I have a PM66 with a Leecraft zero clearance insert and a Forest WW2 blade.
The saw, when lower than the insert is whisper quiet(5HP). But once it is
up in its insert, which has already been plowed out, it makes noise as if it
is still rubbing on the sides slightly? Is this common? I would think once
it has made its cut, it would be quiet?
