1) for right- handers; hold bow in your right hand at the end with the clove hitch. String should remain loose
2) your pinky finger will be placed directly over or slightly behind the clove hitch
3) the bow will be placed as far up as it can go between the thumb and index finger, the fingers will wrap around the bow string, and...
4) the bow string will be pushed down with the thumb
5) the bowstring is centered across the thunb. This will allow you to control the tightness when you spin the drill.

Using the above technique, you should not experience any difficulty using  nylon cord
