I have a long piece of chair rail molding that has already been bevel cut. I assume it's at 45 degrees but it was already in place on an existing wall and I removed it to replace a piece of drywall behind it. Now I want to re-install it
I want to intersect it with a shorter piece (yet to be cut)
How can I cut the shorter piece to intersect snugly with the longer piece. I don't want to cut the longer piece with a coping saw if I can help it. Is there another way.
