I just got a steel city drill press this weekend and the lasor guide. It appears that once you set it up and move the tray up or down or put in a different size piece of wood the X is off. Am I missing something here? If that is true this thing is pretty useless because I can't readjust it for evey piece of wood I drill, kind of defeats the purpose. Besides it is a pin to adjust I already stripped one of the allen heads.
