Here are some pictures of elky mesh on the oval ring.
At this point I used the shortest screws to secure the mesh to the oval in 4 locations. I used the midlength screw to hold the black part to the oval on the top center. The largest size silver screws I used in three locations on the bottom of the black part to attach it to the oval.
Here are the three sizes of trim screws that I used.
I do have more pic if needed, send PM
