Physical depth check of mesh surface 1. I wanted to see what the mesh surface would look like and how well I could get into the corners. Z axis on the mill was acting up so I set the height optically. It is around one thou and change. Two thou seems to be good for over-all relief. In this test I cut the perimeter first with a four thou D-bit and then plowed the middle by eye with a well used 1/32 endmill. I think better hand feed could help the finish. Doing it the way I did, the bigger EM burred over the corners cut by the D-bit. I dug them out with an exacto ground into a scraper. It was not really keen enough for the task. As far as benching is concerned, I'll need to make some new abrasive pads to clean up the surface.
