Tooth Setting and Sharpening
I have begun playing around with the tooth setter, and have noticed a couple things. When I set my teeth, some of the blades appear to have lost their set only on one side. Is this normal? The blades are still sharp. I set the teeth on one and sawed about 600 bf on 1x material before it began to get wavy, which would tell me it has again lost its set. Do you sometimes just set them without resharpening to prolong the life of the blade?
From contributor A:
If you have a good sharpener, the blade should keep the set evenly, both sides. You should never set without sharpening. You have to understand how blades cut, and understand the engineering of sharpening blades.
How can you tell if the blade is still sharp without a microscope? A bandsaw blade only cuts with .004 of the tip of the tooth. This is one of many reasons you are getting wavy cuts. I could write a book on everything that it takes to sharpen and set blades correctly. Call Cooks Saw and talk to the experts about your blade problems. Talk to Stephen or Tim Cook. They should help you understand more about the problems you are having.
From the original questioner:
The reason I know it's sharp is I set the teeth and put it on the mill and watched it saw like a new blade. I wouldn't know what to look for with a microscope, but I know what a sharp blade saws like.
From contributor T:
Had a bearing replaced on a guide which was about 1/16" too wide. This caused one side to slightly flatten set. Anything that touches the teeth can cause the set to change, including guides. If you have metal wheels, check the band/belt for wear allowing blade to touch the metal part of the wheel. Also, be sure the blade is tracking properly on the wheels.
