Has anyone thought of looking at ACCU Score out of Pennsylvania. They have a gage that is similar to a mic. Any how we use one and it seems to work well with V grooves. I did a study utilizing the V-Gage and a microscope. Results were within .005". Utilizing a Eye loupe Comparator...the results were that the comparator was .008 - .010" on the high side....any comments...
