Olympic recurve sight alignment

I should have added, the white tape on the side for custom sight marks is car pin striping tape. I buy it by the roll so i replace it when needed or when i have new marks. Also when attaching the sight bar to the extension, it should be attached so that when the sight aperture is at its lowest, it is still not touching the arrow. Mine is a good example of the aperture at the lowest setting and a finger width above the arrow.
