I tram an 84” Blanchard. What is this? A 42”?

What’s crosshatch?

[@clarkfarrar6683]

It's the pattern of swirl marks in the finish produced on the part. The leading side of the grinding head makes a curve going in one direction and the trailing side of the head makes a mirror image of those curves, so it's a cross-hatch pattern when the geometry between head and chuck is correct.
