I am just a simple man.
Maybe someone could provide a simple test procedure for checking straight edges such as triangles and rulers. Perhaps a trueing procedure also.
I know strings pilled tight are straight. Perhaps that is a good reference.
This would be for non machinists, for non critical use such as checking stone flatness.
