Stitch welding and lapping the steel baseplate for mounting the HGR25 rails, ballscrew and motor. Base is 8"x1/2" steel plate with stitch welded 1-1/2" x 1" cold rolled flat bar. The rail mounting face was then progressively lapped with abrasive and a granite surface plate. A reference edge for 1 one the linear guideways was added, also lapped and shimmed to be straight using a Starrett straight edge. This weldment is the foundation of the machine, it will be cast into an epoxy-granite mix or a non-shrink precision grout with aggregate, with some other steel components that will become mounting points for the upper axes.
