A bandsaw is perhaps the first and most important table tool anyone will get for their own personal workshop. Sure bandsaws are used by commercial companies but for now we are concentrating on the residential community and their need for bandsaws. Do you need a bandsaw? Which one is right for you? What will a bandsaw really do for me? These are all the questions pondered by prospective bandsaw owners around the world. Well the truth is that only you can truly answer those questions. You can study you can read and you can take advice but when it comes down to it you are making this decision based on a compilation of all the information you received. What Does A Bandsaw Do? Bandsaws are generally used to saw a material - generally wood - into precise sizes for your project.
On being pushed harder this will bend more but quarter inch is a distinctive point at which it wont deflect easily. In case you are able to deflect it more than a quarter inch add more tension till the deflection equals quarter of an inch. Stock Control: Any superior bandsaw blade is designed to cut across straight lines. Yet each blade does that in its characteristic way. Thats because each blade acquires its exclusive "lead angle". So how can one find out this exclusive lead angle? Many suggest referring to some Resaw Guide. Its like one point that enables you to alter your feed angle your to the blade. One takes time getting used to this method. Additionally it demands steady attention. Having once determined the right direction for feed adjust the fence of bandsaw accordingly and keep cutting straight lines.

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.
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.
