Step 1
Make a mark on the blade.
-
Step 2
Place a piece of tape on the floor and make a mark to determine your starting point.
-
Step 3
Roll the blade in a straight line until the mark you previously made comes back and hits the floor.
-
Step 4
Make a second mark on a piece of tape.
-
Step 5
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
