Make a mark on the blade.
Place a piece of tape on the floor and make a mark to determine your starting point.
Roll the blade in a straight line until the mark you previously made comes back and hits the floor.
Make a second mark on a piece of tape.
Measure the distance between your two marks on the floor. You now know the length of your bandsaw blade!
If you do not have an existing blade, there is a mathematical equation to help determine saw blade length in inches.
- Fix the pulleys or wheels into working position
- In inches, determine the distance from the center hub on the upper and lower band wheels (later referred to as “C”)
- In inches, determine the radius of each wheel. The radius is the measurement from the center hub to the outside of the wheel (later referred to as “R1 and R2”)
- Apply the following formula: (R1 x 3.1416) + (R2 x 3.1416) + (2 x C) = Saw blade length
