to the size of the bandsaw. You would not try to rip a 2" board with a tenon saw nor crosscut plywood with a greenwood saw. You would select the right blade for the job and the same is true for a bandsaw. Just because the machine is powered does not mean that one blade will cut everything it wont. So we need a selection of blades dependent on what we are doing. Fortunately despite there being a vast array of blades to choose from we can do 99% of our normal work with just two or three different blades. Blade width Given that the challenge with a bandsaw is to get it to cut straight it is easy to think that the wider the blade the better and to a certain extent this is true. You are likely to get better results with a ½" or ¾" blade than a ¼" one. But the temptation is to go as wide as the wheels will take. Which is an inch or more.

A curved surface allows a roll that can pinch the band and cause a roll that could pull a hand into the blade. Now with the flat center of the log on the bandsaw table it is safe to cut a circle out of the half section of log. One of the easiest ways to do so is to cut out a series of circles from cardboard ranging from the smallest bowl you intend to turn to the largest your lathe will handle. There is no point in trying to turn an eighteen inch bowl on a fifteen inch lathe it will simply not fit. Having tacked the circle to the log section it is simply a matter of cutting out the outline of the bowl by following around the circle. Take your time and allow the sawdust to clear the cut in the green wood. The heat of the cut can cause the dust to expand. However the pitch of the saw will change with a clogged cut and slowing the cut will allow the dust to clear the pitch to drop and the cut to continue. Once there is a flat surface on which the log section can ride the log can be trimmed to widths desired for squares. Each width can then be laid on its side and squared off. It is not necessary most of the time to be fussy about the surfaces as they will be turned away.
This causes a band to start diving into the log in an uncontrolled manner. Remember that distortion is caused when a band is driven with a tooth load greater than the body steel is capable of withstanding and still return back to its original shape. Any bandsaw that is pushed to this point of stretch has become distorted. This will cause the band to not run good and it will dive into the log because of the natural change of curvature called anti-clastic curvature. Myth of restoring bandsaws debunked: When this happens the band cannot be restored to new by the Saw Repairman/Sawfiler. However the sawfiler can distort the middle of the back of the band to equal the front stretch/distortion. Of course for those who know the term this is called benching. This is when a roller or hammer is used to expand/distort the molecules to match the front distortion. The roller stretches the molecules by elongating them as it is pressed between two specially shaped steel rollers. The hammer expands the molecules in a star burst shape to achieve the distortion of making the middle of the band back longer. The hammer needs to be crowned to give a star burst expansion.
