The GRS Design and Layout Surface is a convenient multi-purpose work surface that mounts into a GRS vise. The 6-inch diameter provides a large work surface. Covered with quality genuine leather for a soft surface that will not damage fine workpieces. Using the Design and Layout Surface provides a flat, stable area for layout under the microscope. Other uses include inspection, assembly, working surface for odd shaped items, drawing table, and more. Fits in all GRS vises. Concept inspired by GRS Training Center instructor Sam Alfano.
