I removed that guard quite a few years ago as it's nothing more than a PITA and always gets in your way. Pretty much like I thought, I'm not the only one experiencing this issue of un-square cutting.
As Norm suggested and I've done in the past and that's take a few different bites at it and then use the side of the blade as a disc sander. I've always gotten there in the end I guess but just wondered if there was just something that was uniquely wrong with mine of if it was just me.
Cheers, BB.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
