For minimum sag and distortion a beam like your surface plate should be supported at its Airy points. These are two points located symmetrically a distance of:

Why would they support a precision plate anywhere other than the Airy/Bessel points while grinding?
Hi Kevin,I know it's expensive...but I use WD 40 also...but then again..I only have a 12 x 18 plate Dave
