I’ve been noticing that when I’m cutting 45 degree beveled cuts on my table saw for glued miter joints that in the last few inches of the cut my table saw blade seems to be flexing a bit creating a concave surface on the beveled face of the work piece. This usually only happens on a tough hardwood like cherry or hickory. It adds extra sanding time to smooth out so the mitered corners meet properly. Any suggestions on how to reduce this?
I have noticed that a thicker blade, pushing the board threw slowly and keeping the board tight against the fence through out the entire rip will help. Or make your board extra long, make the rip and then chop saw off the bad part.
