I'm mounting a Cummings Spinner on an IO-390 w/Hartzell CS prop. Easy going, but I'm at the point to where I need to align and final drill the spinner.
I'm unsure of the clearance I should give the blade holes for the prop at rest.
I'm also not sure if there is a way to rotate the blades to check clearance, didn't want to damage anything.
Only get one shot at alignment so seeking advice or experience!
Edit: Prop is mounted on the airplane, not torqued or safe-tied.
