I am making a little cabinet from plans in Woodsmith. It calls for 1" wood & I'm using 3/4" so I have to make some small adjustments. There are three shelves which sit in dadoes cut in each side. The two top shelves have doors between them, so the distance between the dadoes is important to the fit of the door, which I've already made. I measured the doors at least 5 times, left the proper space at the top & bottom & laid them in place to make sure I cut the dadoes in the proper spot. I also measured this at least five times, put my line on the side & cut the dadoes on the wrong side of the line, so I'm off by about an inch! I guess the the solution is to remake the sides of the cabinet or make the doors a little longer, I'm think I'm going to make the doors an inch longer & hope it looks OK.
