When you purchase a band saw blade, it should come with specifications from the manufacturer that tell you exactly how long it needs to be for your saw. If it doesn’t, you can use these steps to determine what length you need.
- First, put the pulleys/wheels in their working position on your saw.
- Determine the distance from the center of the hub on the upper and lower wheels.
- Determine the radius of the upper and lower wheels.
- se the following formula: (R1 x 3.1416) + (R2 x 3.146) + (2 x C) = length.
If you have any questions you should contact the manufacturer of the saw or band saw blades to make sure.
