I have bought two 1-1/4" blades for my saw that are 0.042 thick that I wanted to use for planking out some firewood. To tension them being that thick would put my saw frame at the max.
They worked ok but it was "puckering" to tension up. I won't be using them again, too much stress on machine and operator.
Looks like they have some recommended blades higher up on the page for green log cutting
