This might be a stupid question on measuring and cutting but I will ask anyway. Many, many years ago, when I was only elbow height to my own father, he showed me that you measure at least twice and THEN you cut. He also told me that when you draw the 'cut line', that the line 'ends' the piece that you want, so you should always cut just past the line. Made sense so I have always followed that. I recently had a conversation with a neighbor (woodworker) who said he always cuts 'on the line'?? When I asked him why, he answered that with a thin kerf blade it doesn't really matter. He went further to say that he sets his stop blocks up to cut that way as well. Thoughts??
