Owch, your killing me my friend. Ok, let me explain a bit more. This room currently has no baseboards at all, they were all pulled and stupid me tossed them out or I could have used them as a template. So, what I'm doing is measuring with a ruler on the length of this piece of wall. This wall is basically what separates two stairwells. So, the length from corner to corner is 6 and 3/4 inches. In this case, these are two outside corners. So, if this were a simple straight cut, I'd measure on the saw the length and just cut. However, because I want a 45-degree angle, it would seem that you'd nearly have to include some length for that angle so it juts out far enough to mate up with the other pieces at either end that are also cut at a 45-degree angle. I agree you have to take into consideration the width of the blade etc. I imagine and not being a math wiz at all, the simple tilting of the blade from a 0 position to a 45-degree position would mean you'd have to add on some extra in order to compensate for the angled cut or am I just full of crap and have no clue what I'm talking about. I'm not using my table saw, I don't see this as a job for that, I instead am using my miter saw. Additionally, are you saying a coping saw might help with the inside corners? Can a blind person effectively use a coping saw? I thought I had seen a post that said it would be very difficult for a blind person to use a coping saw. Being as I'm not an expert on anything woodworking related, but trying to learn, I'm in no position to say one way or the other on coping saws and their use. So, I'm open to any ideas, but would of course like to make as few trips from the basement to the saw work location.
