Take the knob off again.

Then observe the bottom part of the knob. Turn the outer part of the knob, as you would when changing the Weston or DIN values on the knob window, until the outer hole lines up with the threaded hole where the screw goes in.

Insert the screw and turn a few times until it is engaged. Don't turn too far that the tip of screw goes out on the other end.

Put the knob back and turn until its set in place. When turning, make sure that the outer ring of the knob doesn't lift. Otherwise, the outer hole may become misaligned with the set screw inside. Tighten the screw to keep the knob in place.

Thanks for all kind help and suggestions, especially Zorkikat, John Neal and Youxin Ye.

My problem has been solved. I used a strong light source help to look into the outside hole and locate the inside hole for the screw.

The original reason that I try to remove the wind knob is to get the winding aligned with a leicavit. Now it's perfect.
