I need help figuring out the correct angle to cut outside corner molding when installing it around a hall entrance. The corner molding is 90 degrees (to cover up where the wall corner meets, looks like this: http://mouldinginstallation.com/how-...molding-0-jpg/), and I'd like to do one side, and the top of the hall entry. Flawed thinking...cutting at a 45 degree angle, like when making window frames, does not work. I do not think this would be a compound cut, but the angle has me perplexed, being two-sided.
Thanks for suggestions.
