I learned how to cope a inside corner by a simple hand coping saw on Internet --- have a 45 degree angle cut, then cope. I did some practice yesterday, the result was frustrating. I don't know where I did wrong. Is 45 degree angle cut just for the molding with 45 degree spring angle, or for both 45 and 38 degree spring angles.
My molding is 38 degree spring angle. Should I have 38 degree angle cut then coping?
