[Improvised DIY]

My primary reason was visibility for me as the cutting tool and boring head makes it difficult to see the cut (I am a bit short). The second reason was the chips flying in my face when I was cutting over the top and I had my face close to the action to see the chip formation, tool deflection and surface finish. It also eliminated double cutting when the chips becomes stringy. The chatter did reduce as Frank said. The weight of the head hanging while the stock is trying to lift it as opposed to the head hanging and the stock pulling it down also plays a role in the rigidity. Small machines are finicky, and you need to manage your forces.
