X-rated photo - Sharpening a bandsaw blade *PIC*

Russ Fairfield
>There are a couple references to grinding bandsaw blades with a Dremel tool.

The photo shows how to do it. Use the Dremel "Heavy Duty" cut-off wheel and mandrel. Lightly, LIGHTLY, touch the back of each tooth.

Some folks claim that I should be swinging the wheel from side to side to follow the set in the teeth. I have never found that it mattered.

There are some who claim that they can get 6 to 8 sharpenings on a blade. My best is 2 or 3. Grinding the teeth reduces the kerf, and therefore the clearance of the blade in the cut; and that can be a problem in sawing deep cuts in green wood. You might get more mileage with thinner cuts and dry wood.

As for the blade being sharper than new, that depends on the blade. With a cheap blade that isn't very sharp to start with, it will be better than new. With a Timberwolf or other quality blade that is sharp when it is new, this will leave a blade that may be as good as new, but not better than new.

Wear goggles while grinding.
