Ok,....I'm missing something. I'm sure I will be criticized for such a dumb question. How are you making the pencil line at the beginning stage? If both long edges of a 5 ft. board are crooked already,..what am I using to make sure my measurement line is straight? In other words,....I need to cut 4 " off the long end of one side of the board. If I measure up 4" from along the edge of the board to make my pencil marks and subsequent line (connecting the dots) it will end up being as crooked as the edge that I'm using as my guide. That's what is throwing me.
