Not to forget the little bubble level at the datum or level spot. I bought a set of levels at the 99 cent store and removed all the little bubble levels then sanded a flat spot on them so they don't roll. I also mark the CG area shown on the plans with a 1/8 strip of covering so I always know where the starting point is.
