How did you do the diagonal grooves ? I could not use the saw, as i would have damaged the upper part. I could not use a file for the same reason. I somehow managed it, but im curious if there would have been an easier way.
I used a razor saw. I had previously scored a line using a knife to give the razor saw a guide. Rather than using it in the normal way, I drew the blade back/down away from the circular hole, lifted it and repositioned so that I didn't damage the rest of the surface.
