Cutting Door Casing 45 degrees
I am replacing original 2-1/4" colonial casing with a larger 3-1/2" x 1-1/16" (Adams Casing) around my doors. I have done this many times with no problems. I have a 12" Hitachi miter saw.
When I am now cutting the 45 degree angles on the casing the saw is not cutting a straight line. It actually has a curve to it with the middlle of the casing the high point (convex shape).
Help! Why is it doing this? The blade isn't that old. Is this a blade issue? It is an 80 tooth carbide tip blade.
Thanks for any guidance.
