I use clear plastic tubing(as long as you want)for large horizontal (fencing,floor leveling with the idiot stick)leveling applications.Just fill it with water and let settle,mark both ends,use one as a control(bench mark)and you can level from here to Worths house.I made a triangle and atttached a plumbbob to it with marks for common angles,triangle at top,bottom rail center would be true plumb,turn 90 degrees and make perfect large timber crosscut marks(after using water level to position level sawhorses).Take a reel snap box(chalk box) attach a plumbbob to it and you have a reel in plumbbob and chalk box combo.A piece of wood and some metal expanding mesh makes the best drywall rasp.
