"A draw is simple enough if the clubface is closed in the grip, and the machine is adjusted to the right."

You can't draw the ball with a closed clubface, which can only contact the outside of the ball. You are describing a pull hook with respect to the adjusted machine. The "prior" aspect of this procedure does not insure it's "precision". I can Horizontally Hinge more precisely than "guesstimate" how much to close both the clubface and stance.

Sure you can...(infinite doubt inserted here)

If you had read the previous post, you would have seen that the clubface was square to the target, not closed to it. The clubface is closed to the grip but not to the target. Additionally, the club would have to be swung off plane to hit the outside quadrant of the ball with the machine aligned to the right. With this body line, the inside quadrant is the only part of the ball that could possibly be struck, for those of us that don't like plane shifts.
