4/16: I was sanding a practice fiber this morning and with the microscope I noticed sanding marks extending beyond the wings on the "sci-fi" end as well as on the light guide end. Either my sanding this morning was going too far or I had made the marks on a previous occasion of sanding. I think it is this morning's sanding that is responsible for the marks. | 4/16: I was sanding a practice fiber this morning and with the microscope I noticed sanding marks extending beyond the wings on the "sci-fi" end as well as on the light guide end.
