Any fixed delay would only work over a small range of spindle speeds. If you can afford a couple extra sensors, then you can set them up in quadrature alignment to count gear teeth, and rig some special indicator to make the index pulse. Hall sensors can detect sheet steel "flags", or an aluminum strip can break the beam of an optical sensor. This will work over a very wide range of speeds.
