1 4 x 80 bandsaw blade
The full tooth has three cutting edges. It has the top or leading edge and the two sides. The tooth load is created by all edges that cut wood. The tooth width on these type blades are usually twice the width of the body. For instance if the body is.042 then the tooth is usually created to be at least.084. So each tooth is cutting a kerf (path) through the log at least.084. The sides of the tooth are also cutting and adding tooth load. All of the cutting load is distributed into the gullet and most of the stress is at the narrowest place of the band which is the deepest part of the gullet. The body is pulling the tooth through the cut and the tooth is under load and is pried backward in micro amounts and the steel molecules at the narrowest part of the gullet are being stretched and being put under great stress. The bandsaw steel is for basic understanding a spring or spring steel. I say this because it has the ability to stretch a certain distance and return to its original shape.
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.

The reason there is not a side load is the angle of the side of the tooth. The tooth is bent or set at such a sharp angle on the side that only the top corner of about.010 touches the wood fiber. Of course if you run your band excessively dull it does take on more side load. Now compare the gullet stretch per tooth. Remember both band bodies are .042. The set tooth has the total kerf stress divided between 3 teeth. The swaged full tooth carries the entire kerf stress per tooth plus the side load on 2 sides per tooth. It is easy to understand that the full tooth carries twice the load just because of the top width of .084. Then add the 2 sides of load and we have at least 3 times more tooth load per square inch than the set tooth bands have. What does this mean? From my experience the set tooth pound for pound will perform 2 to 3 times better than a full tooth of the same band width and thickness. This is true even if a special steel is welded to from the full tooth. Let me talk about the body of the band for a bit here. I have spoken of the distortion and how it changes the middle portion of the band to dish on the log side.
With the easy slide system it makes it easier to cut the meat as the smooth moving table reduces the effort and increases productivity. Safety features include a brake motor that ensures the blade stops immediately when the unit is switched off or when the doors are opened. The Butcherquip Table Top Bandsaw also referred to as the Junior Bandsaw is a smaller unit at 92 kilograms that fits onto a table or counter top. It has a power output of 1.1 kilowatts with 230 volts. This catering equipment is ideal for cutting frozen or fresh meat poultry and fish. It is made of cast aluminium it is quite easy to clean and all the work surfaces that touch food are made of stainless steel. For safety purposes it has a safety switch on the access doors and an electronic motor brake which stops the blade instantly when the door is opened or if the unit is switched off.
