The purpose of the 29 deg. for the compound is to allow for the heavy cut to
be on one side of the threads while just dusting the other side. In truth,
you can set the compound at any angle you desire and do the cutting as you
deisre. Some ways are just easier to do than others.
Personally, I set the compound whereever it is and work from there.
