The second step is to use a thin needle mounted in a Pin vice like here in the pic or holding in your hand.With the needle you have to make an initiall point for driling. Do it gently because the join can be broken and the wing can be set apart.To prevent against it you should keep the wing with your second hand quite close to the working area with fingers from top and bottom of the wing.
