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?


Mine did the same thing. While the saw is running and with the fence
covering the insert BUT NOT THE BLADE SLOT, raise the blade to further cut
out the slot. Then after a few weeks the noise should diminish with use.
