With the hard-buff you need to press hard enough on the piece to prevent chopping and an uneven finish but if you press too hard you will get rounding of any corners you wish to maintain. With the cloth wheel I have found it is best to clean the wheel with the rake quite often (especially on a fresh wheel) and load the polish on only one half. Moving between the polish-loaded part of the wheel to the other half has given me good results.
I have learned a tremendous amount about the practical process of polishing in the last couple days. We have been working on slugs of metal (pictured below) but are going to start working on practice watch cases tomorrow. I will post some pictures of that later on.
