I have some door trims that need replacing and I want to match them with the rest of the house. I tried doing a straight mitre but they don't look as good and because it's an old house the door isn't perfectly square anymore.
With these which I tried to cut unsuccessfully, a bit of movement out of square doesn't matter because the profile fits into it. But as I say, I've not managed to cut them. I'm sure there is an easy technique. How do you do it?
