If you cannot find it from the previous post try the following.
1) Adjust your blade tension to a central location - away from the stops
2) Carefully measure the diameter of each wheel - at the edge of the tire.
If they are exactly the same diameter, calculate the circumference of ONE
and write it down,
3) Measure between the center of both hubs. This can be difficult depending
on the saw. Just try to get as close as possible. You might need a helper
to hold a level or square at the center point of one while you do the same
at the other. If easy, just remove the table and measure.
Measurement 2) gives you the 1/2 circumference of each wheel. Measurement
3) should be doubled to give you the measurement between each blade tangent
Check your number with a piece of sturdy string and if you are within 1/4"
or so, get a blade. By the way, if you cannot find one hanging on a card
display don't dispair. Most full service tool stores make custom lengths
from blade stock. In some cases they are even cheaper.
Adjust the tension knob to somewhere near the middle of the range of
Measure the diameter of one wheel and multiply by 3.14 .
Measure the distance between the centers of the wheels and multiply by 2.
Add these numbers together.
That's the length of your blade.
